However, their side effects can include serious neurological problems like nausea, headache, dizziness, hallucinations and even psychosis. In a recent Science publication, EPFL researchers have shown for the first time how sulfonamides can interfere with a patient's nervous system. http://medicalxpress.com/news/2013-05-antibiotics-sulfonamide-nervous-side-effects.html Medical research Thu, 23 May 2013 14:00:09 EST news288536311 Scientists at the National Institutes of Health report they have discovered in mouse studies that a small molecule released in the spinal cord triggers a process that is later experienced in the brain as the sensation of itch. http://medicalxpress.com/news/2013-05-scientists-molecule-triggers-sensation.html Medical research Thu, 23 May 2013 14:00:01 EST news288536360 (Medical Xpress)—The human brain is able to identify individuals' voices by comparing them against an internal 'average voice' prototype, according to neuroscientists. http://medicalxpress.com/news/2013-05-brain-internal-average-voice-prototype.html Neuroscience Thu, 23 May 2013 13:43:48 EST news288535418 Little is known about why asthma develops, how it constricts the airway or why response to treatments varies between patients.

Recent studies have uncovered a link between the mutations responsible for Gaucher disease and an increased risk of developing Parkinson's disease later in life. New research published online on May 23 in the Cell Press journal Cell Metabolism indicates that the neurodegeneration found in Gaucher disease stems from defects in processes that break down and remove unwanted material from cells. This defective trash removal in cells can lead to the toxic build-up of proteins found to be responsible for neurodegeneration in Parkinson's disease, providing insight into the link between the two diseases. http://medicalxpress.com/news/2013-05-defective-cellular-gaucher-patients-parkinson.html Parkinson's & Movement disorders Thu, 23 May 2013 12:14:20 EST news288530028 Family caregivers of older adults with dementia are less stressed and their moods are improved on days when dementia patients receive adult day services (ADS), according to Penn State researchers. http://medicalxpress.com/news/2013-05-adult-day-dementia-patients-stress.html Health Thu, 23 May 2013 12:10:58 EST news288529840 Treating pediatric leukemia patients with a liposomal formulation of anthracycline-based chemotherapy at a more intense-than-standard dose during initial treatment may result in high survival rates without causing any added heart toxicity, according to the results of a study published online today in Blood, the Journal of the American Society of Hematology (ASH). http://medicalxpress.com/news/2013-05-chemo-regimen-childhood-leukemia-high.html Cancer Thu, 23 May 2013 12:10:12 EST news288529804 Spanish researchers have discovered that the daily clearance of neutrophils from the body stimulates the release of hematopoietic stem cells from the bone marrow into the bloodstream, according to a report published today in the journal Cell. http://medicalxpress.com/news/2013-05-discarded-immune-cells-relocation-stem.html Medical research Thu, 23 May 2013 12:07:44 EST news288529649 A brief visual task can predict IQ, according to a new study.

Recent estimates suggest that only about half of school-age children meet this evidence-based guideline for promoting better health and development. The report recommends that most daily physical activity occur during regular school hours in physical education classes, recess or breaks, and classroom exercises, with additional opportunities available through active commutes to and from school, before- and after-school programs, and participation in intramural or varsity sports. http://medicalxpress.com/news/2013-05-schools-opportunities-minutes-daily-physical.html Health Thu, 23 May 2013 11:52:06 EST news288528720 Bochum's medics have succeeded in treating cerebral palsy with autologous cord blood. Following a cardiac arrest with severe brain damage, a 2.5 year old boy had been in a persistent vegetative state – with minimal chances of survival. Just two months after treatment with the cord blood containing stem cells, the symptoms improved significantly; over the following months, the child learned to speak simple sentences and to move. http://medicalxpress.com/news/2013-05-successful-treatment-pediatric-cerebral-palsy.html Medical research Thu, 23 May 2013 11:51:31 EST news288528685 As the human body fine-tunes its neurological wiring, nerve cells often must fix a faulty connection by amputating an axon—the "business end" of the neuron that sends electrical impulses to tissues or other neurons. It is a dance with death, however, because the molecular poison the neuron deploys to sever an axon could, if uncontained, kill the entire cell. http://medicalxpress.com/news/2013-05-secret-deaths-neurons.html Neuroscience Thu, 23 May 2013 11:50:43 EST news288528637 A study by researchers at Henry Ford Hospital found "substantial evidence" that a regenerative process involving damaged nerve fibers in the spinal cord could hold the key to better functional recovery by most stroke victims. http://medicalxpress.com/news/2013-05-regenerating-spinal-cord-fibers-treatment.html Neuroscience Thu, 23 May 2013 11:50:08 EST news288528379 Frequent heartburn was positively associated with cancers of the throat and vocal cord among nonsmokers and nondrinkers, and the use of antacids, but not prescription medications, had a protective effect, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2013-05-frequent-heartburn-cancers-throat-vocal.html Cancer Thu, 23 May 2013 11:33:02 EST news288527567 Researchers at Lund University have succeeded in preventing very early symptoms of Huntington's disease, depression and anxiety, by deactivating the mutated huntingtin protein in the brains of mice. http://medicalxpress.com/news/2013-05-breakthrough-huntington-disease.html Neuroscience Thu, 23 May 2013 11:32:40 EST news288527467 Nervous about that upcoming job interview?
