Which of the following is NOT categorized as a psychiatric condition?

The distinction of substance abuse as not being categorized as a psychiatric condition lies in its classification within the realm of mental health disorders. Substance abuse is typically regarded as a behavior or condition primarily associated with the misuse of drugs or alcohol rather than a distinct psychiatric disorder. While it does overlap with mental health issues and can co-occur with psychiatric conditions, it is primarily focused on the physiological and psychological consequences of substance use, leading to dependency or addiction. This is why it is often classified separately from the more traditional psychiatric conditions such as Alzheimer’s, depression, and schizophrenia, which are recognized as mental illnesses that primarily affect mood, cognitive function, and perception.

Alzheimer's disease, depression, and schizophrenia are all classified as psychiatric disorders because they involve changes in thought processes, emotional regulation, and behaviors that are not solely attributable to substance use. These conditions have specific diagnostic criteria and often require different approaches for treatment and management than substance-related disorders.
