A University of Iowa study finds that patients treated with a short course of antidepressants after a stroke have significantly greater improvement in physical recovery than patients treated with a placebo. Moreover, the study is the first to demonstrate that this physical recovery continues to improve for at least nine months after the antidepressant medication is stopped.
Brain
Patients with a temporary surgical implant have used regions of the brain that control speech to "talk" to a computer for the first time, manipulating a cursor on a computer screen simply by saying or thinking of a particular sound.
"There are many directions we could take this, including development of technology to restore communication for patients who have lost speech due to brain injury or damage to their vocal cords or airway," says author Eric C. Leuthardt, MD, of Washington University School of Medicine in St. Louis.
Workers exposed to welding fumes may be at increased risk of damage to the same brain area harmed by Parkinson's disease, according to a new study by researchers at Washington University School of Medicine in St. Louis.
Fumes produced by welding contain manganese, an element that scientists have linked to neurological problems including Parkinson's disease-like symptoms.
TORONTO, Ont., April 7, 2011 – Virtual reality and other video games can significantly improve motor function in stroke patients, according to research from St. Michael's Hospital.
Patients who played video games, such as Wii and Playstation, were up to five times more likely to show improvements in arm motor function compared to those who had standard therapy.
Ann Arbor, Mich. -- In a paper published today in the professional health care journal, Health Affairs, Blue Cross Blue Shield of Michigan and the University of Michigan Health System report that their model for collaborative health care quality improvement has measurably improved safety and quality in several clinical areas, and has saved millions in health care costs.
WASHINGTON, April 7, 2011 – We've all watched it unfold on soap operas, medical dramas and films: A patient falls into a coma, and loved ones at the bedside try to peel away the veil by talking or reading aloud. Some of us have done it ourselves, desperately hoping for any hint of wakening or awareness.
For Theresa Louise-Bender Pape, who studies patients with traumatic brain injury in various stages of coma and recovery, the "it can't hurt" reasoning just isn't good enough. She needs evidence. She wants answers.
WASHINGTON – Men who are abused by their female partners can suffer significant psychological trauma, such as post-traumatic stress disorder, depression and suicidal thoughts, according to two new papers published by the American Psychological Association.
Tampa, FL (April 7, 2011) -- Deep brain stimulation, a surgical procedure to suppress faulty nerve signals, allowed 77 percent of patients to stop the medications used to treat their essential tremors within one year following the surgery, University of South Florida researchers report.
If mice commuted, their brains might find it progressively harder to navigate the maze of Los Angeles freeways.
A new study reveals that after short-term exposure to vehicle pollution, mice showed significant brain damage — including signs associated with memory loss and Alzheimer's disease.
The mind-numbing toxin is not an exhaust gas, but a mix of tiny particles from burning of fossil fuel and weathering of car parts and pavement, according to the study to be published Thursday, April 7 in the leading journal Environmental Health Perspectives.
Long term users of the popular recreational drug ecstasy (MDMA) risk structural brain damage, suggests preliminary research published online in the Journal of Neurology, Neurosurgery and Psychiatry.
Other research has suggested that people who use ecstasy develop significant memory problems, so the Dutch researchers wanted to find out if there was any clinical evidence of structural changes in the brain to back this up.
They focused on the hippocampus, which is the area of the brain responsible for long term memory.
Epileptic seizures can precede the development of a subsequent brain tumour by many years, suggests research published online in the Journal of Neurology, Neurosurgery and Psychiatry.
The risk seems to be greatest among those aged between 15 and 44 when first admitted to hospital for an epileptic seizure, the findings show.
The researchers base their findings on first time admissions for epilepsy from the Oxford Record Linkage Study (ORLS) for 1963 to 1998, and national Hospital Episode Statistics (HES) data for England for 1999 to 2005.
Contagious yawning is not just a marker of sleepiness or boredom. For chimpanzees, it may actually be a sign of a social connection between individuals.
New research at the Yerkes National Primate Research Center, Emory University, may help scientists understand empathy, the mechanism thought to underlie contagious yawning, in both chimpanzees and humans. The research also may help show how social biases strengthen or weaken empathy.

New Findings Suggest Novel Avenues to Explore Taste Loss in Autoimmune Diseases
COLUMBUS, Ohio – The persistent fatigue that plagues one out of every three breast cancer survivors may be caused by one part of the autonomic nervous system running in overdrive, while the other part fails to slow it down.
That imbalance of a natural system in the body appears linked to the tiredness and exhaustion that can burden cancer patients as much as a decade after their successful treatment.
