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.

Research shows brain cells regulate blood vessel development

Zhen Huang freely admits he was not interested in blood vessels four years ago when he was studying brain development in a fetal mouse. Instead, he wanted to see how changing a particular gene in brain cells called glia would affect the growth of neurons.

Study identifies how astrocytes regulate a neurotransmitter involved in sleep

Neuroscience researchers from Tufts University have found that our star-shaped brain cells, called astrocytes, may be responsible for the rapid improvement in mood in depressed patients after acute sleep deprivation. This in vivo study, published in the current issue of Translational Psychiatry, identified how astrocytes regulate a neurotransmitter involved in sleep.

Roundup: Ariz. Gov. proposing hospital tax for Medicaid expansion as Nev. ponders options; Vt. hospitals form ACO

Ariz. Gov. Jan Brewer, who has become something of a conservative icon for her aggressive opposition to Mr. Obama's policies, surprised many Legislature watchers at her State of the State address last week by saying she wanted to expand the state's Medicaid program to include anyone who makes up to 133 percent of the federal poverty level, or $14,856 for an individual.
