The more you drink, the more likely it is to affect the hippocampus. Because blackouts tend to occur at high BACs, they commonly stem from binge drinking. The National Institute on Alcohol Abuse and Alcoholism defines binge drinking as a pattern of drinking alcohol that brings BAC to 0.08%—or 0.08 grams of alcohol per deciliter—or higher. For a typical adult, this pattern corresponds to consuming five or more drinks (male), or four more more drinks (female), in about two hours. In the United States, a “standard drink” is defined as any beverage containing 0.6 fl oz or 14 grams of pure alcohol.
Can you recover memories lost during a blackout?
- Alcohol-induced blackouts can have serious consequences that extend far beyond just a fuzzy memory.
- These approaches focus on sustaining abstinence or reducing drinking to safe levels, providing a holistic approach to recovery.
- The more alcohol that is consumed, the higher the level of memory loss will be.
- Blackouts are dangerous events, as the individual basically loses the ability to be cogent or aware of their actions.
This could happen if someone drinks on an empty stomach or consumes large amounts of alcohol in a short amount of time. Because females, on average, weigh less than males and, pound for pound, have less water in their bodies, they tend to reach higher peak BAC levels than males with each drink and do so more quickly. This helps explain why being female appears to be a risk factor for having blackouts. There are two types of blackouts; they are defined by the severity of the memory impairment.
Rehab Resources
Short-term memory is sometimes called scratchpad memory—it records events for only about three minutes before they fade. The best way to regain control is through evidence-based, compassionate addiction treatment. For those who frequently experience alcohol-induced blackouts, treatment is a critical step toward recovery and preventing further damage. Treatment options may include behavioral therapies, medications, and lifestyle modifications. Blackouts are not to be confused with “passing out,” or loss of consciousness.

Similarly, binge drinkers, or someone who drinks a lot in a short period of time, may rapidly raise their blood-alcohol level and black out more often. Alcohol-induced blackouts are defined as amnesia, or memory loss, for all or part of a drinking episode. This memory loss can be sputtering, called fragmentary, or continuous, called en bloc.
Alcohol Blackout: Types Of Alcoholic Blackouts, How They Work, and Consequences
All of these therapies work toward assisting the client to change their behaviors by guiding them toward recognizing disordered thinking and addiction behavior responses. Blackouts are dangerous events, as the individual basically loses the ability to be cogent or aware of their actions. In most cases, the individual will pass out from intoxication and sleep off the effects of the alcohol, but in the morning may remember nothing about a specific period of time from the prior night. The amount and speed at which one drinks alcohol are closely connected to the occurrence of alcohol-induced blackouts. When blood alcohol concentrations (BACs) rise rapidly — such as with binge drinking or drinking on an empty stomach — cognitive abilities become significantly impaired.
Alcohol quantity and the rate of drinking can contribute to these blackouts. Therefore, not only are blackouts damaging to the brain and body, they can also cause someone to engage in risky behavior and not even remember it. We all have either done something drunk and not remembered or know someone who has.
- These biological variances underscore the importance of understanding personal limits and drinking responsibly.
- This is sufficient time for all short-term memory to be lost without transfer to long-term memory.
- These memories can be patchy with clear ‘islands’ of recall, interspersed by periods of amnesia.
- Severe alcohol withdrawal can be deadly, so heavy alcohol users should not attempt to wean off alcohol without the help of a professional medical detox facility.
- These experiences underscore the potent impact that excessive alcohol intake can have on cognitive functions.
- We have the sensory memory, which lasts a few seconds, the short-term memory, which lasts a handful of minutes, and the long-term memory, also known as storage, which can last forever.
Interrupted Memories: Alcohol-Induced Blackouts
Alcohol-induced blackouts, characterized by temporary memory loss, are alarming episodes that can occur alcohol and aggression during or after excessive alcohol consumption. These incidents often involve the inability to recall events that transpired while under the influence despite the individual appearing conscious and capable of interaction at the time. During a blackout, crucial brain functions are disrupted, particularly the process of transferring memories from short-term to long-term storage, affecting the hippocampus.
Getting blackout drunk puts you at risk of physical and sexual violence. You may unwittingly go along with whatever someone else wants—even if that’s stealing, vandalizing someone’s house, or sleeping with someone you never planned to. If your friend, or anyone else, seems blackout drunk, keep alcoholism treatment a close eye on them. Since they’re mentally and physically impaired, they could easily get into trouble.

Angry Drunk Psychology: Why Does Alcohol Make Some People Abusive?
Identical twins share 100 percent of their DNA, while fraternal twins only share 50 percent. There are also family groups that are designed to aid the family members in their support of their loved one’s recovery journey. Understanding the role of family therapy as a dimension of the overall healing picture is essential to recovery success.
- Many people use alcohol socially and are able to avoid drinking too much.
- Binge drinking, defined as consuming four or more drinks in a two-hour period for women and five or more drinks for men, is also a significant risk factor for blackouts.
- Because blackouts tend to occur at high BACs, they commonly stem from binge drinking.
- Someone with blackouts should seriously consider cutting back their alcohol use or seeking help for addiction.
- One way to help a friend or family member struggling with their drinking is by noticing how much they drink.
- Fragmentary blackouts, the most common type, present as spotty memories with discernible gaps.
- Then I asked those with their hands in the air how many of them had an alcoholic parent.
Blackouts also make it difficult to establish meaningful connections with others. If someone repeatedly experiences alcohol-induced memory loss, they may find themselves unable to forge lasting bonds or maintain healthy friendships. Others may become wary of spending time with them due to concerns about their behavior while intoxicated. In social settings, alcohol blackouts can lead to embarrassing or even dangerous situations.
