Long‐term outcomes in methamphetamine psychosis patients after first hospitalisation

Abstract

Individuals with MAP are likely to have poor outcomes, in terms of premature death, several relapses of psychotic symptoms, chronic psychotic manifestation, and very rates of alcohol use disorder and suicidality. Therefore, those individuals with MAP require long-term monitoring and psychiatric care.

Update on methamphetamine: an old problem that we have recently encountered

“…A follow-up study in Thailand revealed that onequarter of patients with methamphetamine psychosis had been given the diagnosis of schizophrenia within the 5 years following their first hospitalization (48). Close monitoring for the development of chronic or recurrent psychosis among individuals with transient symptoms, possible pharmacological management of acute symptoms, and behavioral treatment and psychoeducation addressing methamphetamine use and its association with psychosis are needed.…”

Amfetaminutløst psykose eller schizofreni?

“…Noen store og solide studier viser at en vesentlig andel av de pasientene som opprinnelig fikk diagnosen amfetaminutløst psykose, senere får diagnosen schizofreni. I en studie fra Asia fulgte man pasienter 6 -7 år etter første innleggelse for amfetaminutløst psykose og konkluderte med at 23 % av dem uten pågående amfetaminbruk fylte diagnosekriteriene for schizofreni (5). I en registerstudie fra Finland var det liknende funn -det var en åtteårs kumulativ risiko på 30 % for overgang fra amfetaminutløst psykose til schizofreni.…”

Stimulant use disorders and psychosis: prevalence, correlates and impacts

“…Many young people with psychosis abuse stimulant drugs (Hides et al, 2006;Sara et al, 2013) however most of these young people also abuse cannabis (Degenhardt et al, 2010b), making it difficult to separate the effects of these two drugs. In a large Thai sample, more than half of first admissions with specific diagnoses of methamphetamine psychosis went on to have further episodes of psychosis (Kittirattanapaiboon et al, 2010). …”

“…South East Asian countries have high rates of methamphetamine use and researchers from these countries have contributed many of the studies examining the familial, genetic and pharmacological characteristics of methamphetamine-related psychoses (Bousman et al, 2009). Most of these studies use a diagnostic construct of "Methamphetamine Psychosis", which is seen as including both acute and transient psychotic states (Kittirattanapaiboon et al, 2010) and psychosis which persists or recurs despite abstinence from stimulants (Sato et al, 1992;Suzuki et al, 2006;Yamamoto et al, 2007;Yui et al, 2000a).…”

“…Stimulants can precipitate brief syndromes of drug-induced psychosis (Bramness et al, 2012;Crebbin et al, 2009), sometimes diagnosed as "methamphetamine psychosis" (Kittirattanapaiboon et al, 2010;Yui et al, 2000b).…”
