A case of catatonia due to posterior reversible encephalopathy syndrome treated successfully with antihypertensives and adjunctive olanzapine.

Catatonia is a distinct neuropsychiatric syndrome with prominent motor manifestations. Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic syndrome usually precipitated by malignant hypertension. Given the overlapping neuropathology in both syndromes, we present a case of catatonia precipitated by PRES, with full resolution of the former after successful treatment of the latter.
