Alcohol-related psychosis arises from distortions to neuronal membranes, gene expression, and thiamine deficiency in some cases. There is evidence that excessive alcohol use via a kindling mechanism can occasionally cause the development of chronic substance-induced psychosis [142] that may transition to schizophrenia in predisposed individuals ...
