Addiction and the Role of Dopamine

Dopamine is a neurotransmitter that plays a central role in pleasure, reward, and motivation. It is released in response to reinforcing substances and behaviors, such as drugs, gambling, and even social media. Individuals with addictive tendencies may have a genetic predisposition or vulnerability to addiction. Addiction is characterized by compulsive use despite harm to oneself or others. Dopamine deficiency has been linked to depression and other mental health disorders. Treatment options include biological interventions such as medication, psychological interventions like mindfulness practices, and social interventions such as support groups like 12-step programs.
