Content: The most common cause of a complete or partial blackout is alcohol. When you drink while taking other drugs, a blackout is even more likely. Frequent alcohol-related blackouts might be a sign of problem drinking. If you or someone you know has blackouts that involve loss of memory or consciousness and you don’t know why, see a doctor right away. Blackouts can be a sign of a serious medical condition. How Does Alcohol Cause Blackouts? If you usually stop after a drink or two, then you’ve probably never had an alcohol-related blackout. They usually happen when people drink too much too fast. Consuming excessive alcohol can lead to gaps in memory. Those gaps form because the alcohol prevents short-term memories from becoming long-term memories.
