Amnesia: Pathologic partial or complete loss of the ability to recall past experiences (AMNESIA, RETROGRADE) or to form new memories (AMNESIA, ANTEROGRADE). This condition may be of organic or psychologic origin. Organic forms of amnesia are usually associated with dysfunction of the DIENCEPHALON or HIPPOCAMPUS. (From Adams et al., Principles of Neurology, 6th ed, pp426-7)Amnesia, Retrograde: Loss of the ability to recall information that had been previously encoded in memory prior to a specified or approximate point in time. This process may be organic or psychogenic in origin. Organic forms may be associated with CRANIOCEREBRAL TRAUMA; CEREBROVASCULAR ACCIDENTS; SEIZURES; DEMENTIA; and a wide variety of other conditions that impair cerebral function. (From Adams et al., Principles of Neurology, 6th ed, pp426-9)Amnesia, Anterograde: Loss of the ability to form new memories beyond a certain point in time. This condition may be organic or psychogenic in origin. Organically induced anterograde amnesia may follow CRANIOCEREBRAL TRAUMA; SEIZURES; ANOXIA; and other conditions which adversely affect neural structures associated with memory formation (e.g., the HIPPOCAMPUS; FORNIX (BRAIN); MAMMILLARY BODIES; and ANTERIOR THALAMIC NUCLEI). (From Memory 1997 Jan-Mar;5(1-2):49-71)Amnesia, Transient Global: A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours. During the period of amnesia, immediate and recent memory abilities are impaired, but the level of consciousness and ability to perform other intellectual tasks are preserved. The condition is related to bilateral dysfunction of the medial portions of each TEMPORAL LOBE. Complete recovery normally occurs, and recurrences are unusual.

In these pre-excitation syndromes, atrial impulses often bypass the ATRIOVENTRICULAR NODE delay and travel via ACCESSORY CONDUCTING PATHWAYS connecting the atrium directly to the BUNDLE OF HIS.Neurons: The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.Tachycardia, Atrioventricular Nodal Reentry: Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.Coatomer Protein: A 700-kDa cytosolic protein complex consisting of seven equimolar subunits (alpha, beta, beta', gamma, delta, epsilon and zeta).

It causes motor depression, ataxia, and changes in mood, perceptions and feelings, and is a potent excitatory amino acid agonist.Thiamine Deficiency: A nutritional condition produced by a deficiency of THIAMINE in the diet, characterized by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the United States most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption. In countries relying on polished rice as a dietary staple, BERIBERI prevalence is very high.

Anterograde and retrograde amnesia after lesions to frontal cortex in rats. (1/47)

A socially acquired food-preference test was used to assess effects of lesions to the frontal cortex on anterograde and retrograde memory in rats. In Experiment 1, there was no effect of lesion when rats were administered a two-choice test in which the target food was to be selected in the presence of a single distractor. In Experiment 2, a three-choice memory test was administered in which the target food was presented along with two equally palatable alternatives. In the latter test, lesioned groups displayed anterograde amnesia that increased with the length of the interval between postoperative acquisition and test, and a severe retrograde amnesia that extended equally over the entire range of intervals between preoperative acquisition and test. This outcome, which contrasted with the pattern of memory loss previously observed in rats with hippocampal lesions on this test, was interpreted as evidence for the strategic role of the frontal lobes in directing response selection and retrieval processes in memory.  (+info)

Brain correlates of memory dysfunction in alcoholic Korsakoff's syndrome. (2/47)

OBJECTIVES: To investigate the relation between anterograde amnesia and atrophy of brain structures involved in memory processing in alcoholic Korsakoff's syndrome. METHODS: The volume of brain structures involved in memory processing was measured with MRI from 13 subjects with Korsakoff's syndrome, 13 subjects with chronic alcoholism without Korsakoff's syndrome, and 13 control subjects. The brain structures analysed were the hippocampus, the parahippocampal gyrus, the mamillary bodies, the third ventricle, and the thalamus. Brain volumes were correlated with the delayed recall of a verbal learning test. RESULTS: Compared with subjects with chronic alcoholism and control subjects, subjects with Korsakoff's syndrome had a reduced volume of the hippocampus, the mamillary bodies, and the thalamus, and enlargement of the third ventricle. The impairment of delayed recall correlated with the volume of the third ventricle (r=-0.55, p=0.05) in the Korsakoff group. CONCLUSIONS: Anterograde amnesia in alcoholic Korsakoff's syndrome is associated with atrophy of the nuclei in the midline of the thalamus, but not with atrophy of the mamillary bodies, the hippocampus, or the parahippocampal gyrus.  (+info)

Pharmacokinetic-pharmacodynamic analysis of mnesic effects of lorazepam in healthy volunteers. (3/47)

AIMS: To describe the pharmacokinetic-pharmacodynamic modelling of the psychomotor and mnesic effects of a single 2 mg oral dose of lorazepam in healthy volunteers. METHODS: This was a randomized double-blind, placebo-controlled two-way cross-over study. The effect of lorazepam was examined with the following tasks: choice reaction time, immediate and delayed cued recall of paired words and immediate and delayed free recall and recognition of pictures. RESULTS: The mean calculated EC50 values derived from the PK/PD modelling of the different tests ranged from 12.2 to 15.3 ng ml-1. On the basis of the statistical comparison of the EC50 values, the delayed recall trials seemed to be more impaired than the immediate recall trials; similar observations were made concerning the recognition vs recall tasks. CONCLUSIONS: The parameter values derived from PK/PD modelling, and especially the EC50 values, may provide sensitive indices that can be used, rather than the raw data derived from pharmacodynamic measurements, to compare CNS effects of benzodiazepines.  (+info)

Amnesia due to fornix infarction. (4/47)

Background and Purpose-The fornix connects various structures involved in memory. We report a patient with anterograde amnesia after an acute ischemic infarct in the anterior fornix. Case Description-A 71-year-old female with acute-onset amnesia had neuroimaging studies showing ischemic infarction of both columns and the body of the fornix and the genu of the corpus callosum. Neuropsychological evaluation revealed anterograde amnesia without evidence of callosal disconnection. The patient showed marked improvement in her memory function on the follow-up visit. Conclusions-Amnesia in this case is likely due to infarction of the anterior fornix structures.  (+info)

Bilateral astrocytoma involving the limbic system precipitating disabling amnesia and seizures. (5/47)

Astrocytomas involving the limbic system are usually unilateral in nature. We report a very unusual case where a low-grade astrocytoma originating in the left temporal lobe spread to the right hippocampus through the hippocampal commissure to cause disabling amnesia and seizures. Some improvement in the memory deficit was facilitated by identification of complex partial status epilepticus. EEG should be performed in all patients with lesions of the limbic system and neuropsychological problems if ongoing seizure activity is not to be missed.  (+info)

Focal autobiographical amnesia in association with transient epileptic amnesia. (6/47)

Although problems with remembering significant events from the past (e.g. holidays, weddings, etc.) have been reported previously in patients with transient epileptic amnesia (TEA), to date there have been no detailed studies of autobiographical memory in patients with this disorder. To investigate this issue, a 68-year-old right-handed man (R.G.) who suffered from TEA and reported significant autobiographical memory problems was tested on a battery of neuropsychological tests of anterograde and remote memory. Tests of autobiographical memory revealed that R.G. was unable to evoke detailed autobiographical recollections from a substantial part of his life. By contrast, he performed well on tests of new learning and general knowledge and possessed good personal semantic information about his past. In summary, a distinct form of autobiographical amnesia, which is characterized by loss of experiential remembering of significant events, may be associated with TEA. It is proposed that the autobiographical memory deficit seen in the disorder may result from the progressive erasure of cortically based memory representations. This case adds to growing evidence for a dissociation between mechanisms subserving anterograde memory and those required to evoke remote episodic memories.  (+info)

Cognitive impairment after small-dose ketamine isomers in comparison to equianalgesic racemic ketamine in human volunteers. (7/47)

BACKGROUND: Ketamine is increasingly used in pain therapy but may impair brain functions. Mood and cognitive capacities were compared after equianalgesic small-dose S(+)-, R(-)-, and racemic ketamine in healthy volunteers. METHODS: Twenty-four subjects received intravenous 0.5 mg/kg racemic, 0.25 mg/kg S(+)-, and 1.0 mg/kg R(-)-ketamine in a prospective, randomized, double-blind, crossover study. Hemodynamic variables, mood, and cognitive capacities were assessed for 60 min. RESULTS: Transient increases in blood pressure, heart rate, and catecholamines were similar after administration of all drugs. At 20 min after injection, subjects felt less decline in concentration and were more brave after S(+)- than racemic ketamine. They reported being less lethargic but more out-of-control after R(-)- than racemic ketamine. Ketamine isomers induced less drowsiness, less lethargy, and less impairment in clustered subjective cognitive capacity than racemic ketamine for the 60-min study. Objective concentration capacity [test time, S(+): 25.4 +/- 15.2 s, R(-): 34.8 +/- 18.4 s, racemic ketamine: 40.8 +/- 20.8 s, mean +/- SD] and retention in primary memory [test time, S(+): 4.6 +/- 1.2 s, R(-): 4.2 +/- 1.4 s, racemic ketamine: 4.0 +/- 1.4 s, mean +/- SD] declined less after S(+)- than either R(-)- or racemic ketamine at 1 min. At 5 min, immediate recall, anterograde amnesia, retention in primary memory, short-term storage capacity, and intelligence quotient were less reduced after the isomers than racemic ketamine. Speed reading and central information flow decreased less after S(+)- than racemic ketamine. CONCLUSIONS: Early after injection, ketamine isomers induce less tiredness and cognitive impairment than equianalgesic small-dose racemic ketamine. In addition, S(+)-ketamine causes less decline in concentration capacity and primary memory. The differences in drug effects cannot be explained by stereoselective action on one given receptor.  (+info)

Isoflurane causes anterograde but not retrograde amnesia for pavlovian fear conditioning. (8/47)

BACKGROUND: Production of retrograde amnesia by anesthetics would indicate that these drugs can disrupt mechanisms that stabilize memory. Such disruption would allow suppression of memory of previous untoward events. The authors examined whether isoflurane provides retrograde amnesia for classic (Pavlovian) fear conditioning. METHODS: Rats were trained to fear tone by applying three (three-trial) or one (one-trial) tone-shock pairs while breathing various constant concentrations of isoflurane. Immediately after training, isoflurane administration was either discontinued, maintained unchanged, or rapidly increased to 1.0 minimum alveolar concentration for 1 h longer. Groups of rats were similarly trained to fear context while breathing isoflurane by applying shocks (without tones) in a distinctive environment. The next day, memory for the conditioned stimuli was determined by presenting the tone or context (without shock) and measuring the proportion of time each rat froze (appeared immobile). For each conditioning procedure, the effects of the three posttraining isoflurane treatments were compared. RESULTS: Rapid increases in posttraining isoflurane administration did not suppress conditioned fear for any of the training procedures. In contrast, isoflurane administration during conditioning dose-dependently suppressed conditioning (P < 0.05). Training to tone was more resistant to the effects of isoflurane than training to context (P < 0.05), and the three-trial learning procedure was more was more resistant than the one-trial procedure (P < 0.05). CONCLUSIONS: Isoflurane provided intense dose-dependent anterograde but not retrograde amnesia for classic fear conditioning. Isoflurane appears to disrupt memory processes that occur at or within a few minutes of the conditioning procedure.  (+info)

Begin taking Ambien zolpidem with minimal therapeutic dose, which is associated with dose-dependent expression of the side effects of Ambien. For the prevention of anterograde amnesia, sleep after taking Ambien should be at least 8 hours. If for any reason the patient can not afford to sleep as much time he should stop using Ambien zolpidem.. It is necessary in the near future to go to sleep, as the effect comes quickly. Otherwise, development of anterograde amnesia is possible.. Stop taking the drug should be gradual, in order to avoid the development of ...
Henry Molaison, formerly known as H.M., changed the way people thought of memory. The case was first reported in a paper by William Beecher Scoville and Brenda Milner in 1957.[30] He was a patient who suffered from severe epilepsy attributed to a bicycle accident at the age of nine. Physicians were unable to control his seizures with drugs, so the neurosurgeon Scoville tried a new approach involving brain surgery. He removed his medial temporal lobe bilaterally by doing a temporal lobectomy. His epilepsy did improve, but Molaison lost the ability to form new long-term memories (anterograde amnesia). He exhibited normal short-term memory ability. If he was given a list of words, he would forget them in about a minutes time. In fact, he would forget that he was even given a list in the first place.[31] Once Molaison stopped thinking about the lists he was unable to recall them again from long term memory. This gave researchers evidence that short-term and long-term memory are in fact two ...
A classical model of memory developed in the 1960s assumed that all memories pass from a short-term to a long-term store after a small period of time. This model is referred to as the "modal model" and has been most famously detailed by Atkinson and Shiffrin (1968). The exact mechanisms by which this transfer takes place, whether all or only some memories are retained permanently, and indeed the existence of a genuine distinction between the two stores, remain controversial topics among experts. One form of evidence, cited in favor of the separate existence of a short-term store comes from anterograde amnesia, the inability to learn new facts and episodes. Patients with this form of amnesia, typically caused by damage to the hippocampus, have intact ability to retain small amounts of information over short time scales (up to 30 seconds) but are dramatically impaired in their ability to form longer-term memories (a famous example is patient HM). This is interpreted as showing that the short-term ...
Focal damage to the fornices is uncommon and may be due to surgical removal of ventricular cysts and tumours.1 We report a case of bilateral fornix infarction with reduced fractional anisotropy values at 3 T after anterior communicating artery aneurysm clipping.. A healthy 33-year-old woman was admitted to our hospital with the incidental finding of an anterior communicating artery (ACoA) aneurysm on magnetic resonance angiography. Neurological examination was normal. Digital subtraction angiography visualised a broad based, tapered and 4 mm sized aneurysm of the ACoA and a median callosal artery (fig 1C). The ACoA aneurysm was treated with surgical clipping because of its irregular configuration. After surgery, the patient was drowsy with fluctuating impaired vigilance. She was disoriented in time, space and person, and revealed anterograde amnesia and amnesic aphasia. Her relatives noticed personality changes, psychomotor slowing and decreased spontaneity of speech and behaviour. Apart from ...
This fact was made most famously clear in the case of patient Henry Molaison (H.M.) who post-operatively was unable to form new episodic memories (anterograde amnesia). He was henceforth only living in the present moment, unable to recall past or recent episodes in his life, though he maintained his pre-operative semantic knowledge of himself and the world. Another patient, Clive Wearing, was afflicted with encephalitis that destroyed most of his hippocampus and fornix fibers connecting the hippocampus to the neocortex. Consequently, he is unable to remember anything as recent as 30 seconds ago, though he still manages to play the piano beautifully (see also the article by Oliver Sacks, and the excellent film, Memento, by Christopher Nolan).. While there is still debate regarding the extent to which the hippocampus is necessary for the maintenance of stored information, the general view of hippocampal function resulting from these and a number of animal studies, is that the hippocampus is ...
After hypoxia, a critical adverse outcome is the inability to create new memories. How anterograde amnesia develops or resolves remains elusive, but a link to brain-based IL-1 is suggested due to the vital role of IL-1 in both learning and brain inju
Everyone forgets things a number of the time. You forget why you chose to enter and completely walk right into an area. Youre mid- space and unexpectedly dialog -out what was only said.. Although odd and sometimes embarassing, short-term memory loss below a specific threshold does not mean anything. But if youre experiencing unexplained, sudden and major trouble remembering things that only occurred, maybe its a symptom of a larger issue.. The mind is the seat of recollection. Short-term memory losses typically happen when the brain or nervous system changes for some reason. Here will be the most typical and significant reasons for short-term memory loss, a.k.a "anterograde amnesia," in no specific sequence. ...

Drinking enough alcohol to cause a blood alcohol concentration (BAC) of 0.03-0.12% typically causes a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC from 0.18% to 0.30% causes profound confusion, impaired speech (e.g., slurred speech), staggering, dizziness and vomiting. A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting and respiratory depression (potentially life-threatening). A BAC from 0.35% to 0.80% causes a coma (unconsciousness), life-threatening respiratory depression and possibly fatal alcohol poisoning.. A breathalyzer is a device for estimating BAC from a breath sample. It was developed by inventor Robert Frank Borkenstein[15] and registered as a trademark in 1954, but many people use the term to refer to any generic device for estimating blood alcohol content .[16] With the advent of a scientific test for BAC, law ...

The central nervous system is involved is less than 2% of cases, the meningoencephalitic form being distinctly rare. This 67-year-old man presented with a 4-month history of cognitive decline (anterograde amnesia for recent facts and apathy). On the day before, he complained of headache, vomit, fever and confusion. On admission there was right hemiparesis (attributed to a cerebrovascular accident in 1994), lack of external ocular movements, uneven but light reacting pupils and meningoradicular signs. No papilledema was found. In 1997 he presented a left ventricle myocardial lesion which on biopsy proved to be an echinococcus cyst. Routine laboratory tests were normal. A suboccipital cerebrospinal fluid sample disclosed 95 cells/mm3 (60% neutrophils, 39% lymphocytes and 1% eosinophils); 61,800 red blood cells/mm3, protein levels of 268 mg/dl and low ...
When you doctor has determined that you should stop taking Ambien CR, they will help one to stop taking it gradually. For the prevention of unintentional overdose, it really is important that patients should monitor the dose taken each and every time. This could also be dangerous for your patients, as well as the people surrounding them. Edluar is exclusive because of their sublingual (within the tongue) administration. Until my husband ripped rid of it my head and started yelling at me.

By the time the third quadrennial consensus statement on concussion statement was issued in May 2008 (2), however, there was renewed interest in the role of anterograde amnesia as a surrogate measure of injury severity. The Zurich statement therefore included anterograde amnesia as a modifying factor [7] that might predict the potential for prolonged or persistent concussion symptoms and influence concussion investigation and management. Noting that retrograde amnesia varies with the time of measurement post-injury, the statement continued the expert trend in the 2000s viewing it as poorly reflective of concussion severity. The American Academy of Pediatrics 2010 clinical report on concussions (5), concurred, stating that, [a]long with LOC, [anterograde] amnesia may be an important indicator of more serious injury. A 2011 study (3) by researchers at the University of Pittsburgh, however, found that neither anterograde nor retrograde amnesia were predictive of protracted recovery (21 ...

NMDA-receptor antagonist, is a relatively new drug specially developed for use in moderate-to-severe dementia. This drug may also be effective in the treatment of Korsakoffs amnestic syndrome. We report a case of a 45-year-old woman with WKS, who was treated with 20 mg memantine (Axura) daily for the period of 28 weeks. The patients cognitive status was evaluated using the following tests: mini-mental state examination (MMSE), Buschke selective reminding test, trail making test and Rey-Osterrieth complex figure test. No significant improvement was observed in the patients anterograde amnesia. Larger trials are needed to substantiate the efficacy of memantine for treatment of memory impairment in Korsakoffs syndrome.. ...
The hippocampus is critical to the formation of memories and the retention of them. Damage to the hippocampus can cause both retrograde amnesia (loss of previous memories) and anterograde amnesia (ability to form new memories).. Memory loss is one of the earliest symptoms of Alzheimers disease, and the hippocampus is one of the first areas of the brain to deteriorate.. ...
Injury or trauma to head is the most leading cause of memory disorders. Injury to brain leads to tissue displacement, disruption of vascular channels, subsequent hemorrhage and edema. This damage impairs memory functions and causes a person to loss memory either transient or permanent. Person is unable to recall about what happened with him. If lesion is in hippocampus, some degree of retrograde amnesia occurs in which person fails to recall memories from the past and its lesion can also lead to anterograde amnesia in which people unable to establish new long term memories of those types of information that are the basis of intelligence.. Diseases like Alzheimer leads to memory loss and mostly this disease occur in late age. This is the degenerative disease results in formation of plaques in brain areas and the cortex becomes atrophic. This disease is characterized by dementia in which intellectual functions of brain are disturbed. It widely effects to thinking, talking, judgment and memory. ...

A form of transfer of training in which learning or performance of a task is impaired by training on a different but related task, as when a spell of driving on the right-hand side of the road temporarily impairs ones ability to drive on the left, or vice versa.

Post-traumatic amnesia (PTA) is a state of confusion that occurs immediately following a traumatic brain injury in which the injured person is disoriented and unable to remember events that occur after the injury. The person may be unable to state his or her name, where he or she is, and what time it is. When continuous memory returns, PTA is considered to have resolved. While PTA lasts, new events cannot be stored in the memory. About a third of patients with mild head injury are reported to have "islands of memory", in which the patient can recall only some events. During PTA, the patients consciousness is "clouded". Because PTA involves confusion in addition to the memory loss typical of amnesia, the term "post-traumatic confusional state" has been proposed as an alternative. There are two types of amnesia: retrograde amnesia (loss of memories that were formed shortly before the injury) and anterograde amnesia (problems with creating new memories after the injury has taken place). Both ...
Causes for amnesia can be either neurological or psychogenic. The first implies some physiological damage to one or more of the specific areas of the brain associated with memory, most often around the hippocampus. This can be from a virus like the herpes that left Clive Wearing with no short-term memory capabilities, blunt force trauma, burst arteries or tumours in the brain or the outright removal of certain sections of the brain as in the famous case of H.M. The effects are highly varied; retrograde amnesia (the more well-known type of amnesia - loss of all memory before the inciting incident) as well as anterograde amnesia (loss of ability to form new memories after the incident) have both been reported in different degrees or even in some mixture. Muscle memory and semantic memory often remain, so the patient can still ride a bike and use language, but their ability to learn new skills is more hit and miss. H.M. retained some implicit memory so tasks he repeated often got easier despite it ...

The functional contribution of medial temporal lobe has been studied in the human brain for over half a century. Insight into the nature of this extraordinary structure was discovered when epileptic patient H.M. had an experimental operation to surgically resect his bilateral medial temporal lobes. The procedure resulted in profound anterograde amnesia, demonstrating the critical role of medial temporal lobe in forming new long-term memories; yet a variety of other capacities remained intact (e.g., intelligence, personality, and skills). The notion that medial temporal lobe function was isolated to the formation of new long-term memories persisted for several decades until the development of new methodologies. It has been the endeavor of cognitive neuroscience to further our understanding of the structural organization of complex cognition and behavior. The focus of this dissertation is to provide evidence supporting the functional contribution of medial temporal lobe sub-regions, namely ...
In laboratory studies with nonanxious participants, benzodiazepines (BZ) reliably induce anterograde amnesia. It remains unclear whether memory impairments exist for information presented in therapy among anxiety patients who are concomitantly taking BZs. This naturalistic study compared 16 panic disorder patients who were daily BZ users with 16 age- and education-matched, nonmedicated panic disorder patients. An incidental memory task assessed memory for psychoeducation material on the origins and management of somatic anxiety symptoms presented during group cognitive behavioral therapy (CBT). BZ users showed significantly poorer memory performance than controls although there were no group differences in anxiety symptoms, rates of psychiatric comorbidity, or sedation. Among BZ users, a higher number of minutes away from post peak drug-blood concentration when encoding began, was also associated with better incidental memory performance. Although causation cannot be inferred from this ...
Focal retrograde amnesia (FRA) is a rare neurocognitive disorder presenting with an isolated loss of retrograde memory. In the absence of detectable brain lesions, a differentiation of FRA from psychogenic causes is difficult. Here we report a case study of persisting FRA after an epileptic seizure. A thorough neuropsychological assessment confirmed severe retrograde memory deficits while anterograde memory abilities were completely normal. Neurological and psychiatric examination were unremarkable and high-resolution MRI showed no neuroradiologically apparent lesion. However, voxel-based morphometry (VBM)-comparing the MRI to an education-, age-and sex-matched control group (n = 20) disclosed distinct gray matter decreases in left temporopolar cortex and a region between right posterior parahippocampal and lingual cortex. Although the results of VBM-based comparisons between a single case and a healthy control group are generally susceptible to differences unrelated to the specific symptoms of the case

Jeremy was a guy everybody saw around, though most people didnt know him personally, he was still someone we all shook hands with and nodded to with a warm smile. Jeremy had attended a couple of Salsa classes with us and even hung out together at the bar after our groups winning at the National Salsa Competition, but none of us did know him well enough.. When the news came to us that he was slowly dying and losing his memory as a result of an inoperable cancer tumour in his brain, we were saddened and began to think, Jeremy isnt just the guy we know, he is our friend, and it hurt us so terribly that we might lose him and that he will no longer have a memory of our lives, or faint history as it may be..

Just casting about here, but wouldnt Propofol or a similar agent (if there is such a thing) additionally have an effect that from Joe and Dylans point of view would be advantageous; ie: amnesia. Though you use the word amnesia in the title of this post Im not seeing (or being obtuse and not seeing) the suggestion that Joe and or Dylan maybe initially banked on the amnesiatic (I am not sure if that is the correct form of that word, but "causing memory loss" is what I am talking about) properties of any of these drugs.. I think that in their delusion and malevolence these two men sought to incapacitate and sexually assault Robert and that they initially believed that the incapacitating drug would also produce amnesia in Robert.

RECOGNITION A recognition test differs from a recall test in that it provides the correct response embedded within a list of several other alternatives. The patient must choose the correct response from among these alternatives during a specified retrieval period. In other words, instead of having to try to recall the responses on his own, the patient is provided a set of responses from which to choose. The task could be either: 30 2. THE ORIGINAL MEMORY MODEL to select which responses he learned, or to tell which responses were originally paired with which stimuli, or to arrange the responses in a particular order. On the other hand, the amnesic patients recency performance was nearly normal. T h e ramifications of this outcome will be discussed in the next chapter, but it is important to note here that the only items that seemed to attain L T M status in the amnesics memory were the first one or two presented. In an attempt to determine at least one of the factors underlying alcoholic ...

Limbic encephalitis with antibodies to the voltage-gated potassium channel-complex (VGKC-LE) is now a well-established neurological syndrome. Recent work demonstrates many patients suffer from persisting anterograde amnesia following the resolution of VGKC-LE. However, no detailed assessment of retrograde memory, episodic or otherwise, has yet been undertaken. We assessed 14 VGKC-LE patients and 14 age-matched controls were assessed on a detailed measure of retrograde episodic memory (the Autobiographical Interview). One episodic memory was obtained from each decade of life (six in total). The results show that VGKC-LE patients had significant deficits in episodic recall across the most recent 40 years of their life, in the context of preserved personal semantic memory (as measured by the Autobiographical Memory Interview). Moreover, ultra-high field magnetic resonance imaging suggests that VGKC-LE is associated with focal hippocampal atrophy. These data demonstrate that retrograde amnesia is ...

Transient global amnesia is a sudden, temporary episode of memory loss that cant be attributed to a more common neurological condition, such as epilepsy or stroke.. During an episode of transient global amnesia, your recall of recent events simply vanishes, so you cant remember where you are or how you got there. In addition, you may not remember anything about whats happening in the here and now. Consequently, you may keep repeating the same questions because you dont remember the answers youve just been given. You may also draw a blank when asked to remember things that happened a day, a month or even a year ago.. With transient global amnesia, you do remember who you are, and recognize the people you know well. But that doesnt make your memory loss less disturbing.. Fortunately, transient global amnesia is rare, seemingly harmless and unlikely to happen again. Episodes are usually short-lived, and afterward your memory is fine..

Flunitrazepam is a sedative hypnotic benzodiazepine and has been shown to be one of the most effective at causing anterograde amnesia as compared in a dosage dependent manner to other benzodiazepines (see trials)[1]. Once taken, it has a very fast time frame of activation in its GABAnergic binding mechanisms; and the potent and rapid effect does not diminish its ability to last in the host for an, at least, average amount of time[2].Flunitrazepam, unlike other sedative hypnotic benzodiazepines, is able to, at higher doses, greatly affect psychomotor performance resulting in delayed reaction time an balance[3]. This effect is experienced in addition to the amnesiac effects that all benzodiazepines cause. The greater effect on psychomotor performance is thought to be attributed to the higher potency effects of Flunitrazepam as compared dose dependently to other benzodiazepines[3]. Flunitrazepams potency as a sedative hypnotic benzodiazepine is well documented but what cannot be under stressed is ...

We investigated the role of feedback processing in decision making under risk conditions in 50 patients with amnesia in the course of alcoholic Korsakoffs syndrome (KS). Half of the patients were administered the Game of Dice Task (GDT) and the remaining 25 patients were examined with a modified version of the GDT in which no feedback was provided. Patients results in the GDT and in the modified version were compared with that of 50 healthy subjects of whom 25 subjects performed the original GDT and 25 performed the modified version. While performance on the original GDT was superior to performance on the modified GDT in healthy subjects, KS patients performed similarly on both the GDT with and GDT without feedback. Performance on both task versions was correlated with categorization and set-shifting. The findings indicate that amnesic patients do not profit from receiving feedback for their decisions in explicit risk conditions. (C) 2008 Elsevier Inc. All rights reserved ...
Memory disturbances frequently occur after brain damage, but can be associated with psychiatric illnesses as well. Amnesia-the most severe form of memory impairment-has several variants, including anterograde and retrograde amnesia, material-specific and modality-specific amnesia, and transient global amnesia. We searched databases to obtain an overview of amnesia research from the past 5 years. Research into amnesia has increased exponentially, probably because of the availability of modern brain-imaging techniques. In line with the view that memory is not a unity but is organised into several systems, amnesia is described as a multifaceted disease with a frequently poor prognosis ...
A fugue state, formally dissociative fugue or psychogenic fugue (DSM-IV Dissociative Disorders 300.13), is a rare psychiatric disorder characterized by reversible amnesia for personal identity, including the memories, personality and other identifying characteristics of individuality. The state is usually short-lived (hours to days), but can last months or longer. Dissociative fugue usually involves unplanned travel or wandering, and is sometimes accompanied by the establishment of a new identity. After recovery from fugue, previous memories usually return intact, but there is complete amnesia for the fugue episode. Additionally, an episode is not characterized as a fugue if it can be related to the ingestion of psychotropic substances, to physical trauma, to a general medical condition, or to psychiatric conditions such as delirium, dementia, bipolar disorder or depression. Fugues are usually precipitated by a stressful episode, and upon recovery there may be amnesia for the original stressor ...
There are no laboratory tests that are necessary to confirm amnesia nor are there any physical conditions that must be met. However, it is very important not to overlook a physical illness that might mimic or contribute to amnesia. If there is any doubt about a medical problem, the mental health professional should refer to a physician, who will perform a complete physical examination and request any necessary laboratory tests.. Very sophisticated psychological testing, called neuropsychological testing, can be very helpful in determining the presence of amnesia. Sometimes the diagnosis of amnesia can be aided by the use of brain scans such as the magnetic resonance imaging (MRI).. via.

This type of amnesia is used as a plot element in the movie Eternal Sunshine of the Spotless Mind, in which a company (appropriately named Lacuna) offers the service of having a specific person erased from someones memories by removing all memories of them.. Similarly, in the manga Fruits Basket, the character Hatori Sohma has the ability to erase a persons memories. This ability is used by the head of the family, Akito, who instructed Hatori to use it when people outside the family discovered their secret. He also had to use the ability to make his fiancee, Kana, forget about him because hed caused her too much pain.. In the movie Heroes the protagonist Jack Dunne (Henry Winkler) learns a horrible truth about a friend of his about which he had known, but has forgotten.. In the BBC series Doctor Who, the character Donna Noble experiences amnesia of this sort when her memories are altered to remove any trace of the Doctor, aliens, or any sort of unearthly strangeness to prevent her mind from ...

Important points:. 1. Alcohol increases the risk for the following cancers: oral, larynx, pharynx, esophagus, liver, and lung. It may increase the risk for gastric, colon, pancreatic, and breast cancer.. I. Alcohol is the most common cause of cirrhosis and esophageal varices.. 3. Alcohol is involved in roughly 50% of fatal car accidents, 67% of drownings and homicides, 70-80% of deaths in fires, and 35% of suicides.. 4. Always give thiamine before glucose in an alcoholic; if you give them in the reverse order, you may precipitate Wernickes encephalopathy.. Wernickes vs. Korsakoffs syndromes. Wernickes syndrome - ophthalmoplegia, nystagmus, ataxia, and confusion; acute and often reversible; may be fatal. Korsakoffs syndrome = anterograde amnesia and confabulation, chronic and irreversible. Both are due to thiamine deficiency. The most likely cause is damage to the mamillary bodies and thalamic nuclei.. Alcohol withdrawal can be fatal. Treat on an inpatient basis. Use benzodiazepines ...
In this paper we present data from a closed head injury patient who presents a striking example of what Kapur (Cortex29, 217234, 1993) has termed "focal retrograde amnesia".

The data are discussed in relation to other reported instances of focal retrograde amnesia and a preliminary theoretical account is offered.. ...
Performance of patients with Korsakoffs syndrome and herpes encephalitis was compared on a retrograde amnesia (RA) test, asking subjects to recall and recognize the definitions of words that had come into the language at different time periods. Performance was also compared on a related test in which participants were asked to produce the words to definitions they were given in free recall and cued recall versions. It was hypothesized that, if the temporal gradient in remote memory results from a shift of information from episodic to semantic memory, then there should be a temporal gradient on these tasks, possibly steeper (i.e., greater relative sparing of early memories) in the patients in the Korsakoff group than in the herpes encephalitis group, who have widespread temporal lobe damage. Furthermore, in comparing semantic and episodic remote memory tests, consolidation theory would predict uniform temporal gradients across such tasks, whereas multiple trace theory would predict a ...
DM v Y City Council [2017] EWCOP 13, Bodey J, 15 June 2017. On a s 21A MCA 2005 application the court determined that it was in DMs best interests to remain in the current care home where he was forbidden to drink alcohol rather than move to a home that allowed the consumption of alcohol.. DM suffered from Korsakoffs Syndrome and lacked capacity to make decisions as to his care and residence and as to drinking alcohol. He needed support with all aspects of daily living. DM wished to drink alcohol. Expert evidence established that in view of his cirrhosis of the liver even if he were to drink a relatively low level of alcohol his life expectancy would be significantly reduced. The judge was referred to Aintree University Hospital NHS Foundation Trust v James [2013] UKSC 67 and Local Authority X v MM and Another [2007] EWHC 2003 including the passage in Munby Js judgment, "What good is making someone safe if it merely makes them miserable?".

The aim of this study was to further explore the basic mechanisms of the episodic memory search process. This included looking at the content of what was encoded and retrieved and the processes behind this encoding and retrieval. Some theories in the literature suggest that the LTM is more gist-based as item-specific information is lost soon after encoding, however, other theories have demonstrated that gist-based false recognition occurs because people are not retrieving the item-specific information effectively. The transfer appropriate processing theory explains that to successfully recall required information, retrieval processes need to match those of encoding. Jacoby and colleagues describe a retrieval process that involves constraining the memory search in such a way to re-enter the encoding context in order to retrieve the sought-for information. Using their memory-for-foils paradigm, this study investigates source-constrained retrieval using pictorial stimuli. It was hypothesised that for

Deficiency of nutrients such as minerals, proteins and vitamins are found in alcoholics. Low blood potassium, magnesium, calcium, zinc and phosphorus can occur in alcoholics. Vitamins like thiamine (B1), nicotinic acid (B3), pyridoxine (B6), folic acid, ascorbic acid (Yitamin C) and vitamin A may be deficient in alcoholics. Thiamine (B1) deficiency causes Wernickes and Korsakoffs syndrome.. Wernicke syndrome (= Wernicke disease or encephalopathy) is characterized by mental disturbance, paralysis of eye movements and ataxia (a loss of the power of muscular co-ordination) of gait (manner of or carriage in walking). Korsakoffs syndrome (= Korsakoffs psychosis) is characterised by confusion and severe impairment of memory, especially for recent events.. ...
Memories that have been "lost" as a result of amnesia can be recalled by activating brain cells with light. In a paper published today in the journal , researchers at MIT reveal that they were able to reactivate memories that could not otherwise be retrieved, using a technology known as optogenetics.. The finding answers a fiercely debated question in neuroscience as to the nature of amnesia, according to Susumu Tonegawa, the Picower Professor in MITs Department of Biology and director of the RIKEN-MIT Center at the Picower Institute for Learning and Memory, who directed the research by lead authors Tomas Ryan, Dheeraj Roy, and Michelle Pignatelli.. Neuroscience researchers have for many years debated whether retrograde amnesia -- which follows traumatic injury, stress, or diseases such as Alzheimers -- is caused by damage to specific brain cells, meaning a memory cannot be stored, or if access to that memory is somehow blocked, preventing its recall.. "The majority of researchers have favored ...

Objectives: This study investigated alterations in regional cerebral blood flow (rCBF) in patients with transient global amnesia (TGA) using statistical parametric mapping 99 (SPM99). Methods: Noninvasive rCBF measurements using 99mTc-ethyl cysteinate dimer (ECD) SPECT were performed on 8 patients with TGA who have ongoing symptoms and 17 age matched controls. The relative rCBF maps in patients with TGA and controls were compared. Results: In patients with TGA, significant decreased rCBF was found along the L superior temporal extending to L parietal region of the brain and L thalamus. There were areas of increased rCBF in the R temporal, R frontal region and R thalamus. Conclusion: We could demonstrate decreased perfusion in left cerebral hemisphere and increased perfusion in right cerebral hemisphere in patients with TGA using SPM99. The imbalanced change of rCBF between bilateral cerebral hemisphere in patients with TGA might suggest that imbalanced neuronal activity between the bilateral hemispheres

Morphines effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. Whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. The present study intended to investigate whether administration of morphine can change the expression level of rat hippocampal proteins during learning of a passive avoidance task. A step-through type passive avoidance task was used for the assessment of memory retention. To identify the complex pattern of protein expression induced by morphine, we compared rat hippocampal proteome either in morphine-induced amnesia or in state-dependent learning by two-dimensional gel electerophoresis and combined mass spectrometry (MS and MS/MS). Post-training administration of morphine decreased step-through latency. Pre-test administration of morphine induced state-dependent retrieval of the memory
