Is your passion for gambling, exercising, or watching online videos a fun hobby or a sign of something more serious? It might surprise you, but addiction is a complex condition that comes in many forms and can happen to anyone. Generally speaking, addiction is an inability to stop using a substance (from tobacco to illegal drugs) or engaging in a behavior (from shopping to sex) despite negative consequences. Why is this? The reward center in the brain releases dopamine in response to a pleasurable experience or hyperarousal. The more times people experience the behavior, the more dopamine is released and the more driven they are to return to the behavior. If you find yourself shifting your priorities, increasingly isolated or feeling irritable when not engaged in a behavior, it may be time to get help in breaking the pattern.
