There are many similarities between psychiatric disorders and substance abuse disorders. Psychiatric symptoms can be caused, simulated, or masked by drug use disorders (SUDs). Additionally, psychiatric and SUD disorders can independently co-exist, and psychiatric behaviors can mimicSUD disorders. Research shows that the relationship is complex, suggesting many possible points of overlap between addiction and psychiatric disorders.Therefore, it is crucial to understand how psychiatric and substance use disorder symptoms interact.

Give examples of at least five psychiatric disorders that can interfere with diagnosis and mislabeled substance use disorders. In each case, be specific and identify the psychiatric condition and symptom(s), the substance and its influence (cause), the overlap (mimic), and the interrelationship.
