Optic nerve may help predict stroke patient death risk

Using optic ultrasound to measure the sheath of a nerve that connects the eye and brain can help identify acute stroke patients most at risk of dying within days or months, according to research presented at the American Stroke Association’s International Stroke Conference 2015.

The new study aimed to quickly […]

Many mild stroke patients considered “too good to treat” may actually benefit from tPA

Stroke patients with mild symptoms might be eligible to receive the clot-busting drug tissue plasminogen activator, but often don’t receive the therapy because they are deemed “too good to treat.”

However, many of these patients don’t fare well after stroke, according to research presented at the American Stroke Association’s International […]

Clot-removing devices provide better outcomes for stroke survivors

Strokes caused by large blood clots in the brain are less likely to result in disability or death if the blockage is removed in the crucial early hours, according to reaffirming new research widely celebrated Wednesday.

Doctors quickly lauded the findings as instantly changing the way certain stroke sufferers are […]

Low vitamin D predicts more severe strokes, poor health post-stroke

Stroke patients with low vitamin D levels were found to be more likely than those with normal vitamin D levels to suffer severe strokes and have poor health months after stroke, according to research presented at the American Stroke Association’s International Stroke Conference 2015.

Low vitamin D has been associated […]

Stroke survivors more likely to make dangerous driving errors

Drivers who have had recent strokes are more likely than drivers who have not had strokes to make errors during complex driving tasks, according to two small Canadian studies presented at the American Stroke Association’s International Stroke Conference 2015.

“Current guidelines recommend that patients should refrain from driving for a […]

Natural brain-repair substance may improve stroke outcome

Supplementing a natural substance that protects nerve cells and encourages new blood vessel formation may aid in new neural growth after stroke when started a week later, according to a mouse study presented at the American Stroke Association’s International Stroke Conference 2015.

Currently, the only FDA-approved drug, tPA, which dissolves […]

Spleen may be key target for successful cell therapy after stroke

The spleen — not the brain — may be the key target in successful cell therapy after a stroke, according to a study in mice presented at the American Stroke Association’s International Stroke Conference 2015.

After a stroke, the spleen seems to contribute to ongoing inflammation and brain damage.

Researchers compared […]

Stem cell injections may improve cognitive function after stroke

Stem cell injections into the brain may improve some cognitive functions in people who haven’t recovered months or years after a clot-caused stroke, according to a study presented at the American Stroke Association’s International Stroke Conference 2015.

In a preliminary study, 18 patients who had sustained moderate or severe ischemic […]

Limiting social isolation improves stroke outcomes in aged mice

Housing aged mice in pairs enhances their recovery after stroke, according to a study presented at the American Stroke Association’s International Stroke Conference 2015.

Social isolation slows functional recovery and worsens cell damage after stroke in young animals, primarily by increasing the body’s inflammatory response. Changes occur in the inflammatory […]

Leakier guts may be why elderly have worse stroke outcomes

Leakier guts may be why older people are more likely to die or have a poor recovery after clot-caused strokes, according to a study in mice presented at the American Stroke Association’s International Stroke Conference 2015.

Researchers found that molecules and bacteria cross the intestinal walls in both aged mice […]
