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.

Lack of evidence of acute ischemic tissue change in transient global amnesia on single-shot echo-planar diffusion-weighted MRI. (1/30)

BACKGROUND AND PURPOSE: There is uncertainty concerning the etiology of transient global amnesia (TGA). Previous CT and MRI studies have indicated that permanent structural abnormality is rare in TGA. Diffusion-weighted (DW) MRI is very sensitive to early ischemic parenchymal changes and has recently demonstrated embolic infarction in the posterior cerebral artery territory in 2 TGA patients. We report the findings of DW MRI in 8 patients in acute stages of TGA. METHODS: Conventional and echo-planar DW MRI was performed in 2 patients in the active phase and 6 patients in the recovery phase (1 to 8 hours after cessation of anterograde memory dysfunction) of spontaneously occurring TGA. RESULTS: None of the patients showed signs of hyperintensity on DW images or hypointensity on quantitative apparent diffusion coefficient (ADC) maps to suggest regional decreases of water mobility or acute T2 changes on transverse or coronal slices. CONCLUSIONS: We were unable to detect ADC or acute T2 changes with echo-planar DW MRI in patients with TGA, which suggests that mechanisms other than ischemic infarction may cause TGA. We did not identify spreading depression-associated changes of the ADC. Further refinement of MRI sequences may be necessary to detect subtle or transient signal change in brain parenchyma.  (+info)

Relationship between migraine and cardiac and pulmonary right-to-left shunts. (2/30)

A relationship between migraine with aura and the presence of right-to-left shunts has been reported in two studies. Right-to-left shunts are also associated with some forms of decompression illness. While conducting research in divers with decompression illness, it was our impression that divers with a large shunt often had a history of migraine with aura in everyday life and after dives. Therefore we routinely asked all divers about migraine symptoms. The medical records of the last 200 individuals referred for investigation of decompression illness were reviewed to determine the association between right-to-left shunts and migraine aura after diving, and migraine in daily life unconnected with diving. Migraine with aura in daily life unconnected with diving occurred significantly more frequently in individuals who had a large shunt which was present at rest (38 of 80; 47.5%) compared with those who had a shunt which was smaller or only seen after a Valsalva manoeuvre (four of 40; 10%) or those with no shunt (11 of 80; 13.8%) (P<0.001). Hemiplegic migraine occurred in 10 divers, each of whom had a shunt that was present at rest; in eight of these cases the shunt was large. The prevalence of migraine without aura was similar in all groups. Post-dive migraine aura was significantly more frequent in individuals who had a large shunt present at rest (21 of 80; 26.3%) compared with those who had a shunt that was smaller or only seen after a Valsalva manoeuvre (five of 40; 12.5%) or no shunt (one of 80; 1.3%) (P<0.001). Thus individuals with a large right-to-left shunt have an increased prevalence of migraine with aura in daily life unconnected with diving, and they also have an increased incidence of migraine aura after dives, but only when the dives liberate venous bubbles. These data suggest the possibility that, in some individuals, right-to-left shunts have a role in the aetiology of migraine with aura. The observations suggest that paradoxical gas embolism may precipitate migraine with aura.  (+info)

Contrast study on cognitive function with MRI and positron emission tomography imaging in transient global amnesia. (3/30)

OBJECTIVE: To study cognitive function and cerebral metabolic changes in patients with transient global amnesia (TGA). METHODS: Three patients with TGA were given mini-mental state examination (MMSE), revised Wechsler memory scale (WMS-R) examination and magnetic resonance imaging (MRI) scans after they had been diagnosed as TGA. Using (18)F labelled deoxyglucose as tracer, patients were given a positron emission tomography (PET) examination at different periods during recovery. RESULTS: No obvious abnormality was found in MMSE and MRI scans in the three patients. However, WMS-R examination and cerebral PET imaging displayed cognitive dysfunction of varying degrees and low metabolism in local areas related to memory in 2 of 3 patients. CONCLUSIONS: In TGA patients, cognitive function and cerebral metabolic levels are closely correlated with duration of symptoms. It is necessary to stop the TGA attack as quickly as possible early time.  (+info)

Working memory and executive functions in transient global amnesia. (4/30)

Transient global amnesia (TGA) is usually considered to produce a profound impairment of long-term episodic memory, while at the same time sparing working memory. However, this neuropsychological dissociation has rarely been examined in detail. While a few studies have assessed some components of working memory in TGA, the results that have been obtained are far from conclusive. To clarify this issue, we carried out a comprehensive investigation of working memory in 10 patients during a TGA attack. In the first study, we report the results from three patients examined with a battery of neuropsychological tests designed to assess each of the three subcomponents of Baddeley's model of working memory. In a second study, seven different patients underwent neuropsychological investigations that focused specifically on the central executive system, using a protocol derived from a study by Miyake and colleagues. Our findings showed that subcomponents of working memory, such as the phonological loop and visuo-spatial sketch pad, were spared in TGA patients. Specific executive functions that entailed inhibitory control, dual task performance, updating and shifting mechanisms were also found to be normal. However, we found significantly impaired performance for the Brown-Peterson test, and that TGA patients were significantly impaired in the recollection of their episodic memories. They also made reduced numbers of 'remember' compared with 'know' judgments in the episodic memory test several days after TGA. On the basis of our findings, it would appear that the episodic memory deficit during TGA is not related to elementary aspects of executive functioning. Our data also highlight the nature of the cognitive mechanisms involved in the Brown-Peterson task, which may well depend on long-term memory (such as the process of semantic encoding). Lastly, the selective deficit in recollective episodic memories observed in TGA may be principally related to medial temporal lobe abnormalities that have been reported in this syndrome.  (+info)

The dynamic time course of memory recovery in transient global amnesia. (5/30)

AIMS: To investigate the dynamic time course of transient global amnesia (TGA)--that is, the process of recovery and the interindividual variability--by testing four patients during the day of TGA itself (on three occasions) and at follow up (on two occasions). METHODS: A specially designed protocol focusing on semantic (both conceptual and autobiographical knowledge) and episodic (both anterograde and retrograde components) memory. RESULTS: Every patient showed marked impairment of both anterograde and retrograde episodic memory during the acute phase, with a relative preservation of personal and conceptual semantic knowledge. During the following phase, the authors observed similarities and differences among the patients' patterns of recovery. In general, retrograde amnesia recovered before the anterograde amnesia and anterograde episodic memory was recovered gradually in every case. In contrast, shrinkage of retrograde amnesia was more heterogeneous. In two of the patients, this shrinkage followed a chronological gradient and the most remote events were recovered first. In the two other patients, it depended more on the strength of the trace, and there was no temporal gradient. For the latter, an executive deficit could account for difficulties in accessing both conceptual knowledge and autobiographical memories. CONCLUSIONS: This profile of recovery suggests a "neocortical to medial temporal" process in every case, and the possibility of an additional frontal dysfunction in some cases. Hence, the acute phase seems to be characterised by a common episodic impairment. This variability between subjects appears in the recovery phase with two different patterns of impairment.  (+info)

Internal jugular vein valve incompetence and intracranial venous anatomy in transient global amnesia. (6/30)

BACKGROUND: Recently a causal relation between internal jugular vein valve incompetence (IJVVI) and transient global amnesia (TGA) has been suggested. IJVVI is postulated to provoke a transient mesiotemporal ischaemia by venous congestion. This mechanism requires a patent venous pathway from the affected IJV through the transverse sinus, confluens, straight sinus (SS), vein of Galen into the basal vein of Rosenthal and the internal cerebral veins. OBJECTIVE: To study IJVVI in TGA patients in relation to the intracranial venous anatomy. METHODS: IJVVI was defined if a repeated Valsalva manoeuvre (VM) led to a retrograde jugular flow detected by extracranial duplex ultrasound. Non-contrast venous MR angiography (MRA) was performed to analyse intracranial drainage patterns of the SS in relation to the side of the IJVVI. SS drainage was differentiated into three groups: predominantly right, left, and bilateral drainage. Ultrasound studies were performed in 25 TGA patients and 85 age matched controls. Twenty patients underwent venous MRA. RESULTS: Sixty eight per cent of patients and 33% of controls showed unilateral or bilateral IJVVI (p = 0.0025). In 36% of patients a TGA preceding VM was reported. Drainage pattern of SS and side of IJVVI corresponded in five of eight patients (63%) with VM and four of 12 patients without VM (33%, p = 0.0994). CONCLUSION: Our study confirms the significantly higher prevalence of IJVVI in TGA patients. However, no specific IJVVI related intracranial venous drainage patterns could be found to further support the hypothesis of a direct causal relation between IJVVI and TGA.  (+info)

What does transient global amnesia really mean? Review of the literature and thorough study of 142 cases. (7/30)

Since the first reports of transient global amnesia (TGA) were published in 1956, several neuropsychological and functional imaging studies have shed light on different aspects of this neurological syndrome. By establishing diagnostic criteria, Hodges and Warlow (1990b) have made it far easier to identify clinical TGA-related features. However, no comprehensive survey has been yet carried out in order to validate their criteria/findings or provide information about previously unknown features. In the present paper, (i) we review the literature published since Hodges and Warlow's study and seek to characterize the demographic and clinical features of TGA more accurately, (ii) we report 142 personal TGA cases, with supplementary information regarding both episodes and patients, such as precipitating events, associated symptoms and personality, and (iii) we suggest the existence of different groups of TGA patients, on the basis of a hierarchical cluster analysis. This revealed that in women, episodes are mainly associated with an emotional precipitating event, a history of anxiety and a pathological personality. In men, they occur more frequently after a physical precipitating event. In younger patients, a history of headaches may constitute an important risk factor. No link was found with vascular risk factors. The relevance of each of the above-mentioned variables is discussed in the light of our classification. An extensive description of cases from both the literature and our patient population allows us to refine the characterization of clinical TGA features.  (+info)

Selective affection of hippocampal CA-1 neurons in patients with transient global amnesia without long-term sequelae. (8/30)

The aetiology, pathomechanisms and anatomical correlates of transient global amnesia (TGA) still remain obscure. Recently, focal MR-signal diffusion-weighted imaging (DWI) changes in the hippocampus have been described in patients with TGA, but the exact localization, long term outcome and pathophysiological nature of these lesions still remain unknown. The topography and time course of hippocampal DWI lesions in 41 TGA patients was studied using serial 3 T high-resolution MR-imaging and correlated to clinical and neuropsychometric results. Of these, 29 patients showed 36 DWI lesions with corresponding T(2) lesions in the hippocampus within a time window of 48 h after onset. Almost all lesions (94%; 34/36) were selectively found in the CA-1 sector (Sommer sector) of the hippocampal cornu ammonis. Most DWI lesions (8/10) were already detectable in the peri-acute phase <6 h after onset of symptoms. A follow-up study 4-6 months after the episode did not show evidence for residual structural sequelae of these lesions (n = 20/20). A venous MR angiography of the intracranial dural sinus showed an asymmetric venous drainage in 21/24 (88%) patients. In 11/16 (69%) patients with unilateral lesions, the asymmetry corresponded to the side of the DWI lesion. Significant episodic verbal memory deficits in the acute phase (n = 14/18) were associated with lesions of the dominant hemisphere while impairment of visuospatial memory was associated with lesions of the non-dominant hemisphere. Persistent neuropsychological sequelae were not detected 4-6 months after the episode (n = 16). This is the first prospective study combining high-resolution imaging and neuropsychometry analysing the detailed functional anatomy and outcome of hippocampal DWI/T(2) lesions in TGA supporting the view the TGA being a benign transient disorder. The TGA can be considered a model for a focal transient perturbation of memory circuits in the temporo-mesial region.  (+info)

A patient who suffered a transient global amnesia (TGA) attack underwent regional cerebral blood flow (rCBF) SPECT imaging and neuropsychological testing in the acute phase, after one month and after one year. Neuropsychological testing in the acute phase showed a pattern of anterograde and retrograde amnesia, whereas memory was within age normal limits at follow up. SPECT data were analysed with a within subject comparison and also compared with those of a group of healthy controls. Within subject comparison between the one month follow up and the acute phase detected increases in rCBF in the hippocampus bilaterally; further rCBF increases in the right hippocampus were detected after one year. Compared to controls, significant hypoperfusion was found in the right precentral, cingulate and medial frontal gyri in the acute phase; after one month significant hypoperfusion was detected in the right precentral and cingulate gyri and the left postcentral gyrus; after one year no significant hypoperfusion
Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of TGA exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of consciousness, as well as deeply encoded facts of the individuals past, such as their own name. A person having an attack of TGA has almost no capacity to establish new memories, but generally appears otherwise mentally alert and lucid, possessing full knowledge of self-identity and identity of close family, and maintaining intact perceptual skills and a wide repertoire of complex learned behavior. The individual simply cannot recall anything that happened outside the last few minutes, while memory for more temporally distant events may or may not be largely intact. The degree of amnesia is profound, and, in the interval during which the individual is aware of his or ...
Dimethylsulfoxide (DMSO) is a solvent commonly used for the cryopreservation of autologous peripheral blood stem cells (APBSC). Side effects upon infusion of DMSO-cryopreserved APBSC mainly consist of nausea, emesis, chills, rigors, and cardiovascular events, such as bradyarrhythmia or hypotension.1-4 We report the first MRI documented case of transient global amnesia (TGA) that occurred in the setting of DMSO-cryopreserved APBSC infusion for a relapsing lymphoma.. A 30-year-old man, diagnosed with Hodgkins lymphoma, was admitted to our medical center for autologous peripheral blood stem cell transplantation. His history dates back to May 2006 when he presented with cervical, axillary and mediastinal lymphadenopathy associated with fever, chills, night sweats and weight loss. Pathological diagnosis was Hodgkins lymphoma. The patient was treated with 6 cycles of ABVD chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine) with complete remission in November 2006. He refused ...

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
Other international researchers, like Dr. Chung in Taiwan, were noting how internal jugular vein valve incompetence (IJVVI) affected by valsalva manuevers was related to transient global amnesia and hypoxic events. Dr. Zamboni, while utilizing ultrasound equipment and scanning the neck of an MS patient-- noted venous reflux. Something that was not normal, and had not been detected before--reflux in the absence of valsalva, independent of body position. He spent the next five years conducting blinded doppler studies, writing research, bringing other doctors on board and learning all he could about this disease mechanism. He tried to address the truncular venous malformations he found in MS patients veins with angioplasty. It helped his patients. And then he published his research, and I read it--along with patients, caretakers and doctors around the globe. ...

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 ...
An extensive body of literature has accrued on the imaging of the human hippocampus since it was first visualized clearly in a living person using magnetic resonance imaging (MRI) in the late 1980s. Clinicians now routinely perform high-resolution MRI to inspect the structure of the hippocampus and surrounding cortices in detail in patients suspected of having Alzheimers disease (AD) and related disorders, temporal lobe epilepsy and related conditions, or limbic encephalitis, transient global amnesia, or other forms of amnesia. Researchers have developed protocols for measuring the size of the hippocampus and are now working toward visualization and measurement of hippocampus subfields in vivo. Investigators are also using advanced imaging techniques to measure hippocampal activity during memory and other tasks as well as its perfusion, metabolism, and molecular constituents. New technical advances in imaging continue to be applied to the investigation of the hippocampus, medial temporal ...

The extracranial venous system is complex and variable between individuals. Until recently, these variations were acknowledged as developmental variants and were not considered pathological findings. However, in the last decade, the presence and severity of uni- or bi-lateral jugular venous reflux have been linked to several central nervous system (CNS) disorders such as transient global amnesia, transient monocular blindness, cough headache, primary exertional headache and most recently to Alzheimers disease. The most recent introduction of a composite criteria-based vascular condition named chronic cerebrospinal venous insufficiency (CCSVI) that was originally linked to multiple sclerosis increased the interest in better understanding of the role of the extracranial venous system in the pathophysiology of CNS disorders. The ultimate cause-consequence relationship between these conditions and CNS disorders has not been firmly established and further research is needed. This article collection ...

C57BL/6 mice exhibit acute transient decreases in lung conductance (GL) and dynamic compliance (Cdyn) after intravenous administration of serotonin (5-HT). To identify the specific agonist receptor subtypes responsible for this bronchoconstriction, we measured changes in pulmonary function in C57BL/6 mice in response to intravenous infusion of 5-HT receptor subtype-selective agonists and to 5-HT in the presence of antagonists selective for the 5-HT2 or 5-HT3 receptor subtypes. Agonists selective for the 5-HT1A/1B/1D or 5-HT3 receptor subtypes induced minimal or undetectable pulmonary responses, whereas infusion of alpha-methyl-5-hydroxytryptamine, a 5-HT2 receptor-selective agonist, led to dose-related decreases in Cdyn and GL. The selective 5-HT3 receptor antagonist, LY278584 maleate, (1.0 mg/kg i.v.) caused no detectable reduction in the response to 100 micrograms/kg of 5-HT. In contrast, treatment with the 5-HT2 receptor antagonist LY53857 (10 micrograms/kg i.v.) resulted in a significant ...

Popular models of long-term memory (LTM) organization in the brain suggest that the hippocampus (HPC) has a specific, unique role in LTM. Authors of popular theories highlight specific patterns of amnesia when the HPC is damaged before a learning event. However, these views also suggest that HPC damage should have equivalent amnestic effects if disrupted before or soon after a learning event. By contrast to this prediction, several groups have shown that HPC damage after learning causes more widespread, or "global" amnesia. This general effect remains without explanation in popular models of HPC function in LTM. Here, I suggest a new concept, on long-term memory organization to account for these effects and generate several new predictions. In recent work, we have begun to confirm some of these predictions, supporting a general role of the HPC in LTM organization.. ...
This is a randomized, controlled, prospective trial on the safety of physical training in TGA patients after atrial switch operation.. In transposition patients after atrial switch operation, the morphological right ventricle serves as the systemic ventricle. These patients often develop signs of heart failure. It is not known, whether physical training can safely be recommended in these patients- like heart failure guidelines recommend training in patients with normal anatomy. Furthermore it is not known, whether these TGA-patients benefit from training with respect to cardiopulmonary exercise capacity.. Primary endpoints are Systemic Ventricle Ejection Fraction and Volumes, Exercise Capacity.. Secondary endpoints are Echo Diastolic Function, as well as laboratory markers of heart failure. ...
Hi Suzi:. Nice to meet you but under unfortunate circumstances.. I think the flashbacks lessen as time goes on. But, it is very important to deal with this now. If you deal with the flashbacks now, as in counseling, then you will work thru this much quicker and easier. You can also go with self-help books, but with flashbacks it is sometimes to much to bear without help.. I have been completely away from my abuser for 2 years now and I have had nightmares as recently as just a couple nights ago, but have had things brought up lately.. Alot of dealing w/ these is to stop and take a break when you have them. If sleeping, get up and walk around a bit, listen to music. If doing daily tasks then switch to something else. If they are unpredictible and coming more frequently, then please seek counseling.. ...

The ability to learn to criterion a visually-guided stylus maze was found impaired in patients with right posterior cerebral damage, not only in comparison with controls but also with other hemisphere-damaged groups. The contribution of the corresponding left sided area to this task is dubious, and certainly not substantial. This finding points to the independent organisation of long-term spatial memory in the right posterior cerebral cortex, an inference that was further supported by the study of two cases. The first was a female patient with right temporo-parietal softening (as suggested by clinical, EEG, and brain scan data) who showed topographical amnesia and inability to learn the visual maze over 275 trials. On an extensive battery of tests she was found free from disorders of space perception, and from verbal and visual memory impairment. The second was a patient presenting with severe global amnesia who, nevertheless, had no difficulty in route finding, and reached the criterion on the ...

Homoeopathy provides several suitable remedies for the treatment of acute synovitis, including Drosera rotundifolia. This remedy has antispasmodic and analgesic properties, and is an ideal solution for the treatment of joint disorders. The recommended dosage consists of 5 granules of Drosera Rotundifolia 7 CH or 9 CH, of which two daily intakes are required over the course of one week. However, it is important to follow some rules during this treatment, including refraining from consuming stimulants such as coffee or mint, as well as taking the remedy outside of meals. The use of Ferrum phosphoricum is also indicated to relieve irritable hips. This remedy, developed from a chemical strain, is highly effective for reducing pain that is characteristic of acute synovitis. The dosage consists of 5 granules of Ferrum phosphoricum 5 CH, to be taken three times a day for the duration of one week. In addition, this remedy may be used in combination with a similar dosage of Drosera Rotundifolia 5 ...
RIVISTA SPERIMENTALE DI FRENIATRIA - Amnesia dissociativa e trauma: una prospettiva secondo la teoria della dissociazione strutturale ( Nel DSM-IV lamnesia dissociativa è considerata unentità clinica distinta che può prendere le seguenti forme: amnesia localizzata, amnesia continua, amnesia sistematizzata, amnesia generalizzata e amnesia selettiva. In ambito clinico, tuttavia, essa è più comunemente presente come espressione sintomatica di disturbi più complessi ed estesi, soprattutto i disturbi dissociativi complessi (e spesso in pazienti che hanno subito traumi acuti e cronici). La dissociazione è il risultato di unintegrazione difettosa, che di solito si produce in occasione di esperienze traumatiche, di quei sistemi neuro-bio-psicologici dalla struttura estremamente complessa costituita dalla personalità. Questo difetto comporta una dissociazione della personalità in due o più parti scisse - sottosistemi dinamici e attivi, ma rigidi e relativamente chiusi. In base a questo approccio

BACKGROUND AND PURPOSE: Many previous studies on dementia in stroke have restrictive inclusion criteria, which may result in underestimation of dementia rates. We undertook a large prospective population-based study of all transient ischemic attack and stroke to determine the impact of study entry criteria on measured rates of pre- and postevent dementia. METHODS: All patients with acute transient ischemic attack or stroke from a defined population of 92 728 are referred from primary care or at hospital admission to the Oxford Vascular Study (2002-2007) and have baseline clinical and cognitive assessment and follow-up. We examined the impact of early death, other nonavailability, and commonly used selection criteria, on measured rates of dementia. RESULTS: Among 1236 patients (mean age/SD 75.2/12.1 years, 582 men, 403 transient ischemic attack), 139 died or were otherwise unavailable for baseline assessment, 319 had prior dependency, 425 had comorbidity, 512 were aged ≥80 years, 85 were dysphasic, and
