Recreational and therapeutic use of psychostimulants such as amphetamine, cocaine, methamphetamine, MDMA, methylphenidate, caffeine, and nicotine can cause brain dysfunction and neurotoxic effects. This review of research from 2018 to 2023 examines evidence from both experimental models and humans, highlighting that central toxicity from these substances poses serious health risks, especially as their use rises among young people and adults. Understanding the factors and mechanisms behind these noxious brain effects is crucial for grasping the acute and lasting harm that may occur in users.

A standardized extract of Withania somnifera (ashwagandha), when given acutely alongside MDMA (ecstasy), protects mice from the drug's harmful effects on the brain, body temperature, and memory. MDMA alone caused degeneration of dopamine-producing neurons, inflammation (gliosis), a rise in body temperature, and impaired performance on a novel object recognition task. These effects were not prevented by pretreating mice with the extract for three days before MDMA. However, when the extract was given together with MDMA, it counteracted the loss of dopamine neurons in the substantia nigra, reduced gliosis in the striatum, normalized body temperature, and restored memory performance to levels similar to those of saline-treated controls.

correction
This is a corrigendum (correction notice) for a previously published research article. It does not provide new findings or data. The original study investigated how Withania somnifera (ashwagandha) affected MDMA-induced hyperthermia, cognitive impairment, neurotoxicity, and neuroinflammation in mice.
