Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
The long-term impact of alcohol on the brain has become a growing area of research focus. While researchers have found that moderate alcohol consumption in older adults is associated with better cognition and well-being than abstinence, [1] excessive alcohol consumption is associated with widespread and significant brain lesions.
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 ...
Anxiety increases aldosterone, [36] which must have evolved because of the time delay involved in migration of aldosterone into the cell nucleus. [38] Thus, there is an advantage to an animal's anticipating a future need from interaction with a predator, since too high a serum content of potassium has very adverse effects on nervous transmission.
Diagnosing alcohol-related dementia can be difficult due to the wide range of symptoms and a lack of specific brain pathology. [3] The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) is a guide to aid doctors in diagnosing a range of psychiatric disorders, and may be helpful in diagnosing dementia.
Water accounts for 75% of brain mass, so it makes sense that dehydration would throw a wrench in your brain’s ability to function. One 2023 study found dehydration to reduce cognitive function ...
Alcoholic polyneuropathy is a neurological disorder in which peripheral nerves throughout the body malfunction simultaneously.It is defined by axonal degeneration in neurons of both the sensory and motor systems and initially occurs at the distal ends of the longest axons in the body.
According to a survey published in March, 87% of Americans are concerned about age-related memory loss and a decline in brain function as they grow older, yet only 32% believe they can take action ...
