Impact of Alcohol on the Onset and Progression of Alzheimers Disease and Its Related Dementias (R01 - Clinical Trial Optional)

Funding Opportunity RFA-AA-20-006 from the NIH Guide for Grants and Contracts. The goal of this FOA is to support basic and clinical research on the influence of alcohol on susceptibility and progression of Alzheimers disease and its related dementias. Recent longitudinal studies have provided strong evidence that alcohol use disorder is associated with the high risk of all types of dementias, and frequent heavy drinking increases risk of both Alzheimers disease and vascular dementia. Even moderate alcohol consumption may be a risk factor for adverse brain outcomes and cognitive decline. Although these studies link heavy and frequent alcohol drinking to dementias in aging populations, mechanisms contributing to this relationship are not well understood. With this FOA, we solicitate research projects that combine diverse expertise and use innovative approaches to investigate mechanisms by which alcohol affects brain aging processes to produce dementias and influences development of Alzheimers disease. This FOA strongly encourages collaborations between alcohol researchers and experts in Alzheimer's disease and its related dementia research.

DiscussionMR found robust evidence of a causal association between alcohol consumption and an earlier AAOS, but not alcohol intake and LOAD risk. The protective effect of alcohol dependence is potentially due to survivor bias.

What exactly is psychosis? What happens in the brain of a person with schizophrenia who is hallucinating? Schizophrenic Rachel Star Withers shares her personal hallucinations and delusions and Dr. Joseph Goldberg, who specializes in researching what goes on in the brain when someone is experiencing psychosis, joins to break down how the brain functions during psychotic episodes. Host Rachel Star Withers, a diagnosed schizophrenic, and co-host Gabe Howard delve into these intense subjects in this episode of Inside Schizophrenia.  Highlights from “Psychosis in Schizophrenia” Episode [02:13]  Rachel, do...

This study was designed to test the hypothesis that nondependent alcohol drinking exacerbates the onset and magnitude of AD-like neural and behavioral pathology. We first evaluated the impact of voluntary 24-h, two-bottle choice home-cage alcohol drinking on the prefrontal cortex and amygdala neuroproteome in C57BL/6J mice and found a striking association between alcohol drinking and AD-like pathology. Bioinformatics identified the AD-associated proteins MAPT (Tau), amyloid beta precursor protein (APP), and presenilin-1 (PSEN-1) as the main modulators of alcohol-sensitive protein networks that included AD-related proteins ...

Conclusion and Relevance: Benzodiazepine use in older people from the general population is related to subsequent occurrence of cognitive dysfunction but not implicated in the pathogenesis of dementia or AD. Caution should be exercised when prescribing benzodiazepines to preserve global cognitive function. PMID: 31595772 [PubMed - as supplied by publisher]

This study, as well as other research on the connection between diet and sugary beverages and health risks, is observational and cannot show cause and effect. That’s a major limitation, researchers say, as it’s impossible to determine whether the association is due to a specific artificial sweetener, a type of beverage, obesity or another hidden health issue. “The cause behind these associations isn’t clear,” said Bergquist. “Other potential biological causes could be attributed to experimental evidence linking consumption of artificial sweeteners to sugar cravings, appetite stimulation ...
