Alcohol Psychosis: How Alcohol Can Cause Paranoia & Hallucinations
Contrary to popular belief, psychosis is not a mental health condition. Psychosis is a state that can either exist as a symptom of a psychotic disorder, like schizophrenia or be brought on by certain substances, including alcohol. In most instances, alcohol-induced psychosis ends when the symptoms of alcohol consumption or withdrawal subside. However, in cases of prolonged use, psychosis can be long-lasting or life-threatening. Because of this, it’s crucial that anyone experiencing alcohol-induced psychosis or exhibiting the early signs of an alcohol use disorder receive professional treatment.
Alcoholic hallucinosis is a rare condition that usually arises after years of chronic, severe alcohol abuse. While other forms of alcohol-induced psychosis may involve visual and tactile hallucinations, those associated with alcoholic hallucinosis are primarily auditory and usually occur during or shortly after periods of heavy alcohol consumption. Alcoholic hallucinosis may also involve delusions and mood disturbances. The periods of psychosis characteristic of alcoholic hallucinosis may last for a matter of hours, days or weeks, or progress to a chronic, long-lasting form that mimics schizophrenia.
Also referred to as delirium tremens, symptoms of AWD may include any of the following:
- Extreme sensitivity to light, sound or touch
- Sudden changes in mood
- Increased heart and breathing rates
- Formication, or the feeling that tiny insects are crawling on or under the skin
- Body tremors
Delirium tremens is one of the most potentially dangerous side effects of alcohol withdrawal. These symptoms tend to be life-threatening and require professional medical attention. Because of this, it’s crucial that any individual undergoing alcohol withdrawal do so under the supervision of a medical detox program.
Telling the difference between alcohol-related psychosis and schizophrenia can be difficult, as they share many of the same symptoms. Fortunately, alcohol-induced psychosis has characteristics that distinguish it from schizophrenia, including:
- Later onset of symptoms
- More depressive and anxiety symptoms
- Fewer negative and disorganized symptoms
- Less functional impairment
Individuals with an alcohol-use disorder tend to have more success when medical detox is undergone as part of a continuum of care because they can gradually develop the skills needed to maintain lifelong recovery.
A continuum of care includes:
- Medical detox
- Inpatient programs
- Partial hospitalization
- Intensive outpatient
- Outpatient programs
While psychosis can develop temporarily as the result of excessive alcohol consumption, it may also be a symptom of a co-occurring psychotic disorder, like schizophrenia, schizoid personality disorder or schizotypal personality disorder. In these cases, a dual diagnosis alcohol treatment program that addresses both the alcohol use disorder and psychological condition is crucial to long-term recovery.
- Prolonged or excessive alcohol use can lead to temporary psychosis
- Alcohol-induced psychosis typically manifests as acute intoxication, alcohol hallucinosis or AWD
- While the exact cause of alcohol-induced psychosis is unknown, it is thought to be related to the way that excessive alcohol consumption affects the brain and body
- While alcohol can cause temporary psychosis, it typically does not cause long-term psychosis
- When psychosis persists for an extended period after alcohol use has stopped, it is often a sign of a co-occurring mental health condition
- Professional care is crucial for any individual experiencing alcohol-induced psychosis, as this is usually a sign of an alcohol use disorder
