Psychological Terms — Amphetamine-Related Disorders
Amphetamine-related disorders comprise a class of substance-related and addictive disorders arising from excessive use or dependence on amphetamine and structurally similar stimulants, including dextroamphetamine and methamphetamine. These conditions include misuse, physiological dependence, tolerance, withdrawal, and a variety of behavioral and psychiatric disturbances induced by the drug.
Clinically, affected individuals may display persistent cravings, escalating dosage patterns, and impaired functioning across social, academic, and occupational domains. Psychiatric complications can include severe anxiety, agitation, paranoid ideation, and, in some cases, amphetamine-induced psychosis. Physiological complications may include cardiovascular strain, malnutrition, insomnia, and neurotoxicity.
Diagnostic systems classify amphetamine-related disorders under stimulant-type substance disorders and emphasize differential diagnosis from other forms of stimulant use, such as cocaine. Because amphetamine’s reinforcing properties and long duration of action increase its dependency potential, structured intervention—including behavioral therapies and medical support—is often required.
