What condition may co-occur with psychotic disorders?

The co-occurrence of substance use disorder with psychotic disorders is well-established in mental health research. Many individuals with psychotic disorders may turn to substances as a form of self-medication or may develop a substance use disorder due to drug-induced psychosis. Substances such as alcohol, stimulants, and hallucinogens can exacerbate or mimic psychotic symptoms, making the disorders challenging to differentiate and treat. Understanding this relationship is crucial for healthcare providers as it underscores the importance of assessing and addressing substance use when treating patients with psychotic disorders.

On the other hand, while obsessive-compulsive disorder may co-occur with many mental health conditions, it does not have the same strong, direct association with psychotic disorders as substance use disorders. Similarly, avoidant personality disorder and allergic reactions do not typically show a notable connection with the onset or exacerbation of psychosis, making them less relevant in the context of co-occurring conditions.
