title: Akinetic mutism and parkinsonism associated with obstructive hydrocephalus.
abstract: We report the case of a patient with idiopathic aqueductal stenosis and hydrocephalus who had several episodes of akinetic mutism, each preceded by shunt malfunction, that resolved with shunt revision. She also developed a parkinson's syndrome resistant to shunt revision but responsive to antiparkinsonian medications. The parkinson's syndrome and the episodes of akinetic mutism may be related to a reduction of dopaminergic input to the striatum and to the cingulate and frontal cortex brought about or worsened by ventricular dilatation.
