Results Among patients with MCI, greater severity of depressive symptoms was associated with greater global cognitive impairment, with a moderate effect size. A mediation analysis revealed that patients with MCI experiencing depressive symptoms may exhibit global cognitive impairment because their depressive symptoms were reducing their capacity for working memory, episodic memory and non-speed-based executive functions. A moderation analysis indicated that this effect was consistent across age, gender, years of education and APOE-e4 status for working memory and episodic memory, and was observed in patients with MCI older than 65 years for executive functions. In cognitively normal elderly adults and patients with AD, depressive symptoms were not associated with global cognitive impairment. ...
U.S., March 20 -- ClinicalTrials.gov registry received information related to the study (NCT03081429) titled A Prospective Cohort Study of Perioperative Covert Stroke and Postoperative Cognitive Dysfunction on March 10. Brief Summary: With the development of population aging, the incidence of covert stroke and cognitive dysfunction gradually increased. Currently, there is still lack of prospective cohort study with large sample size on the relationship between perioperative covert stroke and postoperative cognitive dysfunction. The investigators will perform a prospective cohort study. The aim of the study is to determine whether there is an association between perioperative covert stroke and postoperative cognitive dysfunction in elderly patients undergoing noncardiac surgery.

This study aimed to assess the relationship between renal impairment and cognitive decline. Of the 3769 patients, 396 (10%) had cognitive impairment at the outset. After the 2-year follow-up, 194 participants (6.2%) developed new cognitive impairment. Multiple logistic regression analysis showed that moderate-to-severe impaired renal function was associated with incident cognitive impairment after 2 years in a large cohort of elderly subjects ...
Objective: Mini-mental state examination, a nonspecific measure of global cognitive function, and the clock drawing test, a very concise and specific measure of cognitive function, are among the most widely used screening tests for cognitive dysfunction. The present research aimed to examine the correspondence between MMSE and CDT scores. Methods: A total of ...
Objective: To use functional MRI )fMRI) to investigate whether hippocampal activation during a memory task can predict cognitive decline in individuals with mild cognitive impairment (MCI). Methods: 25 older individuals with MCI performed a visual scene encoding task during fMRI scanning, and were followed clinically for at least 4 years after scanning. A hypothesis driven analysis of fMRI data was performed. First, fMRI data were analysed at the group level to identify the regions of the hippocampal formation that were engaged by this memory task. Parameter estimates of each subjects memory related hippocampal activation )% signal change) were extracted and were analysed with a linear regression model to determine whether hippocampal activation predicted the degree or rate of cognitive decline, as measured by change in Clinical Dementia Rating Sum-of-Boxes )CDR-SB). Results: Over 5.9 (1.2) years of follow-up after scanning, subjects varied widely in degree and rate of cognitive decline (change ...

Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from a few days to a few weeks after surgery. In rare cases, this disorder may persist for several months after major surgery. POCD is distinct from emergence delirium. It occurs most commonly in older patients and those with pre-existing cognitive impairment. The causes of POCD are not understood. It does not appear to be caused by lack of oxygen or impaired blood flow to the brain and is equally likely under regional and general anesthesia. It may be mediated by the bodys inflammatory response to surgery. POCD is common after cardiac surgery, and recent studies have now verified that POCD also exists after major non-cardiac surgery, although at a lower incidence. The risk of POCD increases with age, and the type of surgery is also important because there is a very low incidence associated with minor surgery. POCD is common in adult patients of all ages at ...
TY - JOUR. T1 - Subjective cognitive complaints and objective cognitive impairment in parkinsons disease. AU - Hong, Jin Yong. AU - Lee, Yoonju. AU - Sunwoo, Mun Kyung. AU - Sohn, Young H.. AU - Lee, Phil Hyu. PY - 2018/1. Y1 - 2018/1. N2 - Background and Purpose Subjective cognitive complaints (SCCs) are very common in patients with Parkinsons disease (PD). However, the relationship between SCCs and objective cognitive impairment is still unclear. This study aimed to determine whether SCCs are correlated with objective cognitive performance in patients with PD. Methods Totals of 148 cognitively normal patients, 71 patients with mild cognitive impairment (MCI), and 31 demented patients were recruited consecutively from a movement-disor-ders clinic. Their SCCs and cognitive performances were evaluated using the Cognitive Complaints Interview (CCI) and a comprehensive neuropsychological battery. Results The CCI score increased with age, duration of PD, and depression score, and was inversely ...
Major surgeries, such as cardiac or orthopaedic procedures in particular, expose the patient to extensive trauma, blood loss, and tissue injury; all of these factors effectively modulate the immune system to ultimately trigger an inflammatory response. Postoperative cognitive dysfunction (POCD), the condition being characterized by impairment of short and long-term memory, is one of common complicates following surgery. Recently, our data have demonstrated that neuroinflammation and microglia activation in the hippocampus following surgery are associated with cognitive decline. The aim of this thesis is to investigate the inflammatory signaling pathways specifically involved with POCD, with a particular interest between systemic inflammation and local inflammation in the brain following surgery. The data presented in this thesis introduce the general concepts and the involvement of inflammation in the etiology of cognitive dysfunctions using a mouse model of POCD. Upon the identification of ...
Objective : Performance validity tests (PVTs) are essential in neuropsychological evaluations; however, it has been questioned how PVTs function in the context of cognitive impairment, and whether cognitive impairment alone is sufficient to cause PVT failure. Further, there is concern that some clinicians will disregard failed PVTs due to their perception that failures represent false-positive errors secondary to cognitive impairment. This study examined patterns associated with cognitively impaired versus noncredible performance across a battery of PVTs and neuropsychological tests. Additionally, the impact of VA service-connection and disability-seeking status on test validity was investigated. Method : A mixed-clinical sample of 103 veterans were administered six PVTs and neuropsychological tests. Performance was compared across three groups: valid-cognitively unimpaired, valid-cognitively impaired, and noncredible. Results : Significant PVT score differences and failure rates emerged across ...

Improving psychological well-being and cognitive health is now listed as the priority on the healthy aging agenda. Depression and cognitive impairment are great challenges for the elderly population. There have been numerous studies on depression and cognitive impairment and dementia. However, the neural correlates of depression and cognitive impairment have not yet been elucidated. With the development of neuroscience and relevant technologies, studies on anatomical and functional neural networks, neurobiological mechanisms of mood and cognition in old age will provide more insight into the potential diagnosis, prevention and intervention in depression and cognitive impairment. For example, longitudinal neuroimaging studies depicting the trajectories of patterns of structural and functional brain networks of mild cognitive impairment may provide potential imaging markers for the onset of dementia.Population-based studies have addressed the potential interaction between mood and cognitive impairment in
In this prospective cohort study of black and white adults in the United States aged 45 and older, free of stroke and baseline cognitive impairment, mid-range to high Lifes Simple 7 scores at baseline were associated with lower incidence of clinically relevant cognitive impairment on a 3-test measure of verbal learning, memory, and fluency. Rather than a dose-response pattern across the range of Lifes Simple 7 scores, we observed that associations with ICI were the same for the highest tertile of Lifes Simple 7 score and the middle tertile, relative to the lowest tertile. This pattern suggests that even intermediate levels of CVH are preferable to low levels of CVH. This is an encouraging message for population health promotion, because intermediate CVH is a more realistic target than ideal CVH for many individuals.. The purpose of the Lifes Simple 7 metric is to summarize several modifiable factors into a single score to promote and measure individual- and population-level improvements in ...

Presbycusis-related tinnitus and cognitive impairment are common in the elderly and generate a massive burden on family and society. Except for age, the study explored the gender differences in the prevalence of the three diseases. We found that women have an advantage in maintaining better cognitive and auditory functions. Recent studies suggest the complex links among the three diseases. Peripheral hearing loss can affect sound coding and neural plasticity, which will lead to cognitive impairment and tinnitus. The deficits of the central nervous system, especially central auditory structures, can, in turn, cause the presbycusis. The interaction among three diseases indicated that comprehensive assessment, intervention and treatment in consideration of hearing loss, tinnitus and cognitive impairment are important to decay aging.
Author(s): Simon, Tony J; Wu, Zhongle; Avants, Brian; Zhang, Hui; Gee, James C; Stebbins, Glenn T | Abstract: BACKGROUND:Chromosome 22q11.2 deletion syndrome is one of the most common genetic causes of cognitive impairment and developmental disability yet little is known about the neural bases of those challenges. Here we expand upon our previous neurocognitive studies by specifically investigating the hypothesis that changes in neural connectivity relate to cognitive impairment in children with the disorder. METHODS:Whole brain analyses of multiple measures computed from diffusion tensor image data acquired from the brains of children with the disorder and typically developing controls. We also correlated diffusion tensor data with performance on a visuospatial cognitive task that taps spatial attention. RESULTS:Analyses revealed four common clusters, in the parietal and frontal lobes, that showed complementary patterns of connectivity in children with the deletion and typical controls. We interpreted
VP/VLBW individuals had significantly lower IQ scores than term-born individuals across all time points into adulthood. Approximately 1 in 4 VP/VLBW adults had a severe cognitive impairment and mean differences between VP/VLBW and term-born individuals in IQ scores were partly explained by those with cognitive impairment. IQ scores were consistently found to be more stable from childhood to adulthood in VP/VLBW than term-born individuals, yet this difference in stability disappeared when individuals with severe cognitive impairment in adulthood were excluded. Cognitive function in adulthood could be fairly well estimated from age 6 years in term-born children and already from age 20 months in VP/VLBW children. IQ scores were highly stable in VP/VLBW individuals who had cognitive impairment in adulthood.. VP/VLBW children are known to be at risk for neurodevelopmental problems, including cognitive impairment and higher risk of lower educational qualifications in young adulthood compared with ...
Type 2 diabetes mellitus (DM2) is associated with moderate cognitive impairment in verbal memory, mental flexibility, and information processing speed, while other cognitive functions remain relatively unaffected.1 Moreover, epidemiological studies have shown that DM2 patients have a twofold increased risk of developing either vascular dementia or Alzheimers disease.1,2 In the present study we examined whether mild cognitive impairment (MCI) and "cognitive impairment, no dementia" (CIND)-two concepts that are used to describe cognitive impairment in the transitional state between normal aging and early dementia-can be applied to the cognitive impairments encountered in a population based sample of DM2 patients. Recently, these concepts have attracted considerable attention, as individuals who meet the criteria for either MCI or CIND are known to have a substantially increased risk of developing dementia.3,4 MCI is defined as a memory deficit without impairments in other cognitive domains.3 ...
The incidence of severe forms of HIV-associated neuorcognitive disorders, or HAND, has declined significantly with the availability of combination antiretroviral drug therapy over the last 20 years.. But the prevalence of the milder form has remained stable and even slightly increased, affecting 50 to 60 per cent of people living with HIV and AIDS.. "Screening tools have not been updated to reflect this change," said Dr. Sean B. Rourke, a neuropsychologist who heads the Neurobehavioural Research Unit at St. Michaels. "We are still trying to use or adapt the older dementia screening tools to catch the milder form of HAND.". Dr. Rourke said that having effective screening tests to identify and differentiate the two different forms of HAND is important for treatment decision-making. The current standards of practice requires a detailed neuropsychological examination, which is time-consuming and not readily accessible.. "Identifying that patients have a mild form of this condition is critical," ...
Given the aging population and the corresponding increase in the incidence of AD, information on the prognosis of AD will help practitioners and unpaid caregivers to better meet the needs of patients with AD.. This well designed, prospective study by Larson et al provides estimates of survival after initial diagnosis of AD. Estimated survival rates were longer than those reported by the Canadian Study of Health and Aging (3.2 y for men and 3.4 y for women).1 This difference may be attributed to the older sample in the Canadian Study of Health and Aging.. Length of survival after onset of AD may be quite different from length of survival after initial diagnosis. Identifying the precise onset of AD may be difficult because of the insidious nature of the disease, unpaid caregivers lack of awareness of changes in cognition and functional abilities, and the patients ability to compensate for impairments. Although diagnosis at the onset of disease may not alter the natural course of AD, it could ...

Although the Seattle Longitudinal Study was designed to focus on cognitive changes in normal community-dwelling populations, it is inevitable that a prospective study of aging will eventually include in its successive follow-up cycles individuals who are beginning to show cognitive impairment and eventually may develop full-blown symptoms of dementia. This chapter reports some initial findings on the apolipoprotein E genetic marker of dementia as it relates to cognitive decline. Studies involving the neuropsychological assessment of a community-dwelling sample of older adults who have not previously been identified as suffering from cognitive impairment are described, along with the extension analyses that link the clinical measures with the psychometric battery for the study of normal aging. The chapter ends by analyzing studies that obtain postdicted estimates of earlier performance on the neuropsychological measures and speak to the possibility of early detection of risk for cognitive ...

Results:. The mean age of the patients was 80 years; 68% of patients were women. Patients with six or more depressive symptoms had greater comorbid illness, functional impairment, and cognitive impairment at admission than patients with fewer depressive symptoms. Three-year mortality was higher in patients with six or more depressive symptoms (56% compared with 40%; hazard ratio, 1.56 [95% CI, 1.22 to 2.00]; P , 0.001). After adjustment for age, acute illness severity, comorbid illness, functional impairment, and cognitive impairment at the time of admission, patients with six or more depressive symptoms continued to have a higher mortality rate during the 3 years after admission (hazard ratio, 1.34 [CI, 1.03 to 1.73]). Although depressive symptoms contributed less to the mortality rate than did the total burden of comorbid medical illnesses, the excess mortality rate associated with depressive symptoms was greater than that conferred by one additional comorbid medical condition. ...
The classification of neurodegenerative disorders is based on the major component of the protein aggregates in the brain. The most common altered proteins associated with neurodegeneration are Hyperphosphorylated tau (HPt), beta amyloid (Aβ), alpha-synclein (αS) and transactive response DNA binding protein 43 (TDP43). In this study we assessed the incidence and the neuroanatomical distribution of proteins associated with neurodegeneration in the brain tissue of cognitively unimpaired subjects.. We demonstrated the early involvement of the Locus Coeruleus (LC) with HPt pathology in cognitively unimpaired mid aged subjects, a finding which supports the notion that LC is an initiation site of HPt pathology. This may suggest that development of clinical assessment techniques and radiological investigations reflecting early LC alterations may help in identifying subjects with early stages of neurodegeneration.. Furthermore, we studied a large cohort of cognitively unimpaired subjects with age at ...
welcome to the forum! i agree that one of the most frustrating parts of this dd is the problem with cognitive functions. i am currently working towards my bachelors in accounting and have definitely seen a decline in my ability to remember information. i have had to fall back on notes, notes, notes! i have notes in a couple of different places regarding when everything is due-in my planner, on my dry erase board, sticky notes on my computer-and that seems to really have helped me get things done on time. with regards to remembering important information, ive started relating information i need to know to other things..little tips or jingles or small poems or whatever that contains the information i need to remember and that has really helped, too. also, i take all of my classes online (which is very helpful!) and NEVER do homework or take a test if im in a lot of pain or overly tired or hungry. if youre taking in person classes then you obviously dont have the freedom of flexibility that ...
Retention of certain metabolites in the blood may contribute to cognitive impairment in patients with kidney failure, revealed a new study.
Cognitive dysfunction can make a person feel hopeless, and they may turn to unfortunate sources in an effort to regain some control over their mental state. Commonly abused substances include alcohol, illegal narcotics and prescription drugs. Stimulants are a commonly abused drug for those who are dealing with cognitive issues that impair the sharpness of their mental processes. It is also possible to become addicted to legitimately prescribed medication that was initially aimed at treating a cognitive disorder. Individuals with cognitive impairment may become dependent on their medications and suffer withdrawal if they attempt to get off them without proper medical supervision.. If you or a loved one is addicted to medication for a cognitive disorder, help is available. Call our 24/7 hotline at 1-888-997-3147 for information on how you can get free of your addiction while managing the symptoms of your cognitive disorder.. ...
Multivariable repeated measures regression analysis identified three independent predictors of NPZ-3 worsening during follow-up ranging from 2 to 9 years (median 6): More years since entering the parent study (and thus more years on ART) and a time-varying CD4 count above 350 (versus below) protected against neurocognitive decline. Compared with a nadir CD4 count below 51, a nadir of 51 to 200 or above 200 tended to protect against decline, but those associations fell short of statistical significance. Among comorbidity risk factors, only a history of stroke independently raised the odds of declining NPZ-3 score. In a nonsignificant association, injection drug use tended to boost odds of worsening neurocognitive function ...
Results A total of 12,336 participants (baseline age 56.8 [5.7], 21% black, 56% women) were included. After adjusting for demographic variables, vascular risk factors, and comorbidities, each standard deviation (SD) increase in midlife inflammation composite score was associated with an additional 20-year decline of −0.035 SD (95% confidence interval: −0.062 to −0.007) on the cognitive composite score. We found a similar association between each SD increase in midlife CRP level and additional 20-year cognitive decline (−0.038 SD, 95% confidence interval: −0.057 to −0.019). Participants with a midlife inflammation composite score in the top quartile had a 7.8% steeper cognitive decline, compared to participants in the lowest quartile; CRP in the top quartile was associated with an 11.6% steeper cognitive decline. In cognitive domain-specific analyses, elevated midlife inflammatory markers were most consistently associated with declines in memory. Results were similar after adjusting ...

March 18, 2014 - Brain imaging using nuclear imaging radiotracers can detect early evidence of Alzheimers disease that may predict future cognitive decline among adults with mild or no cognitive impairment. This is according to a 36-month follow-up study led by Duke Medicine.. The national, multicenter study confirms earlier findings suggesting that identifying silent beta-amyloid plaque build-up in the brain could help guide care and treatment decisions for patients at risk for Alzheimers. The findings appeared online March 11, 2014, in Molecular Psychiatry, a Nature Publishing Group journal.. "Our research found that healthy adults and those with mild memory loss who have a positive scan for these plaques have a much faster rate of decline on memory, language and reasoning over three years," said lead author P. Murali Doraiswamy, M.D., professor of psychiatry and director of the neurocognitive disorders program at Duke.. Alzheimers disease - which currently has no cure - afflicts an ...
Evidence suggests that diabetes is a risk factor for Alzheimer disease. But how does it affect those who already have AD? The results of a large, prospective French study, released in todays Neurology, may seem counterintuitive. Writing for the REAL.FR study group, Caroline Sanz, Inserm U558, Toulouse, France, and colleagues report slower cognitive decline over a four-year period in AD patients with diabetes mellitus (DM) compared to AD patients without diabetes. The difference was apparent even after adjusting for confounding variables, such as prescription diabetes medication, and the results confirm similar findings reported in smaller studies (see Mielke et al., 2007).. Before the study, the researchers hypothesized that diabetes would accelerate cognitive decline, and they suggest several plausible explanations for the unexpected results. DM patients receive more medications, such as anti-hypertension drugs, for example, that might protect against cardiovascular risks for cognitive ...

People with cognitive impairment are significantly more likely to have a stroke, with a 39% increased risk, than individuals with normal cognitive function.
Currently, 5 million Americans age 65 and up are actively suffering from dementia, a syndrome characterized by significant cognitive impairment - at a cost of $203 billion per year, which doesnt include the 17.5 billion hours of unpaid care from caregivers. Dementia (the original Latin word for madness) encompasses both short and long-term memory loss but also includes dramatic changes in personality as well as behaviors that are difficult to handle. This often surprises people given that they dont expect their well-mannered elderly relatives to act petulantly or unreasonably. Furthermore, caregivers bear a large burden because basic life-sustaining skills, such as eating and going to the bathroom, are no longer routine for the affected people. In addition to the living-assistance these patients require, the cost of taking care of a demented patient can reach exorbitant sums which are unaffordable for many families. Dementia is not a curable disease so its exigent conditions demand that we ...
To characterize cognitive function over time, while minimizing potential redundancy in the cognitive measures, a factor analysis was performed on the 14 cognitive test scores from baseline. We chose a five-factor solution, which represents 5 cognitive domains: structured verbal memory, unstructured verbal memory, executive function, visual memory and attention/concentration. To quantify overall cognitive function, a baseline cognitive index was first calculated as the mean of the 5 preoperative domain scores. The cognitive index score has a mean of zero, thus any positive score is above the mean, any negative score is below the mean. A continuous change score was then calculated by subtracting the baseline from the 6-week cognitive index. The resulting outcome measure is unbounded with standard deviation of 0.35. A negative change score indicating decline and a positive score indicating improvement ...
Memory problems in those with mild cognitive impairment may begin with problems in visual discrimination and vulnerability to interference - a hopeful discovery in that interventions to improve discriminability and reduce interference may have a flow-on effect to cognition.. The study compared the performance on a complex object discrimination task of 7 patients diagnosed with amnestic MCI, 10 older adults considered to be at risk for MCI (because of their scores on a cognitive test), and 19 age-matched controls. The task involved the side-by-side comparison of images of objects, with participants required to say, within 15 seconds, whether the two objects were the same or different.. In the high-interference condition, the objects were blob-like and presented as black and white line-drawings, with some comparison pairs identical, while others only varied slightly in either shape or fill pattern. Objects were rotated to discourage a simple feature-matching strategy. In the low-interference ...
Results Of 205 articles identified in the search, 17 studies on 2725 patients (grand mean age 67 years; mean age range 61-71 years) with follow-up periods of 1 day to 4 years (median 7 days; IQR 1-68 days) were included. Studies focused almost exclusively on hypercholesterolaemia as a measure of dyslipidaemia and on statins as lipid-lowering treatment. Across 12 studies on hypercholesterolaemia, we found no association with POCD risk (RR 0.93; 95% CI 0.80 to 1.08; P=0.34). Statin use before surgery was associated with a reduced POCD risk across eight studies (RR 0.81; 95% CI 0.67 to 0.98; P=0.03), but data on treatment duration were lacking. ...

Normal aging is associated with declines in several cognitive domains, most notably episodic memory and executive functions (for reviews, see [1-4]). These cognitive deficits are associated with myriad brain changes, including structural and functional deterioration of prefrontal, basal ganglia, and medial temporal areas and their interconnections. However, establishing a link between these changes and cognitive decline in normal aging has proven surprisingly difficult [2, 5].. Alterations in two classic neurotransmitter systems have drawn considerable attention in cognitive aging: dopamine [6] and acetylcholine. For decades, acetylcholine (ACh) was thought of primarily as a memory-related neurotransmitter, but this view has recently been revised, with ACh now thought to play an equally if not more crucial role in executive functions (for reviews, see [7-9]). The integrity of cortical cholinergic inputs appears to be critical for modulating attention, by enhancing responsiveness to sensory ...

The degeneration of a small, wishbone-shaped structure deep inside the brain may provide the earliest clues to future cognitive decline, long before healthy older people exhibit clinical symptoms of memory loss or dementia, a study by researchers at the UC Davis Alzheimers Disease Center has found.
This study will assess the effects of each of the two therapies given separately, both targeting amyloid, on cognition, global clinical status, and underlying pathology in participants at risk for the onset of clinical symptoms of Alzheimers disease (AD). Cognitively unimpaired individuals with two APOE4 genes and age 60 to 75 years, inclusive, are selected as they represent a population at particularly high risk of progression to Mild Cognitive Impairment and/or dementia due to Alzheimers disease.. The study follows a randomized, double-blind, placebo-controlled, two-cohort, parallel group design in which participants receive one of the investigational treatments or their matching placebo for at least 60 months up to a maximum of 96 months and no longer than when the target number of events for the TTE endpoint has been observed and confirmed in either cohort.. An unbalanced randomization (active: placebo) of 5:3 ratio in Cohort I (430 CAD106 :260 Placebo) and 3:2 ratio in Cohort II (390 ...
Researchers have discovered a key protein linked to Alzheimers, inhibition of which could prevent the neuronal damage and subsequent cognitive decline associated with the disease.
Following a brain injury (e.g. a stroke), people often experience a range of cognitive problems in addition to any difficulties in motor function. These cognitive problems may include change in language ability, in memory, in the ability to respond to the environment (through words or action), or to think through problems, including problems with maths and money handling.. Cognitive problems strongly influence how well people functionally recover after a stroke. Currently patients are not routinely screened to detect these cognitive problems. The Birmingham Cognitive Screen (BCoS™) is a new test instrument developed to enable the comprehensive and efficient screening of post-stroke cognitive function by health professionals. Within the hour test the examiner gains an overview of a range of cognitive processes in the stroke survivor. BCoS™ has been designed to be aphasic and neglect friendly, i.e. to overcome the difficulties in assessing individuals with speech and/or visuo-spatial ...

Table 2: Predictors of Cognitive Decline in the Early Stages of Parkinsons Disease: A Brief Cognitive Assessment Longitudinal Study
The treatment of pain begins with the assessment of what instigated the pain, how it can be terminated, and what management modalities are most effective for a particular patient. However, assessment is rarely that simple. Clinical manifestations of persistent pain are often complex and multifactorial in the older population. Even the perception of pain may differ from that perceived by those of less advanced years. Issues of physical accessibility to treatment, cost of drugs, the presence of coexisting illness, the use of concomitant medication, and the ability to understand the complaints of the patient who has cognitive impairment are only some of the factors that contribute to the complexity of the situation. Furthermore, the elderly patients condition is often complicated by depression, psychosocial concerns, denial, poor health, and poor memory. Without a thorough assessment, pain that is causing severe impairment may not be revealed for an array of personal, cultural, or psychological ...

The groups viral load averaged 2.3 log (200 copies), 59% had a blood plasma load above 50 copies, and 34% had a cerebrospinal fluid (CSF) load over 50. CD4 count averaged 420 and lowest-ever CD4 count 174. Fourteen of 1205 people (0.9%) with an undetectable load in blood plasma had detectable virus in CSF. But 122 of 300 CSF samples (41%) with a sub-50-copy load had detectable virus when the investigators used a more sensitive assay. And detectable CSF virus correlated with worse antiretroviral penetration of the central nervous system (CNS), as determined by CNS penetration-effectiveness scores (P = 0.03) [2]. And detectable sub-50-copy load was also associated with cognitive impairment. While 47% of the 1555 cohort members had normal neurocognitive performance scores, 21% had mild impairment, 30% moderate impairment, and 2% severe impairment. Comparing three studies that measured neurocognitive impairment--one in 1987 just before the antiretroviral era, one in 1995 just before HAART arrived, ...

Companies are good at accommodating physical disabilities, but what about cognitive disabilities? Now, that is a different story. In this edition of Attention Talk Radio, ADHD coach and host Jeff Copper interviews part-time ADHD coach Jay Carter, whose day job has included being the chair of a disability advisory committee for a Fortune 100 company. At present, he is on the corporate advisory board of U.S. Business Leadership Network which is an employer-led group who exists to help companies hire, train, and retain employees with disabilities. The interview will focus on the key things you need to attend to before addressing workplace accommodation, including disclosure, costs of accommodation, chain of influence, and why you need to understand your specific needs. If you have ADHD and struggle at work, this is the show for you ...

Sometimes kids take to reading like birds to the air. But other times difficulties in learning to read make it hard for them to spread their reading wings. In early childhood, those who are not ready developmentally to settle down and read often have what is called "strong motor drive" and want to be active instead. Lack of early literacy experiences, second language acquisition, vision impairment, cognitive disabilities such as incorrect perception of print and hearing difficulties may hold children back.

A loss of volume in the area of the brain known as the fornix was associated with cognitive decline in healthy older individuals, MRI studies found.
As we get older, most of us experience what psychologists refer to as age-related cognitive decline. Certain mental abilities, such as memory, processing speed, and visual perception begin to deteriorate steadily as early as the third decade of life, and then more rapidly from around 50 years of age, and this is associated with a gradual reduction of brain size [See: Big Data in Healthy Brain Aging and Cognitive Skills and the Aging Brain: What to Expect].. There are, however, significant differences between individuals. Although age-related cognitive decline is considered a normal part of the aging process, it happens quickly for some people, whereas others are far more resilient to it. Why do some peoples brains and thinking skills age better than others? Ian Deary of the University of Edinburgh addressed this question at the Royal Society in London this past week, in a lecture organized by the European Dana Alliance for the Brain (EDAB) and the University of the Third Age (U3A), an ...

Number Four: Understand your system. Understanding your system sounds complicated and derives from Demings "System of Profound Knowledge," but essentially this means there are four interacting components of the system that you need to consider: psychology, understanding the system, understanding the variation, and a theory of knowledge. First is the psychology of the people-why will people want to help you to change the incidence of postoperative cognitive dysfunction? Doctors in training may wish to participate in a project that they can present or write up; surgeons may be interested in the fact that improvements will make their patients and families happier and reduce length of stay; and anesthesiologists will wish to improve their patients experience and reduce the number of times they are called to the PACU to deal with a delirious patient. Second is understanding the system. How do the system components the patient will pass through interact? How can these interactions help and hinder ...

Canine cognitive dysfunction, or CCD, is caused by chemical and physical changes that affect the brain function of older dogs. Like people with Alzheimers, CCD usually comes on slowly and gradually gets worse.
I am sorry to hear about your daughters difficulty but glad to hear that she is making some progress towards recovery. Cognitive problems are very common in pediatric onset MS and require a management approach that differs from adults for two reasons; first, children like your daughter are at an age when the brain is potentially very adaptable and can recover from injury to an extent not possible in older adults. This makes it worthwhile to get expert assessment and individual learning plans and cognitive rehabilitation started as soon as possible. At the same time their brains are uniquely vulnerable to a variety of stressors and injuries; for this reason it is important to treat them aggressively and be attuned to the development of psychiatric issues (anxiety and depression) that may hinder their recovery. It is also important to solidify the final diagnosis as soon as possible ...

Objective: Computerized neurocognitive assessment tools (NCATS) are often used as a screening tool to identify cognitive deficits after mild traumatic brain injury (mTBI). However, differing methodology across studies renders it difficult to identify a consensus regarding the validity of NCATs. Thus, studies where multiple NCATs are administered in the same sample using the same methodology are warranted. Method: We investigated the validity of four NCATs: the ANAM4, CNS-VS, CogState, and ImPACT. Two NCATs were randomly assigned and a battery of traditional neuropsychological (NP) tests administered to healthy control active duty service members (n = 272) and to service members within 7 days of an mTBI (n = 231). Analyses included correlations between NCAT and the NP test scores to investigate convergent and discriminant validity, and regression analyses to identify the unique variance in NCAT and NP scores attributed to group status. Effect sizes (Cohens f2) were calculated to guide ...
Introduction/objective. It is widely accepted that researchers must have normative data that has been duly validated and culturally adapted in order to ensure that assessments of cognitive performance contain the lowest amount of contamination from other factors.1 This objective was clearly outlined for the Neuronorma Project, an extensive Spanish study that was published recently.2. Neuropsychological evaluation (NPE) for dementia may be more or less extensive and detailed depending on the complexity of the evaluation tools in use: brief scales, functional scales, simple test batteries, complex test batteries, and ideographic studies.3 The most recommendable method for performing NPE for dementia is to use a multidimensional test battery with psychometric properties including sensitive tests for each cognitive area.4 NPE is a key procedure in diagnosing, classifying, and monitoring the course of mild cognitive impairment, Alzheimers disease, and other types of dementia.5,6 The RBANS battery7 ...
Background: Recent studies demonstrated benefits of cognitive intervention in mild cognitive impairment (MCI), but few studies have determined long-term effects on cognition, conversion rate to Alzheimers disease, and the role of early intervention.. Method: A 6-month multicomponent cognitive group intervention was applied in participants with single- or multiple-domain amnestic MCI (defined according to Petersens criteria). One group (n = 12) received the intervention at the beginning of the study period and was compared with an active control group (n = 12) who received it after an 8-month time lag. Follow-up assessments were conducted at 15 and 28 months (study period was August 2007-December 2009). The primary outcome was change in cognitive function as determined by changes in scores on the Mini-Mental State Examination and the cognitive subscale of the Alzheimers Disease Assessment Scale (ADAS-cog), and the secondary outcomes were change in specific cognitive and noncognitive functions ...
