  • Title: Akinetic mutism responsive to bromocriptine following subdural hematoma evacuation in a patient with hydrocephalus.
    Author: Kim MS, Rhee JJ, Lee SJ, Kwon SJ, Lee CH.
    Journal: Neurol Med Chir (Tokyo); 2007 Sep; 47(9):419-23. PubMed ID: 17895616.
    Abstract:
    An 11-year-old girl with obstructive hydrocephalus developed akinetic mutism after treatment for hydrocephalus due to aqueductal stenosis by ventriculoperitoneal (VP) shunting. Bilateral chronic subdural hematomas developed about 2 months after insertion of the VP shunt and were evacuated. Postoperatively, the patient developed akinetic mutism, but her condition improved after administration of bromocriptine. Absence of abnormalities on dopamine transporter single photon emission computed tomography, lack of clinical response to levodopa treatment, and normal homovanillic acid concentration in the cerebrospinal fluid all indicated normal dopamine production. Pressure on the periventricular monoamine projections in the thalamus and hypothalamus without major dopamine deprivation in the striatum may have been the most important factors in the development of akinetic mutism in this patient.
