AIM: The number of people with dementia is rapidly increasing as populations around the world age. It is important to grasp the characteristic features of mild cognitive impairment (MCI) for early detection and prevention of dementia. METHODS: We examined 408 individuals recruited from a health checkup for metabolic syndrome, which comprised three groups: normal (n = 325), MCI (n = 55) and apparent cognitive decline (ACD; n = 28). We compared cognitive/affective functions and exercise/hobby habits with assessments of vascular risk factors and results from computerized touch-panel tests...

BACKGROUND: The prevalence of obesity, as well as evidence about this pathology as a risk factor for cognitive decline and dementia in the elderly, is increasing worldwide. Executive functions have been found to be compromised in most studies, although the specific results are dissimilar. Obese young women constitute an interesting study and intervention group, having been found to be unaffected by age and hormonal negative effects on cognition and considering that their health problems affect not only themselves but their families and offspring...

BACKGROUND: Mild cognitive impairment (MCI) and dementia are reaching epidemic proportions in Asia. Lack of awareness and late presentation are major obstacles to early diagnosis and timely intervention. Cognitive screening may be an effective method for early detection of dementia in Asia. The purpose of this work was to study the characteristics of subjects volunteering for cognitive screening in an Asian setting and to determine the prevalence of MCI. METHODS: Retrospective and cross-sectional data from community subjects attending a screening program from 2008 to 2013 were analyzed...

OBJECTIVE: Prior literature has identified inconsistent longitudinal associations between total cholesterol and cognitive decline. The authors examined prospective nonlinear relations of coincident trajectories of total cholesterol and cognitive function among persons free of stroke, dementia, and other neurological disease. METHOD: Up to 1,601 participants from the Baltimore Longitudinal Study of Aging (aged 19-93, 51% male, 75% White) underwent fasting cholesterol measurement and neuropsychological assessment on up to 12 occasions (M = 3...

An increased frequency of apolipoprotein E4 has been reported in both late-onset Alzheimer's disease and multi-infarct dementia. It has also been suggested that the Apo E4 allele may increase plasma cholesterol. Late-onset depression (LOD) is frequently associated with cerebrovascular changes as well as cognitive impairment. In this study, Apo E4 phenotyping was performed using isoelectric focussing in 23 patients with LOD and 8 with early onset depression. None had SDAT at time of evaluation. Nine LOD patients and none of EOD patients had E4/3 alleles (p<0...

BACKGROUND: Dementia will inevitably increase in the aging world. Moreover there is no cure for dementia. Therefore, primary prevention is very important. There are several factors possibly and/or certainly influencing dementia risk including non-modifiable and modifiable risk factors. There are evidences that the risk of developing dementia may be reduced by modifiable risk factors. LIFESTYLE FACTORS: The strategies are to encourage regular physical and mental exercise in midlife and in late-life...

EDITORIAL
Gwenn S Smith
Neuroplasticity can be defined as a final common pathway of neurobiological processes, including structural, functional or molecular mechanisms, that result in stability or compensation for age- or disease-related changes. The papers in this issue address the aging process, as well as depression, dementia, and stroke and a range of interventions, including manipulations in behavior (physical and cognitive activity/exercise), physiological factors (caloric restriction, cholesterol), pharmacologic treatments (AMPA receptors) and manipulation of brain magnetic fields and electrical activity (transcranial magnetic stimulation, magnetic seizure therapy, and deep brain stimulation)...

BACKGROUND: As the older population increases so does the number of older psychiatric patients. Elderly psychiatric patients manifest certain specific and unique characteristics. Different subtypes of depressive syndromes exist in late-life depression, and many of these are associated with cognitive impairment. MATERIALS AND METHODS: A total of 109 depressive patients and 30 normal subjects matched by age and educational level were evaluated using a neuropsychiatric interview and an extensive neuropsychological battery...

OBJECTIVE: Associations of thyroid dysfunction with cognitive impairment and depression in late-life have been described but remain controversial. This study aimed to investigate the associations of serum thyroid stimulating hormone (TSH) levels with cognitive impairment and depression after controlling for potential confounding factors. METHODS: The sample consisted of 495 community residents aged 65 or over in whom serum TSH had been assayed. Cognitive impairment was defined using the Community Screening Interview for Dementia, and depression was diagnosed using the Geriatric Mental State schedule...

In a 2009 Cochrane review, the authors concluded that there is good evidence that statins, given in late life to people at risk of vascular disease, have no effect in preventing Alzheimer's disease or dementia. A related issue, which remains unclear, is whether statins improve cognitive function. While some studies have shown a beneficial effect of statins on cognitive function, others have observed mild detrimental effects on cognition. Our aim was to assess cognitive function in community-dwelling elderly participants treated with statins compared with their untreated counterparts (i...

OBJECTIVE: To contrast early-onset (<60 years) and late-onset (>60 years) depression in geriatric patients by evaluating differences in cognition, vascular comorbidity and sociological risk factors. Both patient groups were compared with normal subjects. MATERIALS AND METHODS: We recruited 76 patients with depressive symptoms (37 late onset and 39 early onset) and 17 normal controls matched by age and educational level. All subjects were assessed using a semistructured neuropsychiatric interview and an extensive neuropsychological battery...

BACKGROUND AND PURPOSE: Though clinical cardiovascular and cerebrovascular diseases are established risk factors for cognitive decline and dementia, less is known about the relations between vascular health and cognition among individuals without these diseases. Carotid intimal medial thickness (IMT), a measure of subclinical vascular disease, is associated with concurrent decrements in cognitive function, but relatively little research has examined longitudinal relations between carotid IMT and prospective cognitive decline...

Alzheimer's disease is a progressive and fatal neurodegenerative disorder in which the novel drugs can slow down the progression in the early phase. Our purpose was to find biological markers, which would detect neuropathology in the prodromal and early phase of Alzheimer's disease. Beside the routine diagnostic methods, neuropsychological test, auditory event related potential and special laboratory tests were performed among subjects with Alzheimer's disease, vascular dementia, mild cognitive impairment and major depression compared to a healthy control group...

BACKGROUND: Although several studies have investigated the association between cholesterol and dementia, few have examined cholesterol and decline across cognitive domains. We examined serum total and high-density lipoprotein (HDL) cholesterol, total-to-HDL ratio, and trajectories across cognitive domains. METHODS: Participants were 436 community-residing women (70-79 years old) in the Women's Health and Aging Study II; they were screened to be physically high-functioning and cognitively intact at baseline...

BACKGROUND: N-3 fatty acids (FA) have an important role in brain development and function. However, there is conflicting evidence concerning the relationship between n-3 FA and dementia in older persons. METHODS: In the Invecchiare in Chianti (InCHIANTI) study, we measured plasma FA by gas chromatography in 935 community-dwelling older persons randomly extracted from the population of two towns near Florence, Italy. Cognitive impairment was measured using the Mini-Mental Status Examination...

Adrenal function and aging have been the object of intense interest recently, especially as regards dehydroepiandrosterone sulfate (DHEA-S), which is of major importance, since it is distinct from cortisol and aldosterone in declining with age. In a group of healthy old Tunisians, we investigated the association between cortisol and DHEA-S, on the one hand, and age, sex, lifestyle, physical health, including the body mass index (BMI), physical activity, and smoking indicators, on the other hand. We observed that cortisol concentrations did not change with aging, while DHEA-S concentrations decrease with age in both sexes...

The most efficient strategy for combating Alzheimer's disease (AD) is to prevent the onset of clinically significant symptoms. Determining the clinical characteristics, risk factors, and indices of cognitive reserve would help in achieving this goal. The aim of this study was to determine the risk factors for AD and vascular dementia (VD) in the elderly and to highlight the importance of risk factor modification in the early diagnosis. Consecutive 1436 patients (mean age=72.7+/-6.9 years, 34.2% male) were enrolled in the study...

CONTEXT: Recent evidence suggests that treatment of mild-to-moderate Alzheimer's disease (AD) with atorvastatin provides significant benefit on the Alzheimer Disease Assessment Scale-Cognitive (ADAS-cog) after 6 months. OBJECTIVE: To determine if benefit on ADAS-cog performance produced by atorvastatin is influenced by severity of cognitive impairment, circulating cholesterol levels, or apolipoprotein E genotype. DESIGN: A double-blind, placebo-controlled, randomized (1:1) trial with a 1-year exposure to atorvastatin calcium or placebo...
