Could repeated squeezes to the arms, legs protect the brain?

Ischemic preconditioning may help to prevent stroke, a new study reports. Restricting blood flow by wearing inflatable blood pressure cuffs on the arms and legs allows for more controlled blood flow to the brain.

Brain Blood Flow Issues Linked to Mild Cognitive Impairment

Older adults with mild cognitive impairment (MCI) face higher cerebrovascular impedance, or resistance in brain blood flow, according to a new study. Researchers found this increased resistance leads to hypoperfusion, or reduced blood flow in the brain, which may contribute to cognitive difficulties in aging adults.

This computation model reveals that blocking CaV1.2 or CaV3.3 dilates cerebral arteries and increases blood flow, whereas blocking CaV3.2 constricts arteries and decreases cerebral blood flow.

Obesity Linked to Reduced Blood Flow to the Brain

Obesity has been linked to severely restricted blood flow in the brain. Reduced blood flow in the brain, or cerebral hypoperfusion, can be an early indicator of vascular dementia and Alzheimer's disease.
