What are blackouts without daily drinking?
Direct Answer
Alcohol-induced blackouts involve memory loss for events that occurred while intoxicated. The individual is typically conscious and functional during a blackout. This does not necessarily mean daily alcohol consumption is required for blackouts to occur.
Common Misunderstandings
["Some people mistakenly believe a blackout means losing consciousness. A blackout is a memory gap. The person can be interactive and appear normal.","It is sometimes thought that blackouts only happen to individuals with severe alcohol dependence. Blackouts can occur after consuming a sufficient amount of alcohol, regardless of drinking frequency.","The idea that blackouts are a choice is inaccurate. Blackouts are an impaired brain function caused by rapid alcohol intake, affecting memory encoding."]
In Practice
A person might attend a social event, drink alcohol, and later have no recollection of parts of the evening. They may have conversed, driven, or performed other complex actions. These actions are not remembered the next day.
What This Does NOT Mean
["This does not mean the individual was unconscious. They were typically awake and interacting with their environment.","This does not mean the person is necessarily an 'alcoholic' or has an 'alcohol use disorder'. While blackouts can be a sign of problematic drinking, they can also occur in individuals who drink infrequently but consume alcohol rapidly.","This does not include simply forgetting minor details. A blackout involves significant periods of amnesia for events that transpired."]
