Does blackouts cause brain damage?

Blackouts – especially if they are happening frequently – are a sign that something more serious is happening and may certainly impact your memory and long term brain function. While blackouts seem to have a connection to heavy drinking, the amount alone is not enough to cause temporary memory loss.

What does blacking out from alcohol do to your brain?

Alcohol interferes with receptors in the brain that carry signals between neurons, causing some brain cells to then manufacture steroids that prevent memory formation. When a person is blacked out, the brain continues to process information but is incapable of forming new memories due to this reaction.

What happens to your brain when you black out?

During a blackout, the hippocampus in the brain is unable to form long-term memories. As a result, a person can fail to remember large chunks of time despite being conscious. Everyone experiences an alcohol blackout differently.

How do you know if alcohol has damaged your brain?

Difficulty walking, blurred vision, slurred speech, slowed reaction times, impaired memory: Clearly, alcohol affects the brain. Some of these impairments are detectable after only one or two drinks and quickly resolve when drinking stops.

What causes brain blackouts?

Most unexplained blackouts are caused by syncope Many people, including doctors, assume that blackouts are due to epileptic seizures, but much more commonly they are due to syncope (pronounced sin-co-pee) – a type of blackout which is caused by a problem in the regulation of blood pressure or sometimes with the heart.

Why do I blackout so easily?

One of the biggest causes of a blackout from drinking is consuming too much too fast. When you drink alcohol rapidly, your liver cannot keep up and metabolize the alcohol fast enough. This causes blood alcohol concentration levels to rise quickly until you reach the point of an alcohol blackout.

Is it possible to get brain damage from drinking alcohol?

  • Although brain damage could potentially occur from heavy alcohol consumption, there is no evidence that blackouts are caused by brain damage per se. However, if brain damage is caused from excessive alcohol use, some studies show improvements in brain function with as little as a year of abstinence.

What happens to your brain when you have a blackout?

  • Aside from short bursts of heavy drinking, drinking heavily over a long time period (I mean years) can affect the brain and cause lasting damage including, but not limited to, slips in memory. These memory slips can be due to lack of blood flow to brain areas that are important for memory consolidation and are more commonly known as blackouts.

Why do people have blackouts after binge drinking?

  • Many people who experience blackouts do so because of binge drinking but they can also occur when people combine certain medications (like benzodiazepines) and alcohol. 1
