What are 'blackouts' from drinking?
Direct Answer
Alcohol-induced amnesia, commonly known as a blackout, refers to gaps in memory for events that occurred while intoxicated. During a blackout, an individual can appear fully conscious and interact with others. This does not necessarily mean unconsciousness, stupor, or coma.
Common Misunderstandings
People sometimes believe blackouts mean passing out. Blackouts involve memory impairment, not necessarily loss of consciousness. Another misunderstanding is that blackouts only happen with extreme alcohol consumption. They can occur at varying blood alcohol concentrations, depending on individual factors. Some may think blackouts are a choice to forget. They are a physiological response to alcohol's effect on memory formation.
In Practice
When a person experiences a blackout, their brain temporarily loses the ability to form new long-term memories. Events during this period are not stored in the brain's memory system. For example, a person might have a conversation or drive a car. Later, they will have no recollection of these actions or events. Others present during a blackout might not notice anything unusual about the person's behavior. The person might appear to be functioning normally.
What This Does NOT Mean
This does not mean the person was unconscious or unable to function. It does not mean they intentionally forgot events. It does not signify a failure of 'willpower'. It does not guarantee alcohol dependence or addiction for every instance. It refers to a specific type of memory impairment caused by alcohol.
