There is noobjective evidence that a person is in an alcohol-induced blackout (Pressman and Caudill, 2013), thus it can be difficult orimpossible to know whether or not a drinker is experiencing a blackout (Goodwin, 1995). This is similar to the factthat one cannot know whether another person has a headache; the experience ishappening inside that person’s brain, with no clear observable indices. Perhaps the greatest impediment to rigorous tests of alcohol-inducedblackouts and behavior is that researchers are not ethically permitted toprovide alcohol in sufficient doses to cause a blackout to occur. BrACs of 20g/dl and above are typically required to induce a blackout, thereby limiting theability to safely dose research participants to the point of blackout. Finally,given the growing literature on alcohol-induced memory impairments andblackouts, a standardized assessment for alcohol-induced blackouts is sorelyneeded.
During a blackout, an intoxicated person can still function as normal. They may seem articulate because most parts of the brain are alcohol-tolerant. They can still eat, walk, hold conversations, have sex, drive, and get into fights. The speed with which short-term memory is formed depends on the amount of theta rhythm (7-13 Hertz) organizing the hippocampus.
Theta rhythm comes from areas in the midline of the lower parts of the brain. In Korsakoff’s, these source areas of theta are destroyed, which leaves the hippocampus disorganized enough that the link between short- and long-term memory is severed. It is not difficult to navigate through an evening with full awareness of your life before the blackout began and of only what happened in the last three minutes since the blackout began. The gap in memory between the beginning of amnesia and the last three minutes continues to grow as long as the blackout lasts. There is a lot of information during the last three minutes, enough to keep people oriented and appearing quite normal, even to themselves.
- These effects range in severity from momentary “slips” in memory to permanent, debilitating conditions.
- The strategy may cover areas such as mental health, suicide prevention, heart disease and stroke.
- Aside from the sex differences, there could be a genetic component to who is more likely to blackout.
- Despite the increase in research on and our understanding ofalcohol-induced blackouts, additional rigorous research is still needed.
Let’s talk about your recovery
The next day, you probably woke up dehydrated with a headache and a hangover. But you could probably remember everything you did, with a little effort and reminders. THC, the psychoactive compound found in marijuana, may also increase blackouts when combined with alcohol.

They are a significant health concern, as they are not simply a sign of general intoxication but indicate a temporary disruption in the brain’s ability to transfer memories from short-term to long-term storage. 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.

Number of published journal articles or reviews that evaluate alcohol-inducedblackouts per year (1985 to 2015). The graph represents published articles andreviews published in English and includes both animal and human studies with theterms “blackout” and “alcohol” in the title,abstract, and/or keyword. A comprehensive, systematic literature review was conducted toexamine all articles published between January 2010 through August 2015 thatfocused on examined vulnerabilities, consequences, and possible mechanismsfor alcohol-induced blackouts.
Alcohol Blackouts: Signs, Causes, And Dangers Of Blacking Out
Fragmentary blackouts typically preserve short-term memory functioning and some episodic memories. In contrast, en bloc blackouts present a more extensive disruption, sparing neither short-term nor episodic recall for the duration of the blackout. Although our understanding ofalcohol-induced blackouts has improved dramatically, additional research isclearly necessary.
And a study of 2,000 participants one year out of secondary school found that, of the 68% who admitted having ever had a drink, 20% reported they had experienced a blackout in the previous six months. They are smaller on average than men and have a higher percentage of body fat, which means their bodies have less water to dilute the alcohol they drink – so their blood alcohol level rises faster. In 2017, Amie Haas of Palo Alto University in California found that women would routinely blackout with three fewer drinks than men. liquor storage ideas for small spaces A 2015 study showed that women who consumed only one more drink than their usual amount had a 13% higher chance of blacking out than men. We now also know more about other factors that influence blackouts, such as drinking on an empty stomach or when sleep deprived. Another major risk has to do with how fast alcohol is consumed, as the quicker we gulp the faster our blood alcohol level spikes.
Identifying an alcohol blackout can be difficult because you may still engage in normal behaviors like driving a car, spending money, talking to others, or having sex. You just won’t remember what you did the next day because your memories have not formed or been transferred to long-term memory storage. 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.
As the word suggests, in this state all memories of the night turn dark after a point. Some drinkers experience less severe, fragmentary blackouts where only pieces of memory are lost. Although the connections are not yet fully understood, there is little doubt alcohol can affect memory and other cognitive functions, both in the short and long term. Still, the most effective and simple strategy to prevent alcohol-induced blackouts is to avoid large amounts of the substance, especially in combination with other drugs or medications. In humans the amount of alcohol that triggers a blackout varies from person to person. Those who drink large amounts quickly, however, tend to experience memory impairment more often.
