title: Transcranial Doppler sonographic identification of a subgroup of patients with normal pressure hydrocephalus with coexistent vascular disease and treatment failure.
abstract: We report on transcranial Doppler sonography with carbogen reactivity testing of flow velocity as applied to patients with normal pressure hydrocephalus. A subgroup can be differentiated that shows coexistent cerebrovascular disease. The surgical prognosis in these patients is bad. A flow chart demonstrating the proposed clinical examination is presented.
