Case Report

A 27-year-old man with a history of substance abuse developed a new-onset compulsive gambling pattern within weeks of starting aripiprazole.

A 48-year-old woman with schizoaffective disorder taking clozapine developed acute pulmonary embolism despite negative D-dimer results.

The authors present the case of a 10-year-old boy with autism who presented to the ED with hyponatremia-related seizures due to compulsive water drinking.

The authors describe a case of intentional overdose with diphenhydramine and extended-release dextromethorphan-guaifenesin that initially presented with anticholinergic toxicity and later evolved into serotonin toxicity.

This case reinforces the importance of monitoring for acute neurologic symptoms in patients treated with high-dose selective serotonin reuptake inhibitors.

A 44-year-old woman was initially referred for presumed domperidone-induced extrapyramidal symptoms, but further workup uncovered a complex interplay of hyponatremia, demyelination, and neuroleptic hypersensitivity.
