Alcoholic hallucinosis is a condition characterized by hallucinations that occur in individuals with a history of alcohol use disorder. It is a type of alcohol withdrawal syndrome and is distinct from delirium tremens, another severe form of alcohol withdrawal.

Symptoms

The primary symptom of alcoholic hallucinosis is the presence of hallucinations, which are typically auditory but can also be visual or tactile. These hallucinations usually occur within 12 to 24 hours after the last drink and can last for several days. Unlike delirium tremens, alcoholic hallucinosis does not typically involve autonomic instability or altered mental status.

Pathophysiology

The exact mechanism of alcoholic hallucinosis is not fully understood, but it is believed to be related to the sudden cessation of alcohol intake in individuals with chronic alcohol dependence. This leads to an imbalance in neurotransmitter systems, particularly involving gamma-aminobutyric acid (GABA) and glutamate, which can result in the development of hallucinations.

Diagnosis

Diagnosis of alcoholic hallucinosis is primarily clinical and involves a thorough history and physical examination. It is important to differentiate it from other causes of hallucinations, such as schizophrenia or substance-induced psychotic disorder.

Treatment

Treatment of alcoholic hallucinosis involves supportive care and the use of benzodiazepines to manage withdrawal symptoms. In some cases, antipsychotic medications may be used to control severe hallucinations. It is also crucial to address the underlying alcohol use disorder through counseling and rehabilitation programs.
