Evaluation of rapidly progressive dementia (RPD) is usually challenging. In most cases, patients progress to dementia in weeks to months, and the differential diagnosis is broad. In this case, a woman in her 60s presented with a 1-month history of episodic vertigo, cognitive decline, ataxia and myoclonus. Cerebrospinal fluid total tau was markedly elevated, which was helpful in establishing the diagnosis and discussing prognosis/end-of-life measures with the patient’s family. This case summarises a stepwise diagnostic approach for patients with RPD and highlights recent literature on biomarkers of Creutzfeldt-Jakob disease and autoimmune encephalitis.
