Recovering alcoholics and dating
The short-term effects of alcohol (also known formally as ethanol) consumption – due to drinking beer, wine, distilled spirits or other alcoholic beverages – range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses.
Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream, it can diffuse into nearly every cell in the body.
It has been asserted that GABA signals interfere with both the registration and the consolidation stages of memory formation.
As the GABA system is found in the hippocampus (among other areas in the CNS), which is thought to play a large role in memory formation, this is thought to be possible.
This causes reward systems in the brain to become more active, which may induce certain individuals to behave in an uncharacteristically loud and cheerful manner.
Alcohol causes the osmoreceptors to signal that there is low osmotic pressure in the blood, which triggers an inhibition of the antidiuretic hormone.The amount of alcohol consumed largely determines the extent of hangovers, although hydration also plays a role.After excessive drinking, stupor and unconsciousness both can occur.The GABA system is known to inhibit activity in the brain.GABA could also be responsible for causing the memory impairment that many people experience.
