Alcohol hallucinosis is a rather uncommon alcohol-induced psychotic disorder almost exclusively seen in chronic alcoholics who have many consecutive years of severe and heavy drinking during their lifetime. [3] Alcoholic hallucinosis develops about 12 to 24 hours after the heavy drinking stops suddenly, and can last for days.
Psychoactive substance-induced psychotic disorders outlined within the ICD-10 codes F10.5—F19.5: F10.5 alcohol: [8] [9] [10] Alcohol is a common cause of psychotic disorders or episodes, which may occur through acute intoxication, chronic alcoholism, withdrawal, exacerbation of existing disorders, or acute idiosyncratic reactions.

The DSM-5 classifies Korsakoff syndrome under Substance/Medication-Induced Major or Mild Neurocognitive Disorders, specifically alcohol-induced amnestic confabulatory. [8] The diagnostic criteria defined as necessary for diagnosis includes prominent amnesia, forgetting quickly, and difficulty learning.
Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol.

[ 12 ] Withdrawal seizures: seizures occur within 48 hours of alcohol cessation and occur either as a single generalized tonic-clonic seizure or as a brief episode of multiple seizures.
The mechanism of alcohol-related psychosis is due to the long-term effects of alcohol consumption resulting in distortions to neuronal membranes, gene expression, as well as thiamine deficiency. It is possible that hazardous alcohol use via a kindling mechanism can cause the development of a chronic substance-induced psychotic disorder, i.e ...

The mechanism of alcohol-related psychosis is due to distortions to neuronal membranes, gene expression, as well as thiamin deficiency. It is possible in some cases that excessive alcohol use, via a kindling mechanism, can cause the development of a chronic substance-induced psychotic disorder, i.e. schizophrenia.
