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.

The authors present a combined cohort of 4 patients with baseline neurocognitive disorders who developed catatonia shortly before death.

ECT can be lifesaving for critically ill individuals with severe psychiatric and neuropsychiatric conditions; however, cardiac monitoring is essential.

The authors report a case of Guillain-Barre syndrome with an atypical presentation, which was initially misdiagnosed due to the patient’s history of schizophrenia treated with lurasidone.
