Abstract:
Late-life depression (LLD) is often caused or exacerbated by cerebrovascular pathology; whereas exercise has well-documented effects on improving cerebrovascular function, including cerebral blood flow (CBF). We propose that exercise may alleviate depressive symptoms and reduce LLD by enhancing CBF. However, this mechanistic pathway has not been directly tested. Future research should evaluate this model to develop targeted interventions for LLD. Summary: Exercise-induced changes in cerebral blood flow may mediate the association between exercise and depression in older adults.

Brain Imaging
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
