image of Neurobehavioral Disorders and Cognitive Impairment in Methcathinone Exposure: A Systematic Review of Literature

Abstract

Background

Methcathinone, a synthetic cathinone derivative similar to amphetamine, has transitioned from a 1920s ephedrine precursor and Soviet-era antidepressant to a recreationally used substance since the 1970s-1980s, raising public health concerns due to its addiction potential and neurotoxicity-related health risks.

Objective

This review comprehensively analyzes methcathinone's impact on adult offspring, synthesizing recent advancements and critiquing literature to pinpoint key findings, challenges, and future research directions.

Methods

The systematic review adhered to PRISMA guidelines and encompassed case series, prospective and retrospective studies, as well as short communications published in English. An electronic search was conducted on PubMed, Elsevier, and CNKI. The focus was on methcathinone and its neuropsychological disorders and physical health complications, specifically in adult offspring.

Results

A total of 8 studies met the inclusion criteria, resulting in a dataset of methcathinone on neurobehavioral and cognitive functions. These studies mainly found that prenatal methcathinone exposure in rats led to delayed physical development and induced anxiety-like behavior in offspring, with changes observed in neurobehavioral tests and the concentration of serotonin and dopamine. Furthermore, neurochemical effects were identified, showing dose- and time-dependent increases in extracellular dopamine and serotonin concentrations, and neurotoxic potential towards brain dopamine neurons.

Conclusion

This study concludes that methcathinone poses severe risks, including neurotoxicity for users and developmental harm for offspring, necessitating ongoing research to comprehend associated risks and inform public health interventions.
