Abstract

This study compares patients with acute methamphetamine psychosis to those with chronic methamphetamine psychosis and it investigates how the two groups differ in terms of psychosomatic findings, social background, and so on. The subjects consisted of 100 outpatients diagnosed at our clinic as having methamphetamine-induced psychosis over a period of sixteen years (1979 to 1995). Of these patients, 73 were of the acute type (currently using the drug or totally abstinent for less than 3 months), and 27 were of the chronic type (totally abstinent from the drug from 2 to 38 years). Psychosomatic Findings Ninety five patients (68 acute-type and 27 chronic-type) were classified into six clinical clusters, depending on which of the following states was dominant: paranoid-hallucinatory state, schizophrenia-like state, short-tempered and impulsive state, manic-depression-like state, neurosis-like state, and permanent-encephalopathic state. In the clinical cluster of paranoid-hallucinatory state, all 32 patients were of the acute-type. On the other hand, of those patients in the clinical cluster of neurosis-like state, the majority (N = 25) were of the chronic-type. Social Background The social background of 99 patients (72 acute-type and 27 chronic-type) was investigated under the three headings of: gangsters, criminal records and broken families. Of 19 patients who are gangsters, 18 cases were acute and the remaining case was chronic. Of 64 patients with criminal records, 51 were acute and 13 were chronic. Of 24 patients who come from broken families, 20 were acute and 4 were chronic. In all of these three items, the rate of acute-type patients was significantly higher than that of chronic-type patients. Based on the results obtained, the medical treatment and the prognosis of the patients, the author refers to preventive measures for stimulant-drug abuse.
