CONTEXT The hallmark pathological changes in Alzheimer disease (AD) are abundant plaque and tangle formation, especially in the temporal lobes and hippocampus. Although there is increasing evidence that major depression may interact with neuropathological processes in AD, there have been no studies of neuropathological changes in AD as a function of history(More)
Although amnestic mild cognitive impairment (aMCI; often considered a prodromal phase of Alzheimer's disease, AD) is most recognized by its implications for decline in memory function, research suggests that deficits in attention are present early in aMCI and may be predictive of progression to AD. The present study used functional magnetic resonance(More)
Rapid rise in the population of older adults in India will lead to the need for increased health care services related to diagnosis, management, and long-term care for those with dementia and cognitive impairment. A direct approach for service provision through memory clinics can be an effective, successful, and sustaining means of delivering specialized(More)
Cardiovascular risk factors including hypertension (HTN) have been shown to increase the risk of Alzheimer disease. The current study investigated whether individuals with HTN are more susceptible to increased cognitive decline and whether the influence of HTN on cognitive decline varied as a function of dementia severity. A total of 224 nursing home and(More)
OBJECTIVE Executive dysfunction, possibly related to vascular pathology, has been well documented in patients with a first episode of major depressive disorder in later life (late-onset geriatric major depression). However, it is unclear whether the neuropsychological presentation differs in patients with a lifetime history of major depressive disorder(More)
OBJECTIVE To test the hypothesis that use of antihypertensive medication is associated with lower Alzheimer disease (AD) neuropathology. METHODS This was a postmortem study of 291 brains limited to those with normal neuropathology or with uncomplicated AD neuropathology (i.e., without other dementia-associated neuropathology) in persons with or without(More)
OBJECTIVE To examine the association between treatment for diabetes and Alzheimer disease (AD) neuropathology. METHODS This postmortem study matched 124 subjects with diabetes to 124 without diabetes from the Mount Sinai School of Medicine Brain Bank, on age (mean = 81.2 + 9.3), sex (57.3% F), and severity of dementia (Clinical Dementia Rating [CDR] 2.4 +(More)
BACKGROUND Advanced glycations end products increase oxidant stress, inflammation, and neurotoxicity. Serum levels are increased in diabetes and aging. We examined the relationship between serum methylglyoxal derivatives (sMG), and cognitive decline, in 267 non-demented elderly. METHODS Tobit mixed regression models assessed the association of baseline(More)
OBJECTIVE To compare the diagnostic accuracy of CSF biomarkers and amyloid PET for diagnosing early-stage Alzheimer disease (AD). METHODS From the prospective, longitudinal BioFINDER study, we included 122 healthy elderly and 34 patients with mild cognitive impairment who developed AD dementia within 3 years (MCI-AD). β-Amyloid (Aβ) deposition in 9 brain(More)
Visual cortical surface area varies two- to threefold between human individuals, is highly heritable, and has been correlated with visual acuity and visual perception. However, it is still largely unknown what specific genetic and environmental factors contribute to normal variation in the area of visual cortex. To identify SNPs associated with the(More)
