This document discusses pathological gambling as an impulse control disorder that causes disruptions in personal, family, social, and work life. It can be viewed as an addiction, as people develop tolerance requiring them to spend more time and money gambling to achieve the same excitement. Withdrawal symptoms may occur when stopping gambling. The clinical course of gambling typically involves three phases - winning, losing, and desperation - as debts and legal problems grow due to attempts to win back losses or gain more money to gamble. Various treatment options exist for gambling addiction.
