The brain is a major target for the actions of alcohol, and heavy alcohol consumption has long been associated with brain damage. Studies clearly indicate that alcohol is neurotoxic, with direct effects on nerve cells. Chronic alcohol abusers are at additional risk for brain injury from related causes, such as poor nutrition, liver disease, and ...
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 ...
The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol, so once it is in ...
Americans’ relationship with alcohol and their perception of how healthy it is may be changing — with younger people drinking a lot less, and many people in general reevaluating whether even ...
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 (also known as ethanol) has a number of effects on health. Short-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain, several types of cancer and alcohol use disorder. [1] Alcohol intoxication affects the brain, causing slurred ...
Alcoholism does not have uniform effects on all families. The levels of dysfunction and resiliency of non-alcoholic adults are important factors in effects on children in the family. Children of untreated alcoholics have lower measures of family cohesion, intellectual-cultural orientation, active-recreational orientation, and independence.
Alcohol alters consciousness by shifting levels of neurotransmitters. Neurotransmitters are endogenous chemicals that transmit signals across a synapse from one neuron (nerve cell) to another "target" cell (often another neuron). Neurotransmitters can cause inhibitory or excitatory effects on the "target" cell they are affecting. [33]
