INTRODUCTION: Inflammation of the central nervous system is increasingly regarded as having a role in cognitive disorders such as dementia and depression, but it is not clear how such inflammation relates to other aspects of neuropathology, structural and functional changes in the brain and symptoms (as assessed via clinical and neuropsychological assessment and MRI). This study will explore these pathophysiological mechanisms using positron emission tomography (PET) which allows in vivo imaging of inflammation, amyloid and τ deposition, together with neuropsychological profiling, MRI and peripheral biomarker analysis...

Older people are particularly exposed to stressful events, known to activate the hypothalamus-pituitary-adrenal axis resulting in increased cortisol levels. High cortisol has been associated with deleterious effects on cognition. We hypothesized that stressful life events could increase cortisol secretion leading to cognitive impairment. A cross-sectional analysis was conducted using data from Colaus/PsyColaus, a longitudinal population-based study among Lausanne residents. Salivary cortisol samples were obtained from 796 nondemented subjects aged at least 65...

PURPOSE OF REVIEW: Alzheimer's disease is most likely universal in older individuals with Down syndrome, due to having three copies of the amyloid precursor protein gene, resulting in amyloid-beta plaque deposition. Down syndrome is an important population in which to consider clinical trials of treatments to prevent or delay the development of dementia. However, assessment of subtler cognitive changes is challenging due to the presence of intellectual disability. RECENT FINDINGS: Recent research confirmed that older adults with Down syndrome often present with cognitive decline: more than 80% may experience dementia by age 65 years...

BACKGROUND/AIMS: Differences in cognition between frontotemporal dementia (FTD) and Alzheimer disease (AD) are well described in clinical cohorts, but have rarely been confirmed in studies with pathologic verification. For emerging therapeutics to succeed, determining underlying pathology early in the disease course is increasingly important. Neuropsychological evaluation is an important component of the diagnostic workup for AD and FTD. Patients with FTD are thought to have greater deficits in language and executive function while patients with AD are more likely to have deficits in memory...

Dementia is characterized by the impairment of cognition and behavior of people over 65 years. Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder in the world, as approximately 47 million people are affected by this disease and the tendency is that this number will increased 62% by 2030. Two microscopic features assist in the characterization of the disease, the amyloid plaques and neurofibrillary agglomerates. All these factors are responsible for the slow and gradual deterioration of memory that affect language, personality or cognitive control...

BACKGROUND: Studies of amnestic mild cognitive impairment (aMCI) and late-life depression (LLD) have examined the similarities and differences between these syndromes, but few have investigated how the cognitive profile of comorbid aMCI and subclinical depressive symptoms (aMCI/D+) may compare to that of aMCI or LLD. Memory biases for certain types of emotional information may distinguish these groups. METHODS: A total of 35 aMCI, 23 aMCI/D+, 13 LLD, and 17 elderly controls (CONT) rated the valence (positive, negative, or neutral) of 30 pictures from the International Affective Picture System...

BACKGROUND: The quality of life (QoL) of informal caregivers of people with Parkinson's disease (PD) (PwP) can be affected by the caring role. Because of cognitive symptoms and diminished activities of daily living, in addition to the management of motor symptoms, carers of PwP and cognitive impairment may experience increased levels of burden and poorer QoL compared with carers of PwP without cognitive impairment. This study aimed to investigate the impact of cognitive impairment in PD upon QoL of carers...

OBJECTIVE: Hyperfamiliarity is a phenomenon where new stimuli are perceived as familiar. Previous studies have demonstrated familiarity disorder in mild cognitive impairment (MCI), but mostly from the perspective of a neuropsychological approach, and the exact correlation of MCI aetiologies with the phenomenon remains uncertain. Based on current evidence suggesting a frontal-subcortical pathway contributing to familiarity processing, we hypothesize that individuals with a vascular aetiology of MCI will likely suffer more familiarity deficits...

OBJECTIVE: This pilot study investigated the effects of multiple training modalities on cognition, neuropsychiatric symptoms, caregivers' burden, and quality of life in patients with Alzheimer's disease (AD). PATIENTS AND METHODS: This intervention study was conducted in 24 patients with AD aged ≥65 years with a Clinical Dementia Rating (CDR) score of 0.5-1. The patients were assigned to receive multiple training modalities (1 hour for each training: Tai Chi, calligraphy, and drawing) over a 6-week period in either the experimental group (n=14) or the comparison group (n=10)...

Frontotemporal dementia is a neurodegenerative disorder of which the behavioral variant is most common. This condition is currently considered the most common cause of dementia in people younger than 60 years. Here, we present two unrelated cases in which the typical symptoms were cognitive and behavioral progressive deterioration and psychiatric disorders such as disinhibition, impulsive acts, apathy, lack of empathy, stereotypies, and changes in eating habits. The first case exhibited pathological gambling as the initial symptom and resided in a psychiatric facility for a year...

The authors studied the effects of rasagiline on cognition in a sample of 50 nondemented patients with mild to moderate Parkinson's disease (PD) using a double-blind, placebo controlled design. Cognition and motor symptoms were assessed at baseline and after 6 months of receiving either rasagiline or placebo. Participants receiving rasagiline showed improvement in their motor symptoms of PD compared to participants receiving placebo. No significant changes in performance on neuropsychological measures of cognition were observed between the groups...

INTRODUCTION: An important area in neuropsychological assessment is that of psychological and behavioural symptoms. The Cambridge Behavioural Inventory (CBI) is a self-report measure aimed at relatives which takes account of a wide range of behavioural symptoms that may occur during the course of neurological diseases. The main objective of the study is to test the clinical usefulness of its Spanish adaptation. SUBJECTS AND METHODS: The CBI was completed by 215 members of kin of patients referred from neurology and psychiatry services...

BACKGROUND: In Parkinson's disease (PD), cognitive impairment is an important non-motor symptom heralding the development of dementia. Effective treatments to slow down the rate of cognitive decline in PD patients with mild cognitive impairment are lacking. Here, we describe the design of the Parkin'Play study, which assesses the effects of a cognitive health game intervention on cognition in PD. METHODS/DESIGN: This study is a multicentre, phase-II, open-randomized clinical trial that aims to recruit 222 PD patients with mild cognitive impairment...

PURPOSE: To examine an association between the overactive bladder symptom score (OABSS) and neuropsychological parameters. Moreover, we investigate the factors that affect each item in the questionnaire. MATERIALS AND METHODS: A total of 376 patients (males: 184; females: 192) with probable Alzheimer's disease (AD) were recruited. Cognitive testing was conducted using the Mini Mental Status Examination (MMSE), Clinical Dementia Rating (CDR) scale, Global Deterioration Scale (GDS), and Barthel Activities of Daily Living (ADL)...

Objective: Executive cognitive functioning is essential in private and working life and is sensitive to stress and aging. Cardiovascular (CV) health factors are related to cognitive decline and dementia, but there is relatively few studies of the role of CV autonomic regulation, a key component in stress responses and risk factor for cardiovascular disease (CVD), and executive processes. An emerging pattern of results from previous studies suggest that different executive processes may be differentially associated with CV autonomic regulation...

Disinhibition is an important symptom in neurodegenerative diseases. However, the clinico-anatomical underpinnings remain controversial. We explored the anatomical correlates of disinhibition in neurodegenerative disease using the perspective of grey and white matter imaging. Disinhibition was assessed with a neuropsychological test and a caregiver information-based clinical rating scale in 21 patients with prefrontal syndromes due to behavioural variant frontotemporal dementia (n = 12) or progressive supranuclear palsy (n = 9), and healthy controls (n = 25)...

OBJECTIVES: The distinction between dementia and mild cognitive impairment (MCI) relies upon the evaluation of independence in instrumental activities of daily living (IADL). Self- and informant reports are prone to bias. Clinician-based performance tests are limited by long administration times, restricted access, or inadequate validation. To close this gap, we developed and validated a performance-based measure of IADL, the Sydney Test of Activities of Daily Living in Memory Disorders (STAM)...

BACKGROUND The primary manifestation of Alzheimer's disease (AD) is decline in memory. Dysexecutive symptoms have tremendous impact on functional activities and quality of life. Data regarding frontal-executive dysfunction in mild AD are controversial. The aim of this study was to assess the presence and specific features of executive dysfunction in mild AD based on Cambridge Neuropsychological Test Automated Battery (CANTAB) results. MATERIAL AND METHODS Fifty newly diagnosed, treatment-naïve, mild, late-onset AD patients (MMSE ≥20, AD group) and 25 control subjects (CG group) were recruited in this prospective, cross-sectional study...

Background: Adult height, weight, and adiposity measures have been suggested by some studies to be predictors of depression, cognitive impairment, and dementia. However, the presence of confounding factors and the lack of a thorough neuropsychological evaluation in many of these studies have precluded a definitive conclusion about the influence of anthropometric measures in cognition and depression. In this study we aimed to assess the value of height, weight, and abdominal perimeter to predict cognitive impairment and depressive symptoms in aged individuals...

Late-life depression is frequently associated with cognitive impairment. Depressive symptoms are often associated with or even precede a dementia syndrome. Moreover, depressive disorders increase the risk of persistence for mild cognitive impairment and dementia. Here, we present both the current state of evidence and future perspectives regarding the integration and value of clinical assessments, neuropsychological, neurochemical, and neuroimaging biomarkers for the etiological classification of the dementia versus the depression syndrome and for the prognosis of depression relating to dementia risk...
