Amotivational syndrome is a psychiatric disorder characterized by a lack of motivation and reduced cognitive functioning. It was first described in the 1960s among long-term cannabis users. Chronic use of psychoactive substances like cannabis, cocaine, and medications like SSRIs can potentially cause changes in the brain's frontal lobe and serotonin/dopamine activity linked to symptoms of amotivational syndrome. These include reduced energy, passivity, introversion, apathy, poor concentration, and decreased desire for social interaction and work. Treatment involves medication to address neurological imbalances, counseling, lifestyle changes, and abstaining from psychoactive substance use. With treatment and abstinence, symptoms are potentially reversible within months.
