What Is an Alcohol Blackout?
Many people ask, “What is an alcohol blackout?”
When someone drinks too much, their brain stops being able to make new memories. It’s possible that the person is still awake and talking or walking. In the end, though, they don’t remember what they said or did.
Going out is not the same as this. A person is awake during a blackout, but they can’t remember things.
How Alcohol Affects the Brain
Drinking alcohol slows down the brain. It affects areas that control thinking, judgment, and memory.
When alcohol enters the body:
- It reaches the brain through the blood.
- It slows brain signals.
- It affects memory storage.
Alcohol blocks the brain from saving short-term memories into long-term memory. This is how blackouts happen.

Alcohol Blackout Causes
There isn’t just one reason. Most of the time, more than one thing works together.
Drinking Too Much, Too Fast
The most common cause of alcohol blackout is drinking large amounts quickly.
When alcohol enters the blood too fast:
- The brain cannot adjust.
- Memory shuts down
- Blackouts are more likely.
Shots and other strong drinks quickly make you drunker.
Drinking on an Empty Stomach
Alcohol gets into the blood more slowly when you eat. When you drink without eating, the booze hits your brain more quickly.
This increases the risk of:
- Blackouts
- Nausea
- Loss of control
High-Alcohol Drinks
Some drinks have much more alcohol.
Examples include:
- Shots
- Mixed drinks with strong liquor
- Energy drinks mixed with alcohol.
Even with a few drinks, these drinks can make you lose consciousness.
Body Size and Health
Everyone reacts to alcohol differently.
Risk factors include:
- Smaller body size
- Low tolerance
- Being very tired
- Dehydration
- Certain medications
All of these can make blackouts more likely.
Mixing Alcohol With Other Substances
Using alcohol with drugs or medications is very dangerous.
This can:
- Increase memory loss
- Slow breathing
- Increase overdose risk
Mixing substances greatly raises blackout risk.
