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.

Risks associated with diabetes drug rosiglitazone may be higher than those with pioglitazone

Major discovery in the control of bad cholesterol

A study performed by the team of Dr. Nabil G. Seidah, Director of the Biochemical Neuroendocrinology Research Unit at the IRCM, shows for the very first time that the degradation by PCSK9 of the LDLR receptor, which is responsible for removing the bad cholesterol (LDL-cholesterol) from the bloodstream, may be inhibited by a third protein, annexin A2.

Trial of Gore-tex-type material to stop strokes

A study is under way at Rush University Medical Center using a small, soft-patch device made of a Gore-tex-type material - often used to make durable outerwear - to close a common hole found in the heart called a patent foramen ovale (PFO) in order to prevent recurrent strokes and transient ischemic attacks (TIAs) in adults.
