Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Looking for a natural way to lower blood pressure? Whole grains might be the answer

A new meta-analysis of prospective cohort studies found that higher whole grain intake is linked to a significantly lower risk of developing hypertension, with a 26% risk reduction observed between highest and lowest intake groups. In contrast, refined grain consumption showed no clear association with hypertension risk.

Brain cells can burn fat to fuel activity

While glucose, or sugar, is a well-known fuel for the brain, Weill Cornell Medicine researchers have demonstrated that electrical activity in synapses—the junctions between neurons where communication occurs—can lead to the use of lipid or fat droplets as an energy source.
