title: Central dizziness associated with cerebral blood flow disorders.
abstract: This retrospective study describes the use of transcranial Doppler (TCD) and history for further defining and diagnosing cerebral blood flow (CBF) disorders in patients with central dizziness. Central dizziness was defined as dizziness of nonlabyrinthine, non-peripheral causes. It was believed that at least some of the causes for central dizziness are not unknown but are associated with CBF disorders. Fifty patients who presented with central dizziness were examined and subsequently tested with TCD. In 33 of 50 cases (66%) a diagnosis could be assigned after TCD; whereas, on the basis of both history and TCD a diagnosis was assigned to 38 patients (76%).
