Objective: To examine whether engagement in physical activity might favorably alter the agedependent evolution of Alzheimer disease (AD)-related brain and cognitive changes in a cohort of at-risk, late-middle-aged adults. Methods: Three hundred seventeen enrollees in the Wisconsin Registry for Alzheimer’s Prevention underwent T1 MRI; a subset also underwent ¹¹C-Pittsburgh compound B–PET (n = 186) and […]
A comparison of neurocognitive impairment in younger and older adults with major depression
Thomas, A. J.,

Porter, R. J.,

Ferrier, I. N.,
O'Brien, J. T.
Background: Neurocognitive impairment is a well-recognized feature of depression that has been reported in younger and older adults. Similar deficits occur with ageing and it is unclear whether the greater deficits in late-life depression are an ageing-related phenomenon or due to a difference in the nature of late-life depression itself. We hypothesized that ageing alone […]
Differential perceptions of quality of life (QoL) in community-dwelling persons with mild-to-moderate dementia
Tay, Laura,
Chua, Kia Chong,
Chan, Mark,
Lim, Wee Shiong,
Ang, Yue Ying,
Koh, Evonne,
Chong, Mei Sian
Background: Discordance between patient- and caregiver-reported quality of life (QoL) is well recognized. This study sought to (i) identify predictors of discrepancy between patient- and caregiver-rated QoL amongst community-dwelling persons with mild-to-moderate dementia, and (ii) differentiate between patients who systematically rate their QoL lower versus those who rate their QoL higher relative to their caregiver […]
Impaired glucose metabolism slows executive function independent of cerebral ischemic lesions in Japanese elderly: the Takahata study

Wada, Manabu,
Momma, Tadasuke,
Ueki, Masao,
Kawanami, Toru,
Daimon, Makoto,
Suzuki, Kyoko,
Tamiya, Gen,
Kato, Takeo
Objective: Age is known to influence the risk of both cerebral ischemic lesions and impaired cognitive function. Diabetes mellitus (DM) can also be associated with cognitive impairment. However, there has been no study of neuropsychological performance in association with glucose metabolism status and cerebral ischemic lesions in same-aged, community-dwelling elderly persons. The present study was […]
The Montreal Cognitive Assessment (MoCA) in geriatric rehabilitation: psychometric properties and association with rehabilitation outcomes
Sweet, Lisa,
Van Adel, Mike,
Metcalf, Valerie,
Wright, Lisa,
Harley, Anne,
Leiva, René,
Taler, Vanessa
Background: Cognitive status has been reported to be an important predictor of rehabilitation outcome. The Montreal Cognitive Assessment (MoCA) was designed to overcome some of the limitations of established cognitive screening tools such as the Mini-Mental State Examination (MMSE). The purpose of this study is to evaluate the psychometric characteristics of the MoCA as a […]
Association of depression with accelerated cognitive decline among patients with type 2 diabetes in the ACCORD-MIND trial

Importance: Depression has been identified as a risk factor for dementia among patients with type 2 diabetes mellitus but the cognitive domains and patient groups most affected have not been identified.; Objective: To determine whether comorbid depression in patients with type 2 diabetes accelerates cognitive decline.; Design: A 40-month cohort study of participants in the […]
Physical activity reduces hippocampal atrophy in elders at genetic risk for Alzheimer’s disease

Rao, Stephen M.
We examined the impact of physical activity (PA) on longitudinal change in hippocampal volume in cognitively intact older adults at varying genetic risk for the sporadic form of Alzheimer’s disease (AD). Hippocampal volume was measured from structural magnetic resonance imaging (MRI) scans administered at baseline and at an 18-month follow-up in 97 healthy, cognitively intact […]

Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease of motor neurons that results in progressive weakness and death from respiratory failure, commonly within about 3 years. Previous studies have shown association of a locus on chromosome 9p with ALS and linkage with ALS-frontotemporal dementia. We aimed to test whether this genomic region is also […]
