Chronic alcohol use can cause lasting damage to the brain, affecting both its structure and function. These effects can be devastating, but understanding them is the first step toward seeking help. In large part, damage done to the brain by alcohol is permanent, a discovery that has more and more people experimenting with their sobriety. However, improvement in these conditions can be achieved the longer sobriety continues. The problem is that many people who drink for extended periods of time find it difficult to quit. In the early stages, alcohol molecules bind to receptors in the brain, stimulating the release of dopamine, a neurotransmitter that makes you feel pleasure.
However, the extent of recovery depends on factors like the duration and severity of alcohol use, age, and overall health. While these short-term effects may seem temporary, repeated episodes of heavy drinking can lead to more severe, long-term consequences. Heavy drinking over time has also been linked to an increased risk of dementia, memory loss, and other cognitive impairments. Studies have found that long-term alcohol misuse can cause permanent damage to nerve cells and even alter their structure. Learning about the long-term effects of alcohol on the brain can be surprising to anyone who has previously thought of alcohol consumption as a relatively safe way to cope with stress.
Can Drinking Alcohol Affect Brain Health and Productivity?
An overdose of alcohol affects the brain’s ability to sustain basic life functions. Multiple episodes of heavy drinking can have long-term consequences for memory. Research shows that heavy drinking can speed up memory loss and cognitive decline compared with those who did not drink, had quit drinking, or were light-to-moderate drinkers. This complication of long-term heavy drinking causes scarring of the liver. Scar tissue impairs the liver’s ability to create proteins, filter the blood, and other bodily functions. Research shows that there’s no safe level of alcohol consumption.
Does Alcohol Permanently Damage the Brain?
Alcohol disrupts normal brain function, leading to lowered inhibitions, impulsive behavior, and difficulty focusing or making decisions. It is important to always consume in moderation and to seek care if you exceed your limits. Alcohol causes irritation and inflammation along your gastrointestinal (GI) tract, disrupting normal alcohol effects in the brain: short and long terms digestive function. Evidence suggests that certain alcoholic beverages, such as wine and beer, appear to accelerate the movement of food and waste through the digestive system, which can lead to diarrhea.
The hippocampus is the area of the brain responsible for memory and learning. In 2013, Dr. Hoffnung established Reintegrate, an outpatient Medication-Assisted Treatment (MAT) opioid addiction clinic in Madison, where he has successfully helped over 1000 patients in their recovery. As safe alcohol consumption varies from person to person, and different sources recommend various intakes, it is important to take an individualized approach. People should talk to a healthcare professional about their drinking history and personal risk factors to get tailored advice on safe alcohol consumption.

Other hazards include increased dependency, depression, anxiety and severe withdrawal symptoms when the alcohol leaves your bloodstream. For the brain to function properly, the FDA recommends consuming alcohol in moderation. If you feel you’re at risk of suicide due to heavy drinking, consult a mental health professional. A doctor can recommend the appropriate treatment program and prescribe addiction medicine.
- The short-term effects of alcohol develop quickly—within minutes after your first drink—impacting mood, coordination, speech, memory, and behavior.
- Scientifically, alcohol acts as a relaxant, working on a system called the GABA system.
- Permanent memory issues, including alcohol-related dementia, can happen after extended use.
- So, the alcohol builds up quite quickly,” explains addiction psychiatrist Akhil Anand, MD.
Understanding Inpatient vs. Outpatient Mental Health Treatment: What’s Best for You?
Alcohol misuse leads to cognitive, physiological, and structural changes in several cortical and sub-cortical structures. Neuroactive drugs such as ethanol influence neurotransmission to alter mood. Long-term alcohol use can lead to addiction, the compulsion to take the drug and loss of control over intake, or dependence, the need for continued drug exposure to avoid withdrawal. Tolerance, where a reduced effect follows repeated exposure to a constant dose, or an increased dose is needed maintain the same effect, is also common (see Tolerance and Dependence).
- Blackouts are gaps in a person’s memory of events that occurred while they were intoxicated.
- However, with the right support and treatment, recovery is possible.
- Following Wernicke’s encephalopathy, the person may develop signs of Korsakoff syndrome.
- Newer studies are also uncovering how alcohol may interfere with the immune system and accelerate molecular signs of aging.
Why Does Alcohol Consumption Lead to Bad Decisions?
By Lindsay CurtisCurtis is a writer with over 20 years of experience focused on mental health, sexual health, cancer care, and spinal health. Alcohol poisoning can quickly become life-threatening and requires prompt medical treatment. Call 911 for help if you suspect someone is experiencing alcohol poisoning. Symptoms can vary from person to person, so it’s best to exercise caution and seek medical help if someone you are with shows signs of extreme alcohol intoxication.
Women tend to weigh less than men and are enzymatically prone to not processing alcohol as quickly. Therefore, they’re more likely to feel the acute effects of alcohol sooner. That means that after enough exposure, it shrinks both individual neurons and the entire brain. When particular regions of the brain, such as the hippocampus, are chronically exposed to alcohol, memory, mood, behavior, and cognition suffer. It can also disrupt sleep — a separate pathway for cognitive impairment. If drinking too much ruins your sleep, you may wake up with a double dose of brain fog.
The first syndrome (Wernicke’s encephalopathy) is a short-lived but severe syndrome that can cause cognitive impairment and problems with the central nervous system. The second syndrome (Korsakoff’s psychosis) is a chronic, debilitating syndrome that causes significant brain damage. Alcohol is a diuretic, meaning it increases urine production and can lead to dehydration. Dehydration can adversely affect brain function, causing symptoms such as headache, dizziness, and confusion.
Alcohol affects the hippocampus, which helps create new memories in your brain. This contributes to blackouts and short-term memory lapses when drinking. Research has shown that men and women experience alcohol-induced blackouts at equal rates, although women drink less often and heavily than men. Support groups, such as Alcoholics Anonymous (AA), provide peer support and shared experiences in a group setting.
