Insomnia may significantly increase stroke risk
Insomnia may significantly increase your risk of stroke and subsequent stroke hospitalizations. The risk was highest -- up to eight times -- among insomniacs 18-34 years old in a recent study. The risk also seems to be far greater when insomnia occurs as a young adult compared to those who are older, said researchers.

Bone marrow stem cells show promise in stroke treatment
Stem cells culled from bone marrow may prove beneficial in stroke recovery, scientists have learned. The researchers identified 46 studies that examined the use of mesenchymal stromal cells -- a type of multipotent adult stem cells mostly processed from bone marrow -- in animal models of stroke. They found MSCs to be significantly better than control therapy in 44 of the studies.

Severe sleep apnea linked to increased risk of stroke, cancer, death
Moderate to severe obstructive sleep apnea is independently associated with an increased risk of stroke, cancer and death. Results of the 20-year follow-up study show that people with moderate to severe obstructive sleep apnea were four times more likely to die (hazard ratio = 4.2), nearly four times more likely to have a stroke (HR = 3.7), three times more likely to die from cancer (HR = 3.4), and 2.5 times more likely to develop cancer. Results were adjusted for potential confounding factors such as body mass index, smoking status, total cholesterol and blood pressure.

Airport security-style technology could help doctors decide on stroke treatment
A new computer program could help doctors predict which patients might suffer potentially fatal side-effects from a key stroke treatment. The program assesses brain scans using pattern recognition software similar to that used in airport security and passport control. Currently, stroke affects over 15 million people each year worldwide. Ischemic strokes are the most common and these occur when small clots interrupt the blood supply to the brain.

Glutamate imaging better than MR spectroscopy in first 3 hours after ischemic stroke
Glutamate imaging reveals ischemic lesions in the first 3 hours after stroke that are not distinguishable in T1-weighted and T2-weighted imaging. The finding has the potential to speed diagnosis -- and, therefore, treatment -- in the critical first hours after a stroke.

Diet higher in protein may be linked to lower risk of stroke
People with diets higher in protein, especially from fish, may be less likely to have a stroke than those with diets lower in protein, according to a meta-analysis. The meta-analysis looked at all of the available research on the relationship between protein in the diet and the risk of stroke. Seven studies with a total of 254,489 participants who were followed for an average of 14 years were included in the analysis.

Blocking key enzyme minimizes stroke injury, research finds
A drug that blocks the action of the enzyme Cdk5 could substantially reduce brain damage if administered shortly after a stroke, research suggests. The development of a Cdk5 inhibitor as an acute neuroprotective therapy has the potential to reduce stroke injury, researchers report.

High stress, hostility, depression linked with increased stroke risk
Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of stroke or transient ischemic attack (TIA) in middle-age and older adults, according to new research. A TIA is a stroke caused by a temporary blockage of blood flow to the brain.

Stem cells show promise for stroke in pilot study
A stroke therapy using stem cells extracted from patients’ bone marrow has shown promising results in the first trial of its kind in humans. The therapy uses a type of cell called CD34+ cells, a set of stem cells in the bone marrow that give rise to blood cells and blood vessel lining cells. Rather than developing into brain cells themselves, the cells are thought to release chemicals that trigger the growth of new brain tissue and new blood vessels in the area damaged by stroke.

Neck manipulation may be associated with stroke
Manipulating the neck has been associated with cervical dissection, a type of arterial tear that can lead to stroke. Although a direct cause-and-effect link has not been established between neck manipulation and the risk of stroke, healthcare providers should inform patients of the association before they undergo neck manipulation.

Hospitalizations, deaths from heart disease, stroke drop in last decade
U.S. hospitalizations and deaths from heart disease and stroke dropped significantly in the last decade, according to new research. Furthermore, risks of dying for people who went to the hospital within a year decreased about 21 percent for unstable angina, 23 percent for heart attacks and 13 percent for heart failure and stroke.

Statin use during hospitalization for hemorrhagic stroke associated with improved survival
This study was conducted by the same researchers who recently discovered that the use of cholesterol-lowering statins can improve survival in victims of ischemic stroke.

Implications of ipsilateral spatial neglect after stroke explored by stroke researchers
Stroke researchers have confirmed that damage to the right frontal-subcortical network may cause ipsilateral spatial neglect. More patients with ipsilateral neglect had frontal subcortical damage than anticipated -- 83 percent vs the expected 27 percent. A difference was also seen in spatial bias, ie, the type of spatial errors among this group tended to be 'where'(perceptual-attentional) rather than 'aiming' (motor-intentional) errors.

Stroke patients past 90-day danger period remain at high risk for repeat event
People who have had a stroke or transient ischemic attack (TIA or mini-stroke) are at high risk for a second similar event or other serious medical problems for at least five years and need better follow up and strategies to prevent these problems, according to data.

Healthy lifestyle may cut stroke risk in half for women
Women with a healthy diet and lifestyle may be less likely to have a stroke by more than half, according to a study. The study looked at five factors that make up a healthy lifestyle: healthy diet; moderate alcohol consumption; never smoking; physically active; and healthy body mass index (BMI). Compared with women with none of the five healthy factors, women with all five factors had a 54-percent lower risk of stroke.
