A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Blocking calcium channels in brain capillaries may enhance blood flow and alleviate early-stage Alzheimer's damage, new study suggests. Study: Inhibiting Ca 2+ channels in Alzheimer’s disease model ...
