Abstract
Bipolar disorder I (BDI) is a psychiatric disorder characterized by the occurrence of at least one manic episode. Within the scope of neurological disorders, epilepsy and psychogenic nonepileptic seizures (PNES) share clinical features and can be differentiated using electroencephalogram (EEG). Substance use disorder is a condition defined by impaired control, risky use, social impairment, and addictive behaviors. We present the case of a 20-year-old pregnant woman with BDI associated with a history of epilepsy, PNES, and polyvalent substance use. The patient presented to the emergency department via the Baker Act involuntary hold multiple times throughout her pregnancy. Recognizing that the welfare of the mother and child was at risk, the court ordered a two-month commitment of inpatient psychiatric treatment at 30 weeks' gestation to ensure safe delivery. Comprehensive inpatient treatment, including risperidone, levetiracetam, lacosamide, haloperidol, diphenhydramine, lorazepam, and later clozapine, and a discharge plan for both the mother and the child are described in detail. Our goal is to contribute to the growing body of knowledge on the management of complex pregnant patients with psychiatric conditions in order to optimize outcomes for maternal and fetal health.
