Delirium in the Pediatric Population: A 17-Year-Old Girl With Baclofen Withdrawal-Induced Psychosis

We report a case of new onset psychosis in a teenager that was initially thought to be caused by a primary psychiatric disorder but was later discovered to be secondary to withdrawal from baclofen therapy. Although withdrawal from oral baclofen has been known to cause delirium in adults and in patients with intrathecal pump malfunction, this report shows that oral baclofen withdrawal can also manifest as psychosis in the pediatric population. It is important for emergency care providers to recognize symptoms of delirium from sources such as medication withdrawal, especially in a pediatric patient, because the treatment differs from that of psychiatric disorders.
