Considered a standard gauge of intelligence, an intelligence quotient (IQ) score doesn't actually provide an accurate measure of one's intellect, according to a landmark study – the largest of its kind – led by Adrian Owen of the Brain and Mind Institute at Western. http://medicalxpress.com/news/2013-05-debunking-iq-myth.html Psychology & Psychiatry Tue, 07 May 2013 07:30:37 EST news287130628 Brain function in adults as young as 35 may decline as their heart disease risk factors increase, according to new research in the American Heart Association journal Stroke. http://medicalxpress.com/news/2013-05-heart-disease-factors-decrease-brain.html Cardiology Thu, 02 May 2013 17:12:01 EST news286733511 They identified blood-based biological markers that are associated with the build up of a toxic protein in the brain which occurs years before symptoms appear and irreversible brain damage has occurred. http://medicalxpress.com/news/2013-05-scientists-closer-screening-early-alzheimer.html Alzheimer's disease & dementia Wed, 01 May 2013 08:22:40 EST news286615351 (Medical Xpress)—New research from Cardiff and Bristol universities shows that children whose brains process information more slowly than their peers are at greater risk of psychotic experiences. http://medicalxpress.com/news/2013-04-children-brain-psychosis.html Psychology & Psychiatry Fri, 26 Apr 2013 08:00:01 EST news286180822 Risk prediction tools that estimate future risk of heart disease and stroke may be more useful predictors of future decline in cognitive abilities, or memory and thinking, than a dementia risk score, according to a new study published in the April 2, 2013, print issue of Neurology, the medical journal of the American Academy of Neurology. http://medicalxpress.com/news/2013-04-heart-problems-predictor-memory-loss.html Neuroscience Mon, 01 Apr 2013 16:00:06 EST news284036421 New research from Wake Forest Baptist Medical Center is giving radiation oncologists who treat brain tumors a better understanding of how to preserve the brain's functions while still killing cancer. http://medicalxpress.com/news/2013-03-toxicity-brain-cognition-cancer-patients.html Cancer Wed, 20 Mar 2013 11:30:08 EST news282997801 (Medical Xpress)—The effects of antiepileptic drugs during pregnancy have long been a concern of clinicians and women of childbearing age whose seizures can only be controlled by medications. In 1999, a study called the Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) began following the children of women who were taking a single antiepileptic agent during pregnancy. The drugs included carbamazepine, lamotrigine, phenytoin or valproate. http://medicalxpress.com/news/2013-03-fetal-exposure-antiepileptic-drug-valproate.html Neuroscience Wed, 20 Mar 2013 07:18:02 EST news282982655 (Medical Xpress)—Further evidence that a program of controlled, progressive aerobic exercise may help restore normal cognitive function in patients who have sustained a concussion has been published by researchers at the University at Buffalo School of Medicine and Biomedical Sciences. http://medicalxpress.com/news/2013-03-aerobic-post-concussion.html Neuroscience Thu, 07 Mar 2013 06:52:22 EST news281861529 Combining hospital MRIs with the mathematical tool known as network analysis, a group of researchers at UC San Francisco and UC Berkeley have mapped the three-dimensional global connections within the brains of seven adults who have genetic malformations that leave them without the corpus callosum, which connects the left and right sides of the brain. http://medicalxpress.com/news/2013-02-network-analysis-abnormal-brain-responsible.html Neuroscience Thu, 28 Feb 2013 16:20:52 EST news281290843 (Medical Xpress)—People living in urbanised environments are less able to concentrate on the task in hand than people who live in remote areas, according to research from Goldsmiths, University of London funded by the Economic and Social Research Council (ESRC). http://medicalxpress.com/news/2013-02-urban-environment-ability-tasks.html Psychology & Psychiatry Mon, 18 Feb 2013 05:51:48 EST news280389094 (Medical Xpress)—Too many athletes may be going back onto the field, court or rink too soon after a concussion, according to a new study that recommends athletes undergo post-exertion neurocognitive testing before being cleared to return to play. http://medicalxpress.com/news/2013-01-return-to-play-decisions-commonly-post-exertion-neurocognitive.html Health Thu, 31 Jan 2013 08:40:01 EST news278841524 (Medical Xpress)—Researchers from the Sorbonne in France have published the results of a study they carried out to determine if eating a Mediterranean diet helps prevent dementia as people age.
