“…While they found three distinct sub-profiles, delusions were common amongst all individuals with METH-induced psychosis. Additional studies have also reported that METH psychosis is associated with a high prevalence of persecutory delusions, auditory and visual hallucinations, odd speech, and delusions of reference ( 15 , 40 , 60 , 113 , 119 – 122 ).…”

“…Furthermore, METH can induce a chronic psychosis in those with no premorbid psychiatric risk factors ( 54 ), suggesting that METH use can induce persistent physiological changes consistent with psychosis that are independent to genetic and personality predispositions. It is recommended that readers examine many of the comprehensive review articles available for further information on the clinical profiles, correlates, and recovery of METH-induced psychosis ( 55 – 60 ). Overall, METH psychosis can result in a persistent psychotic syndrome that is resistant to spontaneous recovery, and in light of the high use of METH use globally, chronic METH psychosis will undoubtedly continue to be an issue for health-care professionals.…”

“…The current review will describe and critique the literature that has compared the clinical profile of schizophrenia with (i) acute METH psychosis and (ii) chronic METH psychosis, with particular focus on positive, negative and cognitive symptoms. While several reviews have examined the clinical profiles, risk factors, and correlates of METH-psychosis ( 55 , 59 , 60 ) and cognitive deficits associated with METH use ( 102 – 104 ), the aim of this study was to provide a comprehensive overview of research that has directly compared METH psychosis (acute and chronic) with schizophrenia. Furthermore, while ( 55 ) have reviewed the relationship between METH psychosis and schizophrenia, we wished to extend this review by differentiating between acute and persistent forms of METH psychosis.…”

A Comparison of Methamphetamine-Induced Psychosis and Schizophrenia: A Review of Positive, Negative, and Cognitive Symptomatology

Methamphetamine is a potent psychostimulant that can induce psychosis among recreational and chronic users, with some users developing a persistent psychotic syndrome that shows similarities to schizophrenia. This review provides a comprehensive critique of research that has directly compared schizophrenia with acute and chronic METH psychosis, with particular focus on psychiatric and neurocognitive symptomatology. We conclude that while there is considerable overlap in the behavioral and cognitive symptoms between METH psychosis and schizophrenia, there appears to be some evidence that suggests there are divergent aspects to each condition, particularly with acute METH psychosis. Schizophrenia appears to be associated with pronounced thought disorder, negative symptoms more generally and cognitive deficits mediated by the parietal cortex, such as difficulties with selective visual attention, while visual and tactile hallucinations appear to be more prevalent in acute METH-induced psychosis. As such, acute METH psychosis may represent a distinct psychotic disorder to schizophrenia and could be clinically distinguished from a primary psychotic disorder based on the aforementioned behavioral and cognitive sequelae. Preliminary evidence, on the other hand, suggests that chronic METH psychosis may be clinically similar to that of primary psychotic disorders, particularly with respect to positive and cognitive symptomatology, although negative symptoms appear to be more pronounced in schizophrenia. Limitations of the literature and avenues for future research are also discussed.
