People experiencing blackouts can appear completely normal to everyone around them, as they are still able to talk and move around. It is only later, when the person who blacked out cannot remember doing or saying things while they were intoxicated, that they realize anything is amiss. Ultimately, the legal system must navigate the intricate interplay between neuroscience, personal responsibility, and public safety when addressing incidents involving alcohol-induced blackouts. Research underscores the importance of further studies to inform both legal discourse and public health strategies.

Alcohol-induced blackouts during the past three months prospectively predicted increased social and emotional negative consequences, but not alcohol dependence symptoms the following year. These findings contradict Jellinek’s theory ecstasy addiction and abuse of alcoholism, which posits that alcohol-induced blackouts are a precursor of alcoholism (Jellinek, 1952). Blackouts become more likely as your blood alcohol concentration reaches a high level quickly, as occurs with binge drinking.
Preventing an Alcohol Blackout
I once asked a group of alcoholics in rehab how many had experienced a blackout in the first years of their drinking. Then I asked those with their hands in the air how many of them had an alcoholic parent. All but two kept their hand up, and one who had lowered his hand said he was adopted and did not know about his parents. There are still plenty of Four Loko flavors available, but the iconic adult energy drink brand voluntarily removed all caffeine from its products back in 2010 due to a string of lawsuits brought against the drink maker. That, and the FDA gave the company notice that caffeine was an unsafe food additive in alcoholic drinks. Almost anyone who had a chance to try a Four Loko before the change can likely attest to that fact.
Types of Blackouts
One brain region that is central to hippocampal functioning is a small structure in the fore brain known as the medial septum (Givens et al. 2000). The medial septum sends rhythmic excitatory and inhibitory signals to the hippocampus, causing rhythmic cbt for alcoholism and drug addiction changes in the activity of hippocampal pyramidal cells. In electroencephalograph recordings, this rhythmic activity, referred to as the theta rhythm, occurs within a frequency of roughly 6 to 9 cycles per second (hertz) in actively behaving rats.
Is a blackout the same as passing out?
With data revealing that nearly half of drinkers experience blackouts, the issue is not confined to a small subset of the population. Individuals experiencing blackouts can engage in complex behaviors yet have no memory of their actions, increasing the risk of injury, risky behavior, and legal problems. Therefore, understanding the mechanisms behind alcohol-induced blackouts is crucial for prevention and intervention strategies geared toward reducing the risk of such occurrences. Although the exact meaning of these changes remains unclear, the evidence suggests that acute intoxication alters the normal functioning of the frontal lobes.
The pervasiveness of this assumption is reflected in numerous writings during the early 20th century. During the 1970s, researchers hypothesized that alcohol depressed neural activity by altering the movement of key molecules (in particular, lipids) in nerve cell membranes. This change then led to alterations in the activity of proteins, including those that influence communication between neurons by controlling the passage of positively or negatively charged atoms (i.e., ions) through cell membranes (e.g., Chin and Goldstein 1977). In some cases, only a few amino acids appear to distinguish receptors that are sensitive to alcohol from those that are not (Peoples and Stewart 2000).
A person may hide alcohol and lie about their drinking habits during this time or become defensive when asked about their drinking. During a blackout, the mind is not functioning properly because the brain is not functioning properly. The fundamental mental dysfunction is that short-term memory is no longer being uploaded into longer-term memory. Short-term memory is sometimes called scratchpad memory—it records events for only about three minutes before they fade. Blackouts are not necessarily a sign of alcohol use disorder, but experiencing even one is a reason for concern and should prompt people to consider their relationship with alcohol and talk to their health care provider about their drinking.
Those who black out may talk to people, drive cars, spend money, have unprotected sex, and more. We offer physician-led treatment for drug and alcohol addiction in Colorado.

If sufficient alcohol is present in the ACSF bathing the slice of hippocampal tissue when the patterned stimulation is given, the response recorded later at position B will not be larger than it was at baseline (that is, it will not be potentiated). And, just as alcohol tends not to impair recall of memories established before alcohol exposure, alcohol does not disrupt the expression of LTP established before alcohol exposure. In a typical LTP experiment, two electrodes (A and B) are lowered into a slice of hippocampal tissue kept alive by bathing it in oxygenated artificial cerebral spinal fluid (ACSF).
Beyond The Beast Unleashed, you can also find its hard tea brand, The Nasty Beast. Since The Nasty Beast line is tea, it has a small amount of natural caffeine, about 21mg per can compared to the 160mg of a regular Monster Energy drink. You’re out celebrating with your pals, throwing back shots and maybe a pint or two from your local brewery. But next thing you know, you wake up feeling groggy, your phone is missing, you can’t find your shoes and you don’t remember how the evening ended.
- Even with cues, you’re unlikely to remember what happened during this time.
- Such outcomes could have important implications for screening and prevention efforts.
- Blackouts are not to be confused with “passing out,” or loss of consciousness.
- As such, future research should use alternative methodologies to better understand the phenomenology of alcohol-induced blackouts.
- Subjects also are normally able to recall long-term memories formed before they became intoxicated; however, beginning with just one or two drinks, subjects begin to show impairments in the ability to transfer information into long-term storage.
- They further tested whether gender moderated the association in a sample of 1,164 college students.
Fragmentary blackouts, also called “grayouts” or “brownouts,” are the most common form of blackout. They are characterized by incomplete memories of events while under the influence of alcohol. These memories can be patchy with clear ‘islands’ of recall, interspersed by periods of amnesia. During such blackouts, individuals might still be able to perform tasks but cannot later recall those actions. For individuals with severe addiction, inpatient rehabilitation may be necessary to provide a structured environment for detoxification and recovery.
For instance, some individuals experience memory impairments after consuming alcohol more frequently than others with similar drinking patterns. This suggests that personal history, including previous blackout experiences and individual neurochemical responses to alcohol, can influence the likelihood of experiencing a blackout. The primary factor in these alcohol-induced blackouts is a significant impairment in the brain’s ability to transfer memories from short-term to long-term storage, a process called memory consolidation, which primarily involves the hippocampus.
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).
Table 6 provides independent predictors of the total number of various alcohol-related problems respondents experienced in the last six months. Blackouts because of drinking was the strongest independent predictor of the total number of alcohol-related problems in the past six months. A comparison of drinkers and non-drinkers in the sample revealed no significant differences in age, sex, race/ethnicity, sexual orientation, or body weight. Not surprisingly, drinkers were significantly more likely than non-drinkers to live away from home and to smoke or use marijuana and other drugs. Alcohol-induced blackouts have several contributing factors related to both drinking behaviors and genetics. Identifying the signs of an alcohol blackout may be difficult, if not impossible.
The most common cause of permanent blackouts is thiamine deficiency due to poor diet in chronic alcoholics, called Korsakoff’s Syndrome. Questions about blackouts during routine medical visits could serve as an important simple screen for the risk of alcohol-related harms. At present, questions about blackouts are not included in most national surveys of alcohol and other drug use. A question about blackouts is included in the full version of the AUDIT.
Binge drinking can quickly develop into a blackout situation, and people sometimes view blacking out as a sign of having fun. However, alcohol blackouts are a serious threat to a person’s health and safety. They increase the risk of other dangerous activities and consequences, such as injury, sexual assault, violence and alcohol poisoning. Although alcohol-induced blackouts were previously thought to occur only in individuals who were alcohol dependent (Jellinek, 1946), we now know that blackouts are quite common among healthy young adults. In fact, approximately 50% of college students who consume alcohol report having experienced an alcohol-induced blackout (Barnett et al., 2014; White et al., 2002). Therefore, this systematic review provides an update (2010–2015) on the clinical research focused on alcohol-induced blackouts, outlines practical and clinical implications, and provides recommendations for future research.
For example, information might be obtained from a research observer, posing as a confederate, who is not drinking but is present at the drinking event. Also, because short-term memory remains intact, use of ecological momentary assessment with smart phones might also be useful for gathering information about the drinker’s experiences while he or she is in a blackout state. Subsequent interviews could then determine what aspects of those events were remembered and whether they were remembered in the same way that they were reported during the drinking event. As detailed in this brief review, alcohol can have a dramatic impact on memory.
Although the mechanism of alcohol-induced blackouts is now known, our understanding of the specific neurobiological vulnerability and why some individuals are more likely to experience alcohol-induced blackouts while others are not has been an area of growing interest. Table 3 reports alcohol problems respondents experienced in the past 6-months according to the frequency with which they experienced a blackout during that time period. Of note, entering body weight into the regression as a predictor of blackouts partially but not completely accounted for the increased risk multiorgan dysfunction related to chronic ketamine abuse pmc of blackouts among women relative to men. The phenomenon of blackouts has gained notoriety, particularly among young adults, with some individuals even reporting the intention to drink to the point of experiencing a blackout. Such behaviors suggest an alarming trend of normalization within certain social circles, potentially exacerbating the risk of more frequent and severe blackouts. It’s evident that beyond the immediate risks of harm and memory loss, alcohol-induced blackouts can have insidious effects on relationships, professional life, and overall well-being.
CBT helps patients develop coping strategies to avoid high-risk drinking situations and manage cravings. Furthermore, memory assessments can be used to determine the extent of cognitive impairments alcohol misuse contributes to, facilitating a tailored treatment plan that addresses specific deficits. 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 abuse or addiction, it is critical to approach treatment with both immediate and long-term strategies in mind. It’s also important to note that experiencing even a single blackout can be a sign of concerning alcohol use and should prompt an evaluation of one’s relationship with alcohol.
