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.

Bats' Navigation Brain Cells Also Encode Social Information

The same neurons that help bats navigate through space may also help them navigate collective social environments, finds a new study published today in the journal Nature.

Direct-to-Consumer Blood Test for Assessing User’s Alzheimer’s Disease Risk

In July, the first direct-to-consumer blood test designed to assess a user’s risk for developing Alzheimer’s disease hit the market. The test, which has not undergone Food and Drug Administration (FDA) review, measures the level of a protein called beta amyloid, a key component of plaques that form in the brains of Alzheimer’s disease patients, disrupting brain function.

Study Links Adenovirus Infection With a Rare Blood Clotting Disorder

Platelets, or thrombocytes, are specialized cellular fragments that form blood clots when we get scrapes and traumatic injuries. Viral infections, autoimmune disease, and other conditions can cause platelet levels to drop throughout the body, termed thrombocytopenia.

Integrating Ultrasound with Genetics to Precisely Modify Neurons in the Brain

Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the brain.
