The metabolism of ceramides is deregulated in the brain of Alzheimer’s disease (AD) patients and is associated with apolipoprotein (APO) APOE4 and amyloid-β pathology. However, how the ceramide metabolism changes over time in AD, in vivo, remains unknown. Distribution and metabolism of [18F]F-HPA-12, a radio-fluorinated version of the ceramide analog N-(3-hydroxy-1-hydroxymethyl-3-phenylpropyl) dodecanamide, was investigated in the brain of AD transgenic mouse models (FAD) on an APOE4 or APOE3 genetic background, by positron emission tomography and by gamma counter. We found that FAD mice displayed a higher uptake of [18F]F-HPA-12 in the brain, independently from the APOE4 …

Introduction: Microglial cells play an important role in the development of Alzheimer's disease (AD). People with Down syndrome (DS) inevitably develop AD neuropathology (DSAD) by 40 years of age. We characterized the distribution of different microglial phenotypes in the brains of people with DS and DSAD.
Methods: Autopsy tissue from the posterior cingulate cortex (PCC) from people with DS, DSAD, and neurotypical controls was immunostained with the microglial marker Iba1 to assess five microglia morphological types.
Results: Individuals with DS have more hypertrophic microglial cells in their white matter. In the gray matter, individuals with DSAD had significantly fewer ramified …

Introduction: The striatum and frontal lobes have been shown to have early Alzheimer's disease (AD) neuropathology and are critical for motor and cognitive function. We hypothesized gait would be associated with early-stage dementia in Down syndrome (DS), a cohort at risk for AD.
Methods: Twenty-eight participants with DS were enrolled in the study. Participants walked at their self-selected pace and while completing a dual task (counting, obstacle, or counting+obstacle).
Results: All participants were able to complete the self-paced condition and 78.57-96.42% completed the dual-task conditions. There was a trend for greater dual-task effects on gait velocity based on dementia diagnosis. …

We present a consensus atlas of the human brain transcriptome in Alzheimer's disease (AD), based on meta-analysis of differential gene expression in 2,114 postmortem samples. We discover 30 brain coexpression modules from seven regions as the major source of AD transcriptional perturbations. We next examine overlap with 251 brain differentially expressed gene sets from mouse models of AD and other neurodegenerative disorders. Human-mouse overlaps highlight responses to amyloid versus tau pathology and reveal age- and sex-dependent expression signatures for disease progression. Human coexpression modules enriched for neuronal and/or microglial genes broadly overlap with mouse models of AD, Huntington's disease, amyotrophic …

Coronavirus disease 19 (COVID-19) has dramatically altered everyday life, including the field of Alzheimer's disease (AD) research. This perspective article explores some of the ways in which COVID-19 has already impacted the field, anticipates some of the long-lasting effects, and explores strategies for addressing current and future needs. Areas of impact include study integrity, regulatory and industry issues, and participant engagement. Proposed strategies for addressing these challenges include analytic methods to deal with large degrees of missing data and development of patient-centered, user-friendly, remote data collection tools and assessments. We also highlight the importance of maintaining participant well-being as a …

Efficacy Of Cpap Compared To Standard Pharmacotherapy In Reducing Cognitive Impairment Symptoms In Patients With Alzheimer's Disease, Nicholas Moylan
Efficacy Of Cpap Compared To Standard Pharmacotherapy In Reducing Cognitive Impairment Symptoms In Patients With Alzheimer's Disease, Nicholas Moylan
Capstone Showcase
This review analyzed the following question: In adults age 65 years old or older diagnosed with Alzheimer’s Disease (P), is nightly use of CPAP (I) more effective in reducing cognitive impairment symptoms (O) than standard pharmacotherapy options (C)? A literature search conducted through Google Scholar and PubMed granted six relevant articles that provided data for this review. No current studies compared CPAP treatment with pharmacotherapy, and each study used unique measures of cognitive function, making direct comparison of the two therapies difficult. Results demonstrated that first line pharmacotherapy can improve cognitive function, but only in limited way and only in …
