Medical researchers are investigating whether L-Dopa (commonly used to treat Parkinson’s disease) could help in this new context. There is existing evidence to show that certain nerve pathways in the brain are important in learning movement skills. The drug works by enhancing the activity of these pathways and if taken at the same time as conventional physiotherapy, could increase the effect of current treatment.

The longer a person has had a "poorer" manager, the higher his or her risk of for example suffering a heart attack within a ten-year period, according to new research.

This suggests that increasing the levels of omega-3 fatty acids in carotid artery plaques could either prevent strokes or improve the safety of treatment.

Further risk factors for stroke among patients with migraine are being a woman, being young, being a smoker and using estrogen-containing contraceptives.

A cup of Joe in the morning can wake us, but overloading on caffeine causes the stimulant to work against us.

The timing of the delivery of 100 percent oxygen -- either by mask or in a hyperbaric chamber -- is critical to achieving the benefit, however. Tue, 20 Oct 2009 08:00:00 EDT http://www.sciencedaily.com/releases/2009/10/091019172333.htm http://www.sciencedaily.com/releases/2009/10/091019172101.htm People with high levels of a protein called C-reactive protein, a marker for inflammation in the blood, may be at higher risk for heart attack and death but not stroke, according to a new study.

This result adds to mounting evidence that AMD and cardiovascular disease may share some risk factors--smoking, high blood pressure, inflammatory indicators such as C-reactive protein, genetic variants such as complement factor H--and disease mechanisms.

The study, which was started in 1990 and involved all men and women over the age of 55 living in a suburb of Rotterdam, found no difference in the risk of developing heart failure between those who did eat fish and those who didn't.

When the shingles infection involves the skin around the eye and the eye itself, the risk of stroke may increase more than four-fold. Shingles is a painful skin rash caused by the same virus that causes chickenpox.

Because arterial stiffness often precedes cardiovascular disease, the results suggest that this could become a quick measure of a person's risk for heart attack or stroke.

Most studies rely on diagnostic codes for billing data to assess stroke rates, but this study also considered records of head imaging -- which revealed additional strokes. Researchers say stroke in children is still rare and parents need not be alarmed.

The psychosocial therapy focused on depression education, problem-solving and increasing pleasant experiences. Depression is common after stroke and can impede recovery.

Scientists have explained the mechanism of this clinical paradox for the first time on an animal model. Mice with a greater tendency to form blood clots have larger plaques in their vessels, but they are more stable. Thus, there is less risk that these plaques will rupture and obstruct circulation.
