Stroke

Stroke hospitalizations rising among younger US adults.Risk factor are obesity, high blood pressure and Diabetes. From 2003-2004 to 2011-2012, acute ischemic stroke hospitalization rates increased for all races and ethnicities and for men and women in the 18 to 34, 35 to 44 and 45 to 54 years old age groups except for non-Hispanic blacks and other race groups for ages 18 to 34 years. For adults between 55 and 64 years old, only Hispanics had a significant increase in acute ischemic stroke hospitalization rates.

Recovery Stroke MOTOR MOVEMENTS

Strokes are more common than you probably imagine - one in six people will have one during their lifetime. Two thirds of those will suffer from paralysis of the arm as a result. That's why Swiss researchers are working on robots that can help stroke victims regain control over their arms and hands. Roger Gassert, a professor of rehabilitation engineering at ETH Zurich, has built a bunch of robotic devices over the years for training hand functions. But to use them, the patient must schedule an appointment and come to the clinic, limiting the amount of time they can spend with them. Somatosensory Functions So now, he's building devices that can be used at home. Together with Jumpei Arata from Kyushu University he's developed an exoskeleton for the hand that weighs just 120 grams but is strong enough to allow its user to grip and lift a bottle of mineral water. "Existing exoskeletons are heavy, and this is a problem for our patients because it renders them unable to lift their hands," Gassert said. "That's why we wanted to develop a model that leaves the palm of the hand more or less free, allowing patients to perform daily activities that support not only motor functions but somatosensory functions as well." The Power of Thought The next step is give patients the ability to command their robotic exoskeleton with the power of thought. "Especially with seriously affected patients, the connection between the brain and the hand is often severely or completely disrupted," Gassert said, "so we are looking for a solution that will help patients pass on commands to the robotic device intuitively." Other potential applications include leg prostheses that can help patients walk, and other muscle support systems.

Young Cocaine Users At Greater Risk For Stroke

Young Cocaine Users At Greater Risk For Stroke: A new study found that young cocaine users carry greater risk for ischemic stroke, which is due to a blood vessel blockage in or leading to the patient's brain. A blood clot often causes the blockage in this type of stroke. Ischemic stroke is also the most common stroke type.
