BACKGROUND: Slow participant recruitment impedes Alzheimer disease research progress. Although research suggests that direct involvement with potential participants supports enrollment, strategies for how best to engage potential participants are still unclear. PURPOSE: This study explores whether community health fair (HF) attendees who engage in a brief cognitive screen (BCS) are more likely to enroll in research than attendees who do not complete a BCS. SUBJECTS: A total of 483 HF attendees...

Memantine extended release (ER) significantly outperformed placebo on co-primary endpoints of Clinician's Interview-based Impression of Change Plus Caregiver Input (CIBIC-Plus) and baseline to endpoint changes on the Severe Impairment Battery (SIB) in a 24-week, randomized trial (NCT00322153) in patients with moderate to severe Alzheimer's disease taking a cholinesterase inhibitor (ChEI). A post hoc analysis compared patients receiving memantine ER/ChEI to placebo/ChEI for time to onset of response and if the response was maintained (achieving improvement at weeks 8, 12, or 18 and maintaining through endpoint/week 24) on the SIB, the Neuropsychiatric Inventory (NPI), CIBIC-Plus, and Activities of Daily Living (ADL) using Fisher exact test...

INTRODUCTION: According to latest research, a percentage of cognitively impaired drivers fail to recognize their areas of weakness and overestimate their driving abilities. METHODS: Twenty-seven individuals with amnestic mild cognitive impairment (MCI) and 26 healthy elderly drivers participated in a driving simulator study. After the driving assessment, participants were asked to self-evaluate their performance in comparison with what they considered as average for people of similar age and educational level...

PURPOSE: Older adults experience impaired driving performance, and modify their driving habits, including limiting amount and spatial extent of travel. Alzheimer disease (AD)-related pathology, as well as spatial navigation difficulties, may influence driving performance and driving behaviors in clinically normal older adults. We examined whether AD biomarkers [cerebrospinal fluid (CSF) concentrations of Aβ42, tau, and ptau181] were associated with lower self-reported spatial navigation abilities, and whether navigation abilities mediated the relationship of AD biomarkers with driving performance and extent...

The purpose of this review is to provide an overview of the research regarding circadian rhythms in Alzheimer disease (AD). Furthermore, this paper explores the role of melatonin in the pathogenesis of AD and the limitation of trials addressing circadian rhythms disturbances in the AD population. A literature search using Medline with PubMed and Embase was carried out identifying papers focusing on circadian rhythms in AD. Sleep disorders and especially circadian rhythm disturbances are very common in the elderly population but definitely more pronounced in patients with AD...

The diagnostic accuracy of hexamethylpropyleneamine oxime (HMPAo) single-photon emission computed tomography (SPECT) in Alzheimer disease (AD) remains undetermined in a "real-life" clinical population. The objective was to determine the HMPAo SPECT hypoperfusion pattern in cognitively impaired patients with positive CSF AD biomarker and to evaluate its diagnostic accuracy. This study included 120 patients referred to a university memory clinic assessed using HMPAo SPECT, MRI, and CSF biomarkers. Three biomarker signatures suggestive of AD were analyzed (1, Aß1-42; 2, Aß1-42+t-tau and/or p-tau; 3, Aß1-42/p-tau)...

OBJECTIVE: Retinopathy impacts over one-third of those with diabetes mellitus and is associated with impaired cognitive performance and cerebrovascular lesions in middle-aged adults with type 1 diabetes. However, the association between diabetic retinopathy (DR) and risk of dementia in type 1 diabetes is unknown. We investigated the association between DR and incident dementia in a large, elderly population with type 1 diabetes. METHODS: A cohort of 3742 patients with type 1 diabetes aged 50 years and above was followed from January 1, 1996 to September 30, 2015 for incident dementia...

Computerized cognitive assessment tools may facilitate early identification of dementia in the primary care setting. We investigated primary care physicians' (PCPs') views on advantages and disadvantages of computerized testing based on their experience with the Computer Assessment of Mild Cognitive Impairment (CAMCI). Over a 2-month period, 259 patients, 65 years and older, from the family practice of 13 PCPs completed the CAMCI. Twelve PCPs participated in an individual interview. Generally, PCPs felt that the relationship between them and their patients helped facilitate cognitive testing; however, they thought available paper tests were time consuming and not sufficiently informative...

BACKGROUND: Social cognition is not routinely assessed in older adults. We report population-based normative data on the Social Norms Questionnaire (SNQ22) which asks individuals about the appropriateness of specific behaviors in hypothetical scenarios, errors being related either to breaking with norms or to over-adhering to perceived norms. Total SNQ scores represent the number of correct responses while subscale scores are error totals. METHODS: We administered the SNQ22 to 744 adults aged 65+ within a population-based study, and examined the distribution of scores by demographics, other cognitive measures, and Clinical Dementia Rating (CDR)...
