title: Secondary normal pressure hydrocephalus in a patient with isolated frontal dilatation--an insight into pathophysiology?
abstract: Current theories of the pathophysiology of normal pressure hydrocephalus suggest the classical symptoms are a consequence of disruption of normal frontal function. We present the case of a 70-year-old patient with an isolated, frontal dilatation of his lateral ventricles in the presence of a complete triad as supportive of these theories.
