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.

Blood Flow Waves Wash Across Brain Surface

Researchers visualized the full network of blood vessels in awake mice, discovering rhythmic expansions and contractions that create blood flow waves across the brain's surface. This study reveals new insights into brain blood supply, though the function of these waves remains unclear.

Brain Blood Flow Syncs with Visual Stimuli

Researchers pioneered a new method to monitor blood vessel dynamics in the mouse brain, revealing that visual stimuli can synchronize vasomotion, potentially improving brain function. By exposing mice to a specific pattern of horizontally moving stripes, the team observed that vasomotion matched the stimulus pattern's speed and spread throughout the brain.

Older Women With Type 2 Diabetes Have Different Patterns of Blood Use in Their Brains

Older women with type 2 diabetes do not use as much oxygenated blood in their brains as those who do not have the disease. Findings demonstrate alterations in neural blood use are a primary reason for deficits in motor function experienced by those with diabetes.
