New Alzheimer-related memory disorder identified
Nov 14, 2014
A multi-institutional study has defined and established criteria for a new neurologic disease closely resembling Alzheimer disease called primary age-related tauopathy (PART). Patients with PART develop cognitive impairment that can be indistinguishable from Alzheimer disease, but they lack amyloid plaques. Awareness of this neurologic disease will help doctors diagnose and develop more effective treatments for patients with different types of memory impairment.
tPA’s tardy twin could aid in stroke recovery
Oct 22, 2014
Study findings suggest that in stroke, uPA's (urokinase-type plasminogen activator) benefits may extend beyond the time when doctors' principal goal is dissolving the blood clot that is depriving the brain of blood. Instead, uPA appears to help brain cells recover from the injuries induced by loss of blood flow. Treating mice with uPA after an experimental stroke can improve their recovery of motor function, the researchers found.
AAN: Risks of opioids outweigh benefits for headache, low back pain, other conditions
Sep 30, 2014
According to a new position statement from the American Academy of Neurology (AAN), the risk of death, overdose, addiction, or serious side effects with prescription opioids outweigh the benefits in chronic, non-cancer conditions such as headache, fibromyalgia, and chronic low back pain. The position paper is published in the September 30, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology.
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.
