Kleptomania is an impulse control disorder characterized by recurrent failure to resist impulses to steal items even though they are not needed for personal use or their monetary value. It affects about 0.3-0.6% of the population and is more common in females. Biological factors like low serotonin levels and psychological factors like operant conditioning may contribute to its development. Treatment involves cognitive behavioral therapy and medication like SSRIs to increase serotonin levels and reduce urges to steal.
