While rare, alcohol-induced psychosis is a condition that causes a heavy drinker to experience symptoms similar to schizophrenia or psychosis. It can be very serious and warrants the attention of a medical professional immediately. 

What Is Alcohol-Induced Psychosis?

Alcohol-induced psychosis describes a state some people who struggle with chronic alcohol use disorder may experience where a person experiences a break from reality caused by the use of alcohol.[1] It generally presents after heavy alcohol use for a long period of time. The condition is not fully understood, but it is likely linked to neurotransmitters such as dopamine and serotonin.

Signs & Symptoms of Alcohol-Induced Psychosis

Alcohol-induced psychosis is primarily characterized by auditory hallucinations.[2] A person may also experience delusions and disturbances in their mood. A person may also experience visual hallucinations and even the sensation that someone or something is touching them.

An individual experiencing this type of psychosis is at higher risk of suicide and self-harm. They should be monitored for their own safety. If you are experiencing this condition, it’s important to alert someone you trust or a mental health professional about these thoughts, so they can help you address them in a healthy way.

In many ways, this condition mimics schizophrenia: A patient may experience racing thoughts, hear voices, see things that are not actually there, or endorse delusions about things happening that aren’t real.

In others, it is often easiest to notice alcohol-induced psychosis by radical changes to their mood and demeanor, as well as individuals talking to themselves as if someone else is with them. They may also have trouble sleeping and seem distracted.[2]

Treatment For Alcoholic Psychosis

Research on alcohol-induced psychosis is limited, and more needs to be done to determine what treatments are most effective. The first step is usually to stop the alcohol. This should be done in a carefully monitored setting, usually in the hospital.

Others may need antipsychotic medication in order to stop their hallucinations. What might cause this difference is again not fully understood. For some people, even antipsychotic medication appears ineffective, and their hallucinations may continue despite treatment.[3]

Any new episode of psychosis in a person drinking heavily should prompt friends or loved ones to seek urgent medical care. The person should go to the emergency room, and may need to be admitted to the hospital for monitoring and medications to help ease their symptoms.
