Additionally, one may consider visiting Substance Abuse and Mental Health Services Administration (SAMHSA) treatment locator to find resources in their area. If a person uses it heavily long-term, they’re at risk for a number of memory-related health conditions. Alcohol affects short-term memory by slowing down how nerves communicate with each other in a part of the brain called the hippocampus. These situations can range from small, such as where a person put their keys, to large, such as forgetting what happened in night. According to Duke University, the inability to remember anything from a night out usually occurs after a person has had five or more drinks. Some people experience what doctors call a blackout when they drink too much alcohol and don’t remember key details.
Types of Blackouts
There may be ways to lessen alcohol’s effects on memory by reducing the amount of alcohol consumed and by using memory techniques to overcome memory loss issues. The brain possesses an impressive ability to repair brain damage from alcohol, thanks to a phenomenon known as brain plasticity or neuroplasticity. This enables the brain to recover from damage and adapt to new patterns of thinking and behavior. During the detoxification process, which is the initial step in recovery, these healing mechanisms are set in motion, and noticeable changes can often be observed within a couple of weeks. Sustained long-term sobriety can ultimately restore optimal mental function and full brain recovery from alcohol abuse. The link between alcohol and memory loss is just one of many concerns that may arise from alcohol misuse.
Interrupted Memories: Alcohol-Induced Blackouts
A small amount of current is passed through electrode A, causing the neurons in this area to send signals to cells located near electrode B. Electrode B then is used to record how the cells in the area respond to the incoming signals. Next, a specific pattern of stimulation intended to model the pattern of activity that might occur during an actual learning event is delivered through electrode A. When the original stimulus that elicited the baseline response is delivered again through electrode A, the response recorded at electrode B is larger (i.e., potentiated). In other words, as a result of the patterned input, cells at position B now are more responsive to signals sent from cells at position A. The potentiated response often lasts for an extended period of time, hence the term long-term potentiation.
Brain Recovery from Alcohol: FAQs
He stated, “It is important to note that all the blackout periods occurred after a rapid rise in blood alcohol level” (p. 622). The two subjects who did not black out, despite becoming extremely intoxicated, experienced slow increases in blood alcohol levels. In a subsequent study, White and colleagues (2004) interviewed 50 undergraduate students, all of whom had experienced at least one blackout, to gather more information about the factors related to blackouts. As in the previous study, students reported engaging in a range of risky behaviors during blackouts, including sexual activity with both acquaintances and strangers, vandalism, getting into arguments and fights, and others. During the night of their most recent blackout, most students drank either liquor alone or in combination with beer. Only 1 student out of 50 reported that the most recent blackout occurred after drinking beer alone.
Seeking professional help and support during the recovery process can optimize your brain’s chances of regaining its health and functionality. The extent of recovery depends on various factors, though, including the https://sober-home.org/cbt-for-alcoholism-and-drug-addiction-does-it-work/ severity and duration of alcohol abuse, individual differences, and the presence of any underlying conditions. Additionally, many older people also experience a slow degeneration of the cells in the hippocampus.
- This part, the hippocampus, can’t do its memory-producing job when alcohol levels increase beyond 0.16%, which is about twice the legal limit.
- For example, many studies have demonstrated the profound cognitive deficits frequently seen in some alcoholics during withdrawal.
- Alcoholics must be able to practice with specific behaviors in treatment that reduce risk until these behaviors are as automatic as possible.
- Was able to retrieve long-term memories formed roughly a year or more before his surgery, he could not recall events that transpired within the year preceding his surgery.
- It can also cause the prefrontal cortex to shrink and degrade, potentially impairing decision-making skills and social behavior.

The second common misconception is that having a blackout is characteristic of an alcohol use disorder more commonly called alcoholism — that you only have blackouts if you have an alcohol use disorder. If you’re unable to control how much you drink, avoid drinking altogether. If you have experienced a blackout before, you’re likely at a higher risk for blacking out in the future and should exercise caution. Popular media and some celebrities with drug problems glamorize blacking out, and not being able to remember what happened the night before is the topic of many fun-filled tales. But blackouts are no laughing matter, according to expert researcher Dr. Marc Schuckit.
Having interviewed many people now about their lives, Dimity sees how people open up when given the time and space to do so. “If you know somebody has a history of abuse in their marriage, then you’re not going to reminisce with them about their wedding dress,” she says. But she cautions that reminiscence therapy must be done delicately, keeping in mind potential traumas in a person’s past. The app enabled this information to be stored and, with permission, shared with family members and other carers. But to deliver person-centred care, you have to know a little about who that person is. Doctors, nurses and carers can benefit from this reminiscence therapy too.
This strongly suggests that the transfer of information into long-term storage actually takes place over several years, with the hippocampus being necessary for its retrieval for the first year or so. During the 2 weeks preceding the survey, an equal percentage of males and females experienced blackouts, despite the fact that males drank significantly more often and more heavily than females. This outcome suggests that at any given level of alcohol consumption, females—a group infrequently studied in the literature https://sober-home.org/ on blackouts—are at greater risk than males for experiencing blackouts. The greater tendency of females to black out likely arises, in part, from well-known gender differences in physiological factors that affect alcohol distribution and metabolism, such as body weight, proportion of body fat, and levels of key enzymes. There also is some evidence that females are more susceptible than males to milder forms of alcohol-induced memory impairments, even when given comparable doses of alcohol (Mumenthaler et al. 1999).
If at the first test, group two performs better than group one, then time-dependent recovery is evident. Repeat testings are necessary to ensure that differences between the supposedly matched groups are not the result of unintended discrepancies between the groups (e.g., differences in premorbid intelligence). The difference in the rate of improvement between the alcoholics and the nonalcoholics is then an indication of the “true” recovery of cognitive functioning.
Abstinence also can help reverse negative effects on thinking skills, including problem solving, memory, and attention. While quitting altogether provides the greatest benefit, the authors say that even cutting back to a low risk level can help and could be a more achievable goal for those with alcohol use disorder. Research suggests that both quitting and cutting back on your alcohol consumption can provide benefits for your brain by reducing the amount of shrinkage in certain regions. “The intention is for individuals to experience support and a sense of community on their journey toward healthier drinking habits,” said English. She also suggests joining a peer-support community like Lionrock.life where you can gain support and advice from other people who are also working to reduce their drinking. Sometimes we may regain partial memories, but this depends on a number of different factors such as our age, how long we’ve been drinking, and how much we’ve been drinking.
In addition, alcoholics have not consistently shown learning and memory deficits despite the fact that more severe versions of these impairments are symptoms of Wernicke-Korsakoff syndrome (see Parsons et al. 1987). According to the National Council on Alcoholism and Drug Dependence, females are at particular risk for blackouts. This is because females tend to weigh less than males and have less water in their bodies to dilute alcohol levels. They also have less of an enzyme called alcohol dehydrogenase in the gut that breaks down a small percentage of alcohol before it even gets into the body. Females also are more likely to skip meals to save calories when they drink, so there is less food in the stomach to help absorb the alcohol. As a result, more alcohol reaches the brain, where it plays havoc with sensory and memory functions.

The results were published in the Quarterly Journal of Studies on Alcohol. These descriptions of alcohol-induced deficits derive primarily from the researchers’ intuitive analyses of what the tests seem to measure, such as abstracting ability or memory. Some investigators use more sophisticated strategies based on cognitive psychology to better understand the nature of the cognitive dysfunctions.

Medications are available for some substances to help support the detox and withdrawal process. Our brains have an incredible ability to adapt and repair – even after prolonged AOD use and addiction. The brain’s reward system is designed to reinforce positive experiences (such as eating, socialising and sex), so you’ll do it again.
The only way he would know is if somebody later told him that something happened while he was intoxicated and he didn’t remember it, and then he believed they were telling the truth. So it’s not a particularly easy question to answer unless you know the definition of blackout and your memory has been questioned, or somebody told you about it. Still, several studies link heavy alcohol use to learning and memory problems. It’s unclear whether blacking out causes serious long-term damage, but heavy alcohol use and risky behaviors while blacked out can have serious long-term health effects. Short-term effects of alcohol abuse — such as coordination problems, slurred speech and blurry vision — fade when alcohol is metabolized, which can take hours or days. Other studies have found using benzodiazepines such as Valium and Rohypnol alongside alcohol greatly increase the chances of a blackout.
