The difference is that alcoholic women reported that they had been drinking excessively for only about half as long as the alcoholic men in these studies. This indicates that women’s brains, like their other organs, are more vulnerable to alcohol–induced damage than men’s . Alcohol is a depressant, which means it slows down brain functioning and neural activity. Heavy drinking alters a person’s mood, behavior, and neural functioning. Alcohol depresses the nervous system and can produce an array of cognitive impairments. If continued over an extended period of time, alcohol use can lead to memory loss or brain damage.


One of the simplest ways to improve memory and communication is to rehearse information they need to remember. Chris Elkins worked as a journalist for three years and was published by multiple newspapers and online publications. Since 2015, he’s written about health-related topics, interviewed addiction experts and authored stories of recovery. Chris has a master’s degree in strategic communication and a graduate certificate in health communication.

In some cases, only a few amino acids appear to distinguish receptors that are sensitive to alcohol from those that are not . It remains unclear exactly how alcohol interacts with receptors to alter their activity. There is no satisfactory treatment for alcoholic amnestic disorder.

Of this number, less than half received therapy for their addiction. What are the health effects of not drinking alcohol for one month? A promising study that looks at what one month free of booze can do to your body. Alcohol withdrawal syndrome occurs when someone who has been drinking excessive amounts of alcohol for an extended period of time suddenly stops drinking or reduces their intake. Symptoms can develop just 5 hours after the last drink and persist for weeks. Many of these alcohol treatment program options are offered at our inpatient rehab centers.

Reversible causes of memory loss

Verywell Mind uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Read our editorial process to learn more about how we fact-check and keep our content accurate, reliable, and trustworthy. Other National Institutes of Health reports have shown that abstaining from alcohol over several months to a year may allow structural brain changes to partially correct. Abstinence also can help reverse negative effects on thinking skills, including problem­ solving, memory, and attention. Prospective memory is day-to-day brain function, specifically, remembering to complete daily activities. The first is called a partial blackout, and this can happen with just a relatively small amount of alcohol.

When a person continues to drink a high volume of alcohol for extended periods, the toxin begins to slowly destroy the body. If not stopped, alcohol can critically affect a person’s mental and physical faculties. In a typical LTP experiment, two electrodes are lowered into a slice of hippocampal tissue kept alive by bathing it in oxygenated artificial cerebral spinal fluid .

Your doctor can screen you for conditions that cause reversible memory impairment. Experts recommend that a medical workup for memory loss or other cognitive changes always include questions about an individual’s alcohol use. Anyone admitted to the hospital for an alcohol-related condition should be professionally screened for memory loss and cognitive change. The screening should include supplementary questions to assess recent memory. If screening suggests impairment, the person should receive a more detailed cognitive workup.

Effects of Alcohol on Memory

For this reason, as described by Medscape, there is suspicion of a genetic element that could be involved in development of the condition. A study from the International Journal of Geriatric Psychiatry indicates there are other, problematic behavioral symptoms that can occur with alcoholic amnestic disorder, including aggression, agitation, and depression. However, not much is known about how these symptoms are connected and whether or not there are ways to support individuals with these symptoms.


This is believed to be the primary mechanism underlying the effects of alcohol on LTP, though other transmitter systems probably are also involved . During the first half of the 20th century, two theoretical hurdles hampered progress toward an understanding of the mechanisms underlying the effects of alcohol on memory. More recent research has cleared away these hurdles, allowing for tremendous gains in the area during the past 50 years. Scientists have established that the “shrinkage” that alcohol can cause in some regions of the brain that results in cognitive damage will begin to reverse when alcohol stays out of the body for lengthening periods of time. Just as physical activity keeps your body in shape, activities that engage your mind help keep your brain in shape.

For example, these patients can discuss in detail an event in their lives, but an hour later might not remember ever having the conversation. The symptoms of Wernicke’s encephalopathy include mental confusion, paralysis of the nerves that move the eyes (i.e., oculomotor disturbances), and difficulty with muscle coordination. For example, patients with Wernicke’s encephalopathy may be too confused to find their way out of a room or may not even be able to walk. In fact, studies performed after death indicate that many cases of thiamine deficiency–related encephalopathy may not be diagnosed in life because not all the “classic” signs and symptoms were present or recognized.

Lack of recall for the events 24 hours later, while sober, represents clear experimental evidence for the occurrence of blackouts. For all but one subject in the blackout group, memory impairments began during the first few hours of drinking, when BAC levels were still rising. The average peak BAC in this group, which was roughly 0.28 percent, occurred approximately 2.5 hours after the onset of drinking. Figure 1A general model of memory formation, storage, and retrieval based on the modal model of memory originally proposed by Atkinson and Shiffrin . 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.

  • (A corresponding BAC in humans would be twice the legal driving limit in most States.) As the figure illustrates, the cell’s activity was essentially shut off by alcohol.
  • Drug addiction, and abuse are all linked to elevated mortality rates in specific populations.
  • Drinking alcohol can also have negative effects on the peripheral nervous system .
  • In a subsequent study, White and colleagues interviewed 50 undergraduate students, all of whom had experienced at least one blackout, to gather more information about the factors related to blackouts.
  • Because alcohol can be challenging to stop alone, many people will need to participate in a formal treatment program to overcome their addiction.

It is like a delivery truck on a route that gets sidetracked and never makes it to its destination. The delivery never made it; a person simply cannot remember things. Most chronic heavy drinkers display some level ofmemory loss and cognitive impairmentover time. If you drink heavily, you may need medical support for when you decide to stop drinking to prevent potentially severe withdrawal symptoms. Your doctor may suggest admitting you to a hospital or alcohol treatment facility to help. You can avoid short-term memory loss by removing alcohol from the equation.

Hopefully, future work will reveal more regarding the ways in which the effects of alcohol on multiple transmitter systems interact to disrupt memory formation. Permanent memory loss and damage to memory and learning centers is a life-changing situation. People who struggle with this condition are likely to need ongoing care to function. Many people who develop this condition are not diagnosed until it has reached a dangerous point. Because of the severity of this condition’s effect on quality of life and long-term health, it is important to recognize the risks of this disorder and stop drinking alcohol if the risk of developing Wernicke-Korsakoff syndrome is high.

When to get help for memory loss

When a signs of alcoholism drinks excessively or ingests a large amount of alcohol, they enter into a blackout state. Research suggests that binge drinking takes place in about two hours and is characterized by four or more drinks for women and five or more drinks for men. Although the quantity of alcohol a person consumes has a substantial role in causing this condition, researchers think how and how quickly it is finished also has an important function. A complete blackout is when a person will be unable to recall events even if they try hard, as memory loss is irreversible.

Most seizures are spontaneous and brief yet self-limiting and can involve loss of consciousness, a range of unusual movements, odd feelings and sensations or changed behaviour. In a 1970 experiment, researchers in the Washington University School of Medicine’s psychiatry department gave 10 men with a history of alcohol addiction 16 to 18 ounces of 86-proof bourbon in a four-hour period. Despite advice from experts and beer commercials, most people do not drink responsibly. More than 50 percent of adults have blacked out at least once in their lives.

It’s important to note that most researchers and healthcare providers have found that alcohol consumed in moderation — one to two drinks for men and one for women — doesn’t typically affect memory. Some people are tempted by untried or unproven “cures” that claim to make the brain sharper or prevent dementia. Be cautious of pills, supplements, brain training computer games, or other products that promise to improve memory or prevent brain disorders. Currently there is no drug or treatment that prevents Alzheimer’s or related dementias. Content on this website is provided for information purposes only.

The individual who is confabulating to fill in missing information may not be lying in the literal sense of the word. Instead, the person may truly believe that the confabulated memories are real. There is little understanding of why confabulation occurs in Wernicke-Korsakoff syndrome. The MRI research revealed that alcohol abstinence led to brain volume increases in key areas including the frontal lobe and cerebellum.
