Expert panel concludes neurostimulation can be life-changing therapy for chronic pain
Aug 14, 2014
A new report from an international team of experts provides comprehensive information on the safety and effectiveness of neurostimulation treatment for conditions including failed back surgery syndrome and complex regional pain syndrome. More studies are needed for conditions such as peripheral neuropathic pain, postamputation pain, and nerve pain from shingles.
Incidence of stroke in the elderly has dropped by 40% over the last 20 years
Jul 18, 2014
A new analysis of data from 1988-2008 has revealed a 40% decrease in the incidence of stroke in Medicare patients 65 years of age and older. This decline is greater than anticipated considering this population's risk factors for stroke, and applies to both ischemic and hemorrhagic strokes. Their findings are published in the July issue of The American Journal of Medicine.
Sleep after learning encourages growth of dendritic spines, enhances memory
Jun 06, 2014
In study published today in Science, researchers at NYU Langone Medical Center show for the first time that sleep after learning encourages the growth of dendritic spines, the tiny protrusions from brain cells that connect to other brain cells and facilitate the passage of information across synapses, the junctions at which brain cells meet. Moreover, the activity of brain cells during deep sleep, or slow-wave sleep, after learning is critical for such growth.
Predicting which stroke patients will be helped—or harmed—by clot-busting treatment
May 20, 2014
Johns Hopkins researchers say they have developed a technique, which uses standard MRI scans to measure damage to the blood-brain barrier, that can predict—with 95% accuracy—which stroke victims will benefit from intravenous, clot-busting drugs and which will suffer dangerous and potentially lethal bleeding in the brain.
Study links severe sleep apnea to increased risk of stroke, cancer, and death
Apr 15, 2014
Results of a 20-year follow-up study show that people with moderate to severe obstructive sleep apnea were 4 times more likely to die, nearly 4 times more likely to have a stroke, 3 times more likely to die from cancer, 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.
Meta-analysis: any blood pressure reading above normal may increase risk of stroke
Mar 13, 2014
Anyone with blood pressure that’s higher than the optimal 120/80 mm Hg may be more likely to have a stroke, according to a new meta-analysis published in the March 12, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
