Chronic high dose Alcohol drinking proven to increase Amyloid plaques as Alzheimers disease and Dementia

 Alcohol and Alzheimer's Disease—Does Alcohol Dependence Contribute to Beta-Amyloid Deposition, Neuroinflammation and Neurodegeneration in Alzheimer's Disease? - the question is asked in 2017 as a paper title

A 2020 study said statistically - no relation between alcohol and amyloid plaques 

A 2023 study says alcohol both causes and protects from amyloid plaques as Alzheimer's disease 

 Long-term intake of high-dose alcohol can induce cognitive deficits and improve the activity of β-APP decomposition-related enzymes, increase Aβ content and deposition, and initiate AD progression,

 Amyloid plaques proven to be increased by high dose chronic alcohol drinking

Ethanol Increases Diffuse Amyloid Plaque Load and Impairs Memory in the 5xFAD Mouse Model of Alzheimer's Disease

 A 2025 study confirms the 2021 study - high dose alcohol increases amyloid plaques as Alzheimers Disease 

 pronounced ethanol exposure, when started early in the disease before amyloid pathology is established, can worsen AD progression in an amyloidosis model.

AI says:

High-dose chronic alcohol consumption causes a significant portion of dementia, with studies indicating that up to 38% of early-onset dementia cases are directly linked to alcohol use disorders 

  Alcohol use disorders (AUD) are associated with a three times greater risk of developing all types of dementia.  all types of alcohol use and increased dementia risk.
