Mean cerebral transit time in demented and normal elderly persons.
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.
