While addiction commonly involves a substance (substance abuse disorders, eg, alcohol use disorder, cocaine use disorder, methamphetamine use disorder, opioid use disorder), it can also involve an activity, and thus there is overlap with and the differential would include impulse disorders and obsessive-compulsive disorder (OCD), in which there is loss of voluntary control over specific activities. Substance abuse includes increasing amounts of time spent in obtaining, taking, and recovering from the substance at the expense of time otherwise spent in other activities; unsuccessful efforts to decrease the substance use; and continuation despite recognizing its harmful effects. For many substances of abuse, genetic susceptibility is likely.
Studies support an increased association of addiction disorders among patients with comorbid schizophrenia, bipolar disorder, depression, and antisocial personality disorder. The course is variable and dependent on many factors including the particular substance of abuse, but patients with comorbid psychiatric diagnoses often have more prolonged courses, perhaps due to inadequate diagnosis and treatment of the comorbidity.
