Data on Applied Physiology Published by a Researcher at National Institute of Advanced Industrial Science and Technology (NIAIST) (Patients with Amnestic Mild Cognitive Impairment Have Higher Cerebrovascular Impedance Than Cognitively Normal...).

A new report from researchers at the National Institute of Advanced Industrial Science and Technology (NIAIST) in Japan suggests that patients with amnestic mild cognitive impairment (aMCI) have higher cerebrovascular impedance than cognitively normal older adults. The study found that higher cerebrovascular impedance may contribute to brain hypoperfusion, which is associated with cognitive impairment. The researchers measured carotid artery pressure and middle cerebral arterial blood velocity in 58 patients with aMCI and 25 cognitively normal subjects. The findings suggest that increased cerebrovascular impedance is associated with brain hypoperfusion in patients with aMCI. [Extracted from the article]
