Naltrexone and acamprosate are examples of medications used to reduce the desire to drink. Additionally, treatment for any physical health issues resulting from excessive alcohol use is essential. 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. If you or someone you know frequently experiences blackouts, consider seeking support from a medical professional or an addiction specialist to explore treatment options and strategies for reducing alcohol consumption. By adhering to moderate drinking guidelines and recognizing individual responses to alcohol, one can reduce the likelihood of experiencing these memory impairments. Additionally, educating yourself about the risks and effects of alcohol can be an effective preventive measure.
Symptoms Associated With Different Levels of Intoxication
Blacking out is a scary and often unintended consequence of heavy drinking or binge drinking. If you experience blackouts, otherwise known as alcohol-related memory loss, you are not alone. Research shows that as many as 50 percent of people who drink experience blackouts. With the right information, time, and support, you can stop experiencing blackouts for good.
Alcohol-Related Blackouts
- 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.
- Given the powerful influence that the medial septum has on information processing in the hippocampus, the impact of alcohol on cellular activity in the medial septum is likely to play an important role in the effects of alcohol on memory.
- While blackouts are a frightening experience, treatment can allow people to lead a normal life without the fear of falling unconscious or losing their memory.
- Additionally, educating yourself about the risks and effects of alcohol can be an effective preventive measure.

How much alcohol can cause a blackout?
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. There are two types of blackouts; they are defined by the severity of the memory impairment. The most common type is called a “fragmentary blackout” and is characterized by spotty memories for events, with “islands” of memories separated by missing periods of time in between.
In classic studies of hospitalized alcoholics by Goodwin and colleagues (1969a,b), 36 out of the 100 patients interviewed indicated that they had never experienced a blackout. In some ways, the patients who did not experience blackouts are as interesting as the patients who did. What was it about these 36 patients that kept them from blacking out, despite the fact that their alcoholism was so severe that it required hospitalization? Although they may actually have experienced blackouts but simply were unaware of them, there may have been something fundamentally different about these patients that diminished their likelihood of experiencing memory impairments while drinking. Wetherill and colleagues (2012)conducted a follow-up study that used a within subject alcohol challengefollowed by two functional magnetic resonance imaging (fMRI) sessions under noalcohol and alcohol (target BrAC of .08 g/dl) conditions. Overall, these findings suggestthat alcohol-induced blackouts can have profound effects on anindividual’s overall health and well-being, above and beyond the effectsof heavy alcohol consumption.
Alcohol, Memory, and the Hippocampus
A 2015 survey of English teenagers who drank showed 30 percent of 15-year-olds and 75 percent of 19-year-olds suffered alcohol-induced blackouts. Heavy alcohol use contributes to a shrinkage of the brain similar to Alzheimer’s disease, which is characterized by memory loss. However, studies do not support alcohol as a cause of Alzheimer’s disease.
This information will enable researchers to statistically control forthe direct effects of alcohol consumption and examine factors that influencealcohol-induced blackouts over and beyond the amount of alcohol consumed. In support of this possibility, a recent study by Hartzler and Fromme (2003a) suggests that people with a history of blackouts are more vulnerable to the effects of alcohol on memory than https://sober-house.org/cbt-and-dbt-in-alcohol-addiction-treatment/ those without a history of blackouts. These authors recruited 108 college students, half of whom had experienced at least one fragmentary blackout in the previous year. While sober, members of the two groups performed comparably in memory tasks. However, when they were mildly intoxicated (0.08 percent BAC) those with a history of fragmentary blackouts performed worse than those without such a history.
Among other things, he investigates how alcohol damages the brain and which substances protect the nerve cells from the drug. People who are blacked out are likely to continue drinking because the substance jeopardizes their judgment. They may not remember how much they have consumed, so they continue drinking excessively. Alcohol poisoning and death from alcohol overdose are direct consequences of drinking too much alcohol.
And, according to new research, this could actually be changing the structure of our brains, particularly in areas related to learning and memory. Psychologically, blackouts can result in feelings of depression or anxiety regarding alcohol use and lost memories. As long as excessive drinking continues, these immediate symptoms may extend into chronic mental health conditions. 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. They’re also more common among university students, who are known to ‘pre-game’ to get “a buzz on before they start to socialise, and that makes your blood alcohol level rise fast”, says Hingson.
Most of the research conducted on blackouts during the past 50 years has involved surveys, interviews, and direct observation of middle-aged, primarily male alcoholics, many of whom were hospitalized. Researchers have largely ignored the occurrence of blackouts among young social drinkers, so the idea that blackouts are an unlikely consequence of heavy drinking in nonalcoholics has remained deeply entrenched in both the scientific and popular cultures. Yet there is clear https://sober-home.org/alcohol-effects-in-the-brain-short-and-long-terms/ evidence that blackouts do occur among social drinkers. Knight and colleagues (1999) observed that 35 percent of trainees in a large pediatric residency program had experienced at least one blackout. Similarly, Goodwin (1995) reported that 33 percent of the first-year medical students he interviewed acknowledged having had at least one blackout. “They drank too much too quickly, their blood levels rose extremely quickly, and they experienced amnesia” (p. 315).
“Anything that causes damage to the brain, whether temporary or permanent, can cause memory loss if the damage is in the right spot,” states Dr. Streem. THC, the psychoactive compound found in marijuana, may also increase blackouts when combined with alcohol. According to the National Institute on Alcohol Abuse and Alcoholism, alcohol delays signals in the brain that control the gag reflex and other autonomic responses. A person who has blacked out or overdosed on alcohol could throw up while sleeping due to the loss of reflex control. It’s important to remember that a blackout isn’t the same as passing out. Someone who passes out has either fallen asleep or become unconscious because they consumed too much alcohol.
In one he showed participants pornography, then asked detailed questions about what they had seen. In another, with a frying pan in hand, he asked individuals if they were hungry. The drunk subjects had forgotten these memories after 30 minutes and could still not recall the events the following day. They could, though, recall these events up to two minutes later, revealing that their short-term memory was working. Research conducted in the past few decades using animal models supports the hypothesis that alcohol impairs memory formation, at least in part, by disrupting activity in the hippocampus (for a review, see White et al. 2000b).
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 the difference between mdma ecstasy and molly 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). 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.
