Alcohol-related dementia can produce a variety of psychiatric problems including psychosis (disconnection from reality), depression, anxiety, and personality changes. Patients with alcoholic dementia often develop apathy, related to frontal lobe damage, that may mimic depression. [3] People with an alcohol use disorder are more likely to become ...
Using statistical methods based on genetic analyses, the authors of the study found that alcohol heightened dementia risk in proportion to the amount of alcohol consumed. This study contradicts ...
Alcohol abuse affects neurons in the frontal cortex that typically have a large soma, or cell body. This type of neuron is more susceptible to Alzheimer's disease and normal aging. Research is still being conducted to determine whether there is a direct link between excessive alcohol consumption and Alzheimer's disease. [8]
Alcohol acts as a general central nervous system depressant, but it also affects some specific areas of the brain to a greater extent than others. Memory impairment caused by alcohol has been linked to the disruption of hippocampal function—particularly affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation ...
Alzheimer’s disease impacts more than six million Americans, but the exact cause of the devastating condition is still being investigated by scientists. Now, new research has found a new risk ...
Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens, [2] and is the cause of 60–70% of cases of dementia. [2][15] The most common early symptom is difficulty in remembering recent events. [1] As the disease advances, symptoms can include problems with language, disorientation (including ...
The Nun Study of Aging and Alzheimer's Disease is a continuing longitudinal study, begun in 1986, to examine the onset of Alzheimer's disease. [1] [2] David Snowdon, an Epidemiologist and the founding Nun Study investigator, started the Nun Study at the University of Minnesota, later transferring the study to the University of Kentucky in 1990.

The biochemistry of Alzheimer's disease, the most common cause of dementia, is not yet very well understood. Alzheimer's disease (AD) has been identified as a proteopathy: a protein misfolding disease due to the accumulation of abnormally folded amyloid beta (Aβ) protein in the brain. [1] Amyloid beta is a short peptide that is an abnormal ...
