Clinical and neuropathological staging of Alzheimer’s disease (AD) neurodegeneration and neuronal loss dynamics is the baseline for identification of treatment targets and timing. The aim of this study of 14 brain regions in 25 subjects diagnosed with AD and 13 age-matched control subjects was to establish the pattern of neurodegeneration, and the...
Article
Older adults (65+) are among the fastest growing segments of the population, projected to double by 2050. Oldest‐old (85+) manifest the greatest relative increase in population and have the greatest risk of developing Alzheimer’s Disease (AD). Depression is a chronic, debilitating condition in older adults. Depressive symptoms, particularly apathy—...

We published results of a clinician‐blind, parallel‐group study of Comprehensive, Individualized, Person‐Centered Management (CI‐PCM) in moderate‐to‐severe, community‐residing, Alzheimer’s persons (Reisberg…Kenowsky, Dement Geriatr Cogn Disord, 2017). CI‐PCM intervention subjects (n=10) showed 967% greater global improvement than subjects randomize...
Article
Neuropsychological tests are useful in the assessment of cognitive functioning, but whites have consistently performed better than other racial/ethnic groups. The utility of some of these tests has not been fully established for Hispanic elderly, and especially among relatively highly educated Spanish‐speaking Hispanics. Seventy‐five pairs of Spani...

Background: We have described the clinical stages of the brain aging and Alzheimer's disease (AD) continuum. In terms of the pre-dementia stages of AD, we introduced the terminology "mild cognitive impairment" (MCI) for the first pre-dementia stage and "subjective cognitive decline" (SCD) for the pre-MCI stage. We now report the characteristics of...

IMPORTANCE: Mutations in known causal Alzheimer disease (AD) genes account for only 1% to 3%of patients and almost all are dominantly inherited. Recessive inheritance of complex phenotypes can be linked to long (>1-megabase [Mb]) runs of homozygosity (ROHs) detectable by single-nucleotide polymorphism (SNP) arrays. OBJECTIVE: To evaluate the associ...

Full-text available
Research increasingly suggests that subjective cognitive decline (SCD) in older adults, in the absence of objective cognitive dysfunction or depression, may be a harbinger of non-normative cognitive decline and eventual progression to dementia. Little is known, however, about the key features of self-report measures currently used to assess SCD. Th...

Full-text available
Recently, a rare variant in the amyloid precursor protein gene (APP) was described in a population from Iceland. This variant, in which alanine is replaced by threonine at position 673 (A673T), appears to protect against late-onset Alzheimer disease (AD). We evaluated the frequency of this variant in AD cases and cognitively normal controls to dete...

Background: It has been shown that amyloid ß (Aβ), a product of proteolytic cleavage of the amyloid β precursor protein (APP), accumulates in neuronal cytoplasm in non-affected individuals in a cell type-specific amount. Methodology/principal findings: In the present study, we found that the percentage of amyloid-positive neurons increases in su...
Data
Neurons with low and high amyloid load. In control brains, the percentage of Aβ-positive neurons and their amyloid load is much lower in CA1 than in CA4 sector and is very low in the granule neurons in the dentate gyrus. The percentage of Aβ-positive neurons and amyloid load is significantly higher in the dup(15) autism cohort than in the control a...

Summary“Staging methods have been applied to dementia for nearly 175 years. Currently, two different dementia staging procedures are widely used. These are the Clinical Dementia Rating (CDR) and the Global Deterioration Scale (GDS) Staging System. The latter include, in addition to the GDS staging, the Functional Assessment Staging (FAST) and the B...
