Blackout drunk describes memory loss from heavy alcohol intake. Excessive drinking inhibits the hippocampus, the brain’s memory center, preventing events during intoxication from moving from short-term to long-term storage, resulting in ‘blackouts’. This can be dangerous because the person does not know what they are doing and could hurt themselves or someone else.

There are many symptoms of an alcoholic blackout including slurred speech, stumbling, loss of balance, and vomiting. If you think you or someone you know is blackout drunk, it is important to get help immediately. Treatment for a drunk blackout usually includes therapy and support groups.

How Is Being a Blackout Drunk Different From Binge Drinker?

recovering from blackout drinkingBeing blackout drunk is generally considered to be when a person drinks enough alcohol within 2-3 hours to raise their Blood Alcohol Concentration (BAC) to 0.15%. This usually results in a loss of consciousness for at least a short while. Blackout drinking can also be classified by the number of drinks consumed within a certain amount of time.

  • Four or more drinks in two hours for women
  • Five or more drinks in two hours for men,

For example, heavy drinking is defined as eight or more drinks a week for women and 15 or more drinks a week for men. While blackout drinking can occur during either of these behaviors, it generally happens during binge drinking.

Blackout drinking can also happen without binge drinking. This usually occurs when someone has been drinking heavily over time and their BAC gradually builds up over time.
