Final answer:
Obsessive-compulsive disorder should not be considered in the differential diagnosis for intermittent explosive disorder because it typically involves repetitive thoughts and behaviors, not aggressive outbursts.
Step-by-step explanation:
When considering the differential diagnosis for intermittent explosive disorder (IED), it is important to consider conditions that might present with similar symptoms. The diagnosis of IED typically involves ruling out other medical and psychological conditions that could explain the episodes of aggressive outbursts. Among the listed options, 'D. Obsessive-compulsive disorder (OCD)' should not be considered in the differential diagnosis for IED. While temporal lobe epilepsy may include episodes of aggression, and substance intoxication, delirium, and dementia might also present with similar symptoms, OCD is characterized by repetitive thoughts and behaviors and does not typically include aggressive outbursts as a primary symptom. Therefore, OCD is not commonly considered when diagnosing IED.
