title: Mean cerebral transit time in demented and normal elderly persons.
abstract: The mean cerebral transit time (MCTT) was measured in 31 elderly subjects, approximately half of whom suffered from chronic dementing illness. The results indicated a significant correlation between the MCTT and arm-to-head circulation time. Both times increased significantly with age. There was no difference in MCTT between demented and non-demented patients.
