Brain Stent Fails to Prevent Strokes, NIH Stroke Prevention Trial has Immediate Implications for Clinical Practice

Patients at a high risk for a second stroke who received intensive medical treatment had fewer strokes and deaths than patients who received a brain stent in addition to the medical treatment, a large nationwide clinical trial has shown. The investigators published the results in the online first edition of the New England Journal of Medicine [1]. The National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, funded the trial. The medical regimen included daily blood-thinning medications and aggressive control of blood pressure and cholesterol.

New enrollment in the study was stopped in April because early data showed significantly more strokes and deaths occurred among the stented patients at the 30-day mark compared to the group who received the medical management alone.

Rehabilitation After Stroke: They do it with Mirrors

Recent research by Michielsen and colleagues has demonstrated that “mirror therapy”, which can be given at home, results in significant, albeit modest, improvement in arm, wrist and hand movement abilities of stroke patients [1]. Mirror therapy is where the arm with impaired movement is placed behind a mirror and the unimpaired arm is reflected in the mirror, giving the appearance to the patient that when the unimpaired arm is moved, the impaired arm is also moving.

Neural Stem Cell Therapy for Ischemic Stroke Patients

The single largest cause of adult disability in the developed world is ischemic stroke, in which blood flow in or to the brain is blocked. It precipitates immense amounts of social and financial costs. Currently, therapies for stroke focus on prevention or acute phase treatments that arrest the stroke while it is happening. But many patients are not fortunate enough to get acute phase treatment and suffer neurological damage that leads to functional and cognitive impairment. Until now, there have been almost no options for such patients. But last February, a company called ReNeuron received approval to begin a clinical trial of neural stem cell therapy for disabled stroke patients [1]. Two patients have been treated thus far and the therapy appears to be safe.

Rehabilitation Study Looks at Getting Stroke Patients Back on Their Feet

In the largest stroke rehabilitation study ever conducted in the United States, stroke patients who had physical therapy at home improved their ability to walk just as well as those who were treated in a training program that requires the use of a body-weight supported treadmill device followed by walking practice.

The study, funded by the National Institutes of Health, also found that patients continued to improve up to one year after stroke, defying conventional wisdom that recovery occurs early and tops out at six months. In fact, even patients who started rehabilitation as late as six months after stroke were able to improve their walking.

The results of the study were announced last month at the American Stroke Association’s International Stroke Conference 2011 in Los Angeles. NIH’s National Institute of Neurological Disorders and Stroke (NINDS) provided primary funding for the study.

Sleep Apnea Tied to Increased Risk of Stroke

Obstructive sleep apnea is associated with an increased risk of stroke in middle-aged and older adults, especially men, according to new results from a landmark study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. Overall, sleep apnea more than doubles the risk of stroke in men. Obstructive sleep apnea is a common disorder in which the upper airway is intermittently narrowed or blocked, disrupting sleep and breathing during sleep.
