Are memory lapses from drinking normal?
Direct Answer
Memory lapses, often called 'blackouts,' are periods of amnesia for events that occurred while intoxicated. These are a symptom of acute alcohol intoxication. It does not indicate that such lapses are a typical or expected outcome of alcohol consumption for everyone, or that they are without potential for harm.
Common Misunderstandings
Many believe a blackout means passing out. A blackout is different; it involves memory loss while still conscious and functional. Some assume that experiencing a blackout is a normal part of heavy drinking. Blackouts indicate a level of intoxication that impairs brain function and memory consolidation.
In Practice
When alcohol is consumed rapidly or in large quantities, it can interfere with the brain's ability to form new memories. This means a person might engage in activities and conversations but later have no recall of them. This is distinct from passing out, where consciousness is lost. The ability to function outwardly during a blackout does not mean brain function is normal. It means the brain's memory-making process is disrupted.
What This Does NOT Mean
This does not mean that every person who drinks alcohol will experience blackouts. This does not imply that experiencing a blackout is harmless. This does not confirm an alcohol use disorder; however, recurrent blackouts can be a sign of problematic drinking patterns. This does not include memory loss from chronic conditions unrelated to acute alcohol consumption.
