Upon his death, histology revealed that the loss of blood to R.B.’s brain damaged a small region of the hippocampus called hippocampal area CA1, which contains neurons known as pyramidal cells because of the triangular shape of their cell bodies (Zola-Morgan et al. 1986). Hippocampal CA1 pyramidal cells assist the hippocampus in communicating with other areas of the brain. The hippocampus receives information from a wide variety of brain regions, many of them located in the tissue, called the neocortex, that blankets the brain and surrounds other brain structures. As is clear from patient R.B., removing CA1 pyramidal cells from the circuitry prevents the hippocampal memory system from doing its job. Despite the increase in research on and our understanding ofalcohol-induced blackouts, additional rigorous research is still needed.
Blackouts and Your Brain: How To Avoid Memory Loss
If a person drinks on an empty stomach or quickly consumes a lot of alcohol, their BAC level could increase faster than usual. Blackouts can happen to anyone who drinks too much, regardless of age or experience drinking. For those whose blackouts have led to dangerous or risky behavior, it may also be necessary to address legal or social solution based treatment and detox consequences through additional counseling or community services. Ultimately, a combination of these treatments, tailored to the individual’s specific needs, can improve the chances of a successful recovery from alcohol-induced blackouts. Alcohol-induced blackouts are memory gaps for events that occur while you’re intoxicated.
How we reviewed this article:
In the U.S., nearly 14 million women had an average of three binges a month, six drinks at a time. (Six? My quota was more like 16.) I told myself this report was just another form of woman-shaming by our patriarchal society. The difference between a brownout and a blackout is that brownouts involve partial memory loss. With a brownout, you may be able to remember certain details from the period of time you were affected, but other portions of time can’t be recalled. We are currently investigating which substances strengthen long-term potentiation under the influence of alcohol and thus support the formation of memories.
Let’s talk about your recovery
Additionally, treatment for any physical health issues resulting from excessive alcohol use is essential. Individuals who frequently experience alcohol-induced blackouts often require a multi-faceted approach to treatment, which may include both medical and psychological interventions. Recognizing that regular occurrences of blackouts can be indicative of alcohol use disorder (AUD), it is critical to approach treatment with both immediate and long-term strategies in mind. While blackouts don’t directly cause harm by themselves, drinking to the extent that you black out can have serious consequences.
Blackouts occurred in five of the seven subjects, as evidenced by an inability to recall salient events that occurred while drinking the day before (e.g., one subject could not recall preparing to hit another over the head with a chair). Estimates of BAC levels during blackout periods suggested that they often began at levels around 0.20 percent and as low as 0.14 percent. Based on is baclofen addicting his observations, Ryback concluded that a key predictor of blackouts was the rate at which subjects consumed their drinks. 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.
Can you recover memories lost during a blackout?
Schuckit’s study and several others have found that people who black out from drinking risk a number of negative consequences. People who experience a fragmentary blackout may think they can’t remember what happened the night before, but their memory comes back when someone or something reminds them. Researchers believe a person may be unable to access the memory unless a reminder triggers it.
Blackouts can happen to anyone who drinks alcohol, regardless of their age or experience with drinking. Haas and colleagues showed that women who experienced blackouts were more likely to engage in risky sexual behaviour while in a blackout state, compared to men and to drinkers who didn’t blackout at all. One longitudinal study of adolescents aged 12-21, led by Reagan Wetherill of the University of Pennsylvania, showed that certain individuals who later went on to abuse alcohol and experience blackouts, were less able to suppress their actions. This could be seen on brain scans, even before they were drinking alcohol. In rats, White showed that there are doses of alcohol where brain cells “still kind of work”, and higher doses where they are completely off – which explains partial blackouts where only fragments are lost.

Although our understanding ofalcohol-induced blackouts has improved dramatically, additional research isclearly necessary. By fine-tuning our approach to studying blackouts, we willimprove our understanding of alcohol-induced blackouts, and consequently, bebetter situated to improve prevention strategies. Several factors affect the likelihood that information will be transferred into long-term memory. For decades, researchers have known that alcohol disrupts the brain’s ability to transfer memories from short-term to long-term memory, but they didn’t know how. The common consensus was that alcohol killed brain cells, causing memory loss and other cognitive impairments. These effects range in severity from momentary “slips” in memory to permanent, debilitating conditions.
A doctor may prescribe fludrocortisone to reduce blackouts in people who experience neurally mediated syncope. A cardiac syncope is more serious as it could signal an underlying problem with the heart. Tachycardia, bradycardia, or other types of hypotension could cause a cardiac syncope. If a person does not get treatment, they are at risk of complications or even sudden cardiac death. According to the National Institute on Alcohol Abuse and Alcoholism, a very high blood-alcohol concentration may result in a person struggling to remain conscious. In the most severe cases of alcohol intoxication, they may even fall into a coma.
- Though these experiments were performed with alcoholics, they set the stage for understanding how even non-alcoholics act during a blackout.
- Alcohol-related blackouts are gaps in a person’s memory for events that occurred while they were intoxicated.
- The latter study found that women experienced the side effects after drinking only half as much as men.
- One study found that the frequency with which people had gotten drunk in general in the last month was a risk factor for whether someone experienced a blackout.
A second interpretation is that subjects in the blackout group performed poorly during testing as a result of drinking enough in the past to experience alcohol-induced memory impairments. In other words, perhaps their prior exposure to alcohol damaged the brain in a way that predisposed them to experiencing future memory impairments. This latter possibility is made more likely by recent evidence that students who engage in repeated episodes of heavy, or binge, drinking are more likely than other students to exhibit memory impairments when they are intoxicated (Weissenborn and Duka 2000).
Subsequent interviews could then determine what aspects ofthose events were remembered and whether they were remembered in the same waythat they were reported during the drinking event. A general model of memory formation, storage, and retrieval based on why do alcoholics get red noses the modal model of memory originally proposed by Atkinson and Shiffrin (1968). Alcohol seems to influence most stages of the process to some degree, but its primary effect appears to be on the transfer of information from short-term to long-term storage.
