Information:
With such effects such as difficulty walking, blurred vision, slurred speech,
and slowed reaction time...it is safe to say alcohol affects the brain.
Most of the hinderances can only be noticed after one or two servings of
alcoholic beverage.
They subside whenever the drinking stops. On the other hand, a person who drinks heavily over a long period of time may have brain deficits that persist even after they are sober.
Blackouts
Alcohol can produce detectable impairments in memory after only a few drinks
and, as the amount of alcohol increases, so does the impairment. Large quantities
of alcohol, especially when consumed quickly and on an empty stomach, can
produce a blackout, or an interval of time for which the intoxicated person
cannot recall key details of events, or even entire events.
Blackouts are much more common among social drinkers than previously assumed and should be viewed as a potential consequence of acute intoxication regardless of age or whether the drinker is clinically dependent on alcohol .
