Which statement best describes when EEGs are ordered?

• A. Wanting to rule out seizure disorder or organic brain dysfunction as the cause of psychiatric symptoms
• B. A patient experiences a sudden, unexplained change in mental status
• C. EEGs are never ordered in psychiatry
• D. EEGs are ordered routinely for all psychiatric evaluations

Answer: (A)

EEGs in psychiatry are used to check if a neurological issue, especially seizures or other brain dysfunction, could be the cause of psychiatric symptoms. This is why the best statement describes ordering an EEG when there is concern that a seizure disorder or organic brain dysfunction might be contributing to the presenting symptoms. It’s not a routine test for every patient, and it’s not never ordered; it’s specifically used when there’s clinical reason to suspect a neurological cause behind psychiatric manifestations. In cases of a sudden unexplained change in mental status, an EEG may be part of the workup, but the core idea is that EEGs help rule out seizures or organic brain disease as the underlying cause.
