C.B., a 20-year-old woman, was recently diagnosed with major depressive disorder, single episode. Since the age of 8 years, she has also experienced complex partial seizures. Her seizures have been difficult to control in the past (at least six seizures per month), but her condition has improved recently (none for 8 months) on a combination of carbamazepine and gabapentin. Are there any special considerations with regard to antidepressant selection in C.B.?
