Cerebral Hemodynamic Changes in Older Adults With Cognitive Complaints According to the Presence of Peripheral Artery Disease

AGING MEDICINE, EarlyView.
Among 132 older adults, 13 had peripheral artery disease (PAD), identified using the ankle–brachial index. Over approximately 13 months, PAD was associated with increasing middle cerebral artery mean flow velocity, with a significant difference in left‐sided velocity change between groups.
