IntroductionWomen comprise two-thirds of people with dementia, making female sex a significant dementia risk factor. Both type 1 diabetes (T1D) and type 2 diabetes (T2D) are known dementia risk factors with an increasing global incidence. Understanding whether subtle sex differences persist in cognitive function prior to dementia in the context of diabetes may help elucidate the magnitude of sex effects on dementia risk.Research design and methodsWe examined cross-sectional data from the Study of Longevity in Diabetes (SOLID), a prospective cohort study of members of Kaiser Permanente Northern California aged 60 years and older with T1D (n=758), T2D (n=232) and without either T1D or T2D (n=247). We used factor analysis to generate summary scores of cognitive domains and used regression analyses to examine the associations between sex and cognition adjusting for sociodemographic and cardiovascular confounders.ResultsWe included 1237 participants (630 women and 607 men) with mean age 68 years. By design, the distribution of men and women in T1D, T2D and no diabetes was similar. Women had better cognitive performance than men in global cognition (β=0.21, 95% CI 0.16 to 0.26), language (β=0.08, 95% CI 0.004 to 0.15), executive function (β=0.13, 95% CI 0.05 to 0.20), episodic verbal memory (β=0.68, 95% CI 0.59 to 0.77) and attention (β=0.20, 95% CI 0.11 to 0.28) but not in episodic visual memory (β=0.006, 95% CI −0.07 to 0.09) adjusting for age and education independent of diabetes status. We did not find an interaction between sex and diabetes status for any of the cognitive outcomes.ConclusionsWomen in late mid-life have better cognitive performance than men in many cognitive domains independent of the presence of T1D or T2D. Further work is required to understand whether these differences change over time or in older cohorts and to understand their relationship to subsequent dementia.

Abstract Purpose The purpose of this study was to explore if symptom factors are related to cognitive outcomes. Prior studies have examined the relationship of individual symptoms to cognition. However, the relation between empirically-derived symptom factors and cognitive outcomes has yet to be explored. Methods Data were extracted via retrospective chart review of 691 patients (aged 10–24, mean: 14.99±2.63). Participants completed ImPACT and the PCSS within 14 days of injury (mean: 9.27±3.37). Predictors were PCSS factor scores of Cognitive-Fatigue-Migraine (CFM), Affective (AFF), Somatic (SOM), and Sleep (SLP) (Kontos et al., 2012). Outcomes examined were ImPACT composite scores. Univariate analyses were performed and values with p < 0.10 were entered into stepwise linear regression (LR) models. Retained predictors in each LR model had p values <.05. Results Verbal memory was predicted by CFM, SOM, age, and gender. Visual memory was predicted by CFM and SOM. Visual motor speed was predicted by age, gender, CFM, SOM, and AFF. Reaction time was best predicted by SOM, CFM, and age. The variance explained was fairly small (0.08 to 0.21). SLP was not a significant predictor in any LR. Conclusion CFM and SOM factors were most predictive of lower cognitive performance, similar to prior studies linking dizziness to longer recovery and post-traumatic migraine to worse cognitive performance. These findings underscore the clinical importance of diverse symptom assessment and injury education. Higher CFM and SOM scores may also serve as proxy for injury severity, which we would expect to be associated with worse cognitive performance.

Magnetic resonance (MR) images and neuropsychological testing data of 69 carbon monoxide (CO) poisoned patients were prospectively obtained within 1 day of CO poisoning, two weeks and six months. CO patients' Day 1 cross-sectional fornix surface area measurements, corrected for head size by using a fornix-to-brain ratio (FBR), were compared to normal age and gender-matched controls. Additionally, a within-subjects analysis was performed comparing the mean areas between CO patients' Day 1, 2 weeks and 6-month FBR. The FBR was correlated with patients' neuropsychological data. There were no significant differences between CO patients' Day 1 fornix measurements compared to normal control subjects. However, significant atrophic changes in the fornix of CO poisoned patients occurred at two weeks with no progressive atrophy at 6 months. By 6 months, CO patients showed significant decline on tests of verbal memory (when practice effects were taken into account), whereas visual memory, processing speed and attention/concentration did not decline. This study indicates that CO results in brain damage and cognitive impairments in the absence of lesions and other neuroanatomic markers. (JINS, 2001, 7, 640–646.)

Many lifestyle factors have been linked to cognitive function but little is known about their combined effect. An overall lifestyle pattern for people living in the Mediterranean basin has been proposed, including diet, but also physical activity, sleep and daily living activities with social/intellectual aspects. We aimed to examine the associations between a combination of these lifestyle factors and detailed cognitive performance. A total of 1716 participants from the Hellenic Longitudinal Investigation of Ageing and Diet (HELIAD), a population-based study of participants ≥65 years, were included in this analysis. Lifestyle factors were evaluated using standard, validated questionnaires and a Total Lifestyle Index (TLI) was constructed. Cognitive outcomes included mild cognitive impairment (MCI) diagnosis, a composite z-score (either continuous or with a threshold at the 25th percentile) and z-scores for five cognitive domains. A higher TLI was associated with 65% reduced odds for MCI in the non-demented individuals and 43% reduced odds for low global cognition when MCI participants were excluded, a risk reduction equivalent to 9 and 2.7 fewer years of ageing, respectively. Each lifestyle factor was differentially associated with domain-specific cognitive performance. Our results suggest that a TLI, more so than single lifestyle parameters, may be related to cognitive performance.

AbstractINTRODUCTIONFew population studies have investigated whether longitudinal decline after delirium in mid-to-late life might affect specific cognitive domains.METHODSParticipants from a birth cohort completing assessments of search speed, verbal memory and the Addenbrooke’s Cognitive Examination at age 69 were asked about delirium symptoms between ages 60-69. Linear regression models estimated associations between delirium symptoms and cognitive outcomes.RESULTSPeriod prevalence of delirium between 60 and 69 was 4% (95% CI 3.2%,4.9%). Self-reported symptoms of delirium over the seventh decade were associated with worse scores in the Addenbrooke’s Cognitive Examination (−1.7 points, 95% CI −3.2, −0.1, p=0.04). In association with delirium symptoms, verbal memory scores were initially lower, with subsequent decline in search speed by age 69. These effects were independent of other Alzheimer’s risk factors.DISCUSSIONDelirium symptoms may be common even at relatively younger ages, and their presence may herald cognitive decline, particularly in search speed, over this time period.

• Background Some studies have indicated a decline in patients’ cognitive performance after coronary artery bypass graft surgery. • Objective To evaluate cognitive performance before and after coronary artery bypass graft surgery. • Methods Patients’ cognitive performance before and after coronary artery bypass graft surgery was evaluated in a prospective observational multicenter study in 5 academic medical centers. A total of 242 men and 123 women were evaluated before surgery; 333 men and 216 women, 5 to 11 months after surgery (197 men and 99 women were evaluated both before and after surgery). Verbal ability, attention/concentration, logical/verbal and visual memory, and facial recognition were measured. Data on demographic, medical, and psychosocial characteristics also were collected. • ResultsAfter surgery, patients’ overall performance improved (P &lt; .001) for attention/concentration, verbal fluency, and logical/verbal memory. Patients with more education (high school or greater) performed better on each test (P &lt; .001) than did patients with less education. No strong effects of sex or age on cognitive performance were observed before or after surgery, and no important differences in sex, age, or education were associated with changes in scores from before to after surgery. • Conclusion On average, cognitive performance improved rather than declined after coronary artery bypass graft surgery. The improvements were consistent across sex, age, and education.

ObjectiveGiven the limited information on cognitive function before Parkinson disease (PD) clinical onset in the general population, we sought to assess prodromal PD (pPD) probability and relate it to detailed cognitive performance in a community cohort.MethodsIn a population-based cohort of 1,629 dementia-free and PD-free participants ≥65 years of age in Greece, we assessed probability of pPD according to the International Parkinson and Movement Disorder Society's criteria. Clinical cognitive diagnoses (cognitively unimpaired, mild cognitive impairment [MCI], dementia) considering neuropsychological testing and functional status were assigned in consensus conferences. Cognitive performance in 5 cognitive domains was assessed by a detailed neuropsychological battery and summarized in the form of z scores. We investigated associations between pPD probability (and its individual constituents) and cognitive outcomes.ResultsThe median probability of pPD was 1.81% (0.2%–96.7%). Participants with MCI had higher probability of pPD compared to those with normal cognition (p < 0.001). Higher probability of pPD was related to lower performance in all cognitive domains (memory, language, executive, attention, and visuospatial function) (p < 0.001). Lower cognitive performance was further associated with certain nonmotor markers of pPD, such as daytime somnolence, depression, urinary dysfunction, constipation, and subthreshold parkinsonism (p < 0.001).ConclusionsHigher probability of pPD was associated with lower cognitive performance in all domains and higher probability of MCI. This may reflect a widespread pathologic process although future studies are warranted to infer causality. These results suggest to clinicians that they should assess cognition early, and to researchers that they should further look into the possible mechanisms that may underlie this observation.

Introduction. Very few studies have examined the neuropsychological performance of HIV-positive women, and even fewer have attempted a comparison of cognitive functioning by gender. The aim of this study was to describe the nature of the neuropsychological performance of HIV seropositive patients by gender.Methods. A clinical sample made up of 151 subjects was recruited to participate in this study. All of the subjects underwent the same assessment process, consisting of a neuropsychological evaluation and an interview to gather sociodemographic, toxicological, and clinical data.Results and Discussion. Despite the fact that men obtained higher scores in visual memory, attention/psychomotor speed, and abstract reasoning/verbal intelligence, these differences were not statistically significant. In contrast, significant differences were found depending on subjects’ serological status. Seropositive participants’ neuropsychological performance was significantly lower than that of the seronegative participants in all of the areas assessed as follows: (1) visual memory; (2) attention/psychomotor speed; (3) abstract reasoning/verbal intelligence; (4) verbal memory for texts; (5) verbal memory for digits and words.Conclusions. The results from this study reveal no significant gender differences in the cognitive performance of patients infected with HIV-1.

Purpose To evaluate the effects of androgen-deprivation therapy (ADT) on cognitive function in men with nonmetastatic prostate cancer (PC). Patients and Methods The following three groups of men age 50 years or older and matched on age and education were enrolled: patients with PC starting continuous ADT (n = 77), patients with PC not receiving ADT (PC controls, n = 82), and healthy controls (n = 82). A battery of 14 neuropsychological tests, examining eight cognitive domains, was administered at baseline, 6 months, and 12 months. Changes in cognitive scores over time were analyzed using the following three approaches: multivariable linear regression; the proportion of participants per group with 1 standard deviation (SD) or greater declines, and the proportion of participants who declined by at least 1.5 SD on two or more tests. Results The mean age and education level of participants were 68.9 years (range, 50 to 87 years) and 15.4 years of education (range, 8 to 24 years), respectively. Adjusted for age and education, all three cohorts had similar cognitive scores at baseline other than in one test of working memory. In adjusted regressions, ADT use was not associated with significant changes in the domains of attention/processing speed, verbal fluency, verbal memory, visual memory, or cognitive flexibility at either 6 months (all P > .05) or 12 months (all P > .05). One test each of immediate memory (P = .029), working memory (P = .031), and visuospatial ability (P = .034) were worse among ADT users than controls at 12 months, but these findings were not confirmed using other analytic approaches. Conclusion There is no consistent evidence that 12 months of ADT use has an adverse effect on cognitive function in elderly men with PC.

Background: The estimation of premorbid intelligence (PI) is needed for an accurate diagnosis. Objective: This study aimed to estimate the cognitive performance taking into account the PI in Parkinson’s disease (PD) compared to healthy controls (HC); and to analyze the discrepancies between the current and the predicted cognitive performance based on the PI. Method: Semantic fluency, verbal and visual memory, and executive functions were assessed in 39 PD and 162 HC. A linear regression model was used to analyze the discrepancies between the predicted cognitive performance and the current raw scores through PI variables (Word Accentuation Test (WAT), Pseudo-Words (PW) Reading subtest from PROLEC-R, age, and years of education). ROC analyses were performed to assess their diagnostic properties. Results: Significant differences were found in the raw cognitive scores between patients and HC [semantic fluency (t = 6.07; p < 0.001), verbal memory (t = 6.63; p < 0.001), and executive functions (t = 2.57; p = 0.013), and in visual memory (t = 1.97; p = 0.055 marginally significant)]. Compared to HC, PD patients presented higher discrepancies between the predicted cognitive performance and the raw scores in semantic fluency, verbal memory, visual memory, executive functions (AUC = 0.78, 0.78; 0.64, 0.61, respectively). Conclusion: The magnitude of the discrepancies scores between the current and the predicted cognitive performance based on PI indicates the presence of cognitive decline in the specific cognitive domain in PD patients. This study underlines the usefulness of premorbid measures and variables, such as WAT, PW, age, and years of education, to more accurately estimate the cognitive performance in PD.

Objective: To study the status of visual and verbal memory status among children with epilepsy and effects on schooling. Methods:This descriptive cross-sectional study enrolled children aged 5 to 15 years who have been diagnosed to have epilepsy and has been seizure free during last one month. Enrolled children (81) were evaluated by using two sub tests selected from the National Institute of Mental Health and Neuro Sciences(NIMHANS) Neuropsychological Battery for Children, Rey’s Auditory Verbal Learning test and Memory for Designs test, for verbal and visual memory status respectively and the child was graded on the basis of the standard scores. Schooling details were obtained by questioners to care taker. Results: Memory impairment (MI) was identied in 50 (61.7%) Children with Epilepsy (CWE) (predominantly verbal memory impairment). 20 (25%) CWE were not attending age appropriate class. Among these 20 CWE, 17(85%) children had memory impairment. p: 0.01. There were 25 CWE performing poorly, among them 22(88%) children had memory impairment. p <0.0024. A total of 8 children were school dropouts and all 8 had MI (100%).Conclusions:MI was found to be very common in CWE. MI among CWE was found to negatively inuence age appropriate schooling and school performance. Early screening and appropriate support may improve the outcome.
