ST. PAUL, Minn. – A first of its kind study examining the effects of methamphetamine use during pregnancy has found the drug appears to cause abnormal brain development in children. The research is published in the April 15, 2009, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Oslo, Norway – April 15, 2009 – The Hong Kong flu pandemic was responsible for more than 700,000 deaths worldwide in the late 1960s, with major disease outbreaks in Europe in the winter of 1969-1970. A number of studies have been conducted to determine if prenatal exposure to the influenza virus may result in mental disorders that affect a small portion of the population, but no studies have explored the possible effects of prenatal exposure on the mean intelligence in the general population.
PROVIDENCE, RI – Researchers at Rhode Island Hospital have found that cognitive behavioral therapy (CBT) can reduce the frequency of seizures in patients with psychogenic nonepileptic seizures (PNES), along with improving their overall quality of life. The study was published in the April 2009 edition of Epilepsy and Behavior.
New research suggests that neurodegenerative diseases are neither diffuse nor random but specifically target large-scale functional networks in the human brain. The study, published by Cell Press in the April 16 issue of the journal Neuron, may drive a new generation of network-based strategies for diagnosing and monitoring neurodegenerative diseases.
New research provides insight into how the brain can execute different actions in response to the same stimulus. The study, published by Cell Press in the April 16 issue of the journal Neuron, suggests that information from single brain cells cannot be interpreted differently within a short time period, a finding that is important for understanding both normal cognition and psychiatric disorders.
Scientists are reporting the strongest evidence to date that neurodegenerative diseases target and progress along distinct neural networks that normally support healthy brain function. The discovery could lead to earlier diagnoses, novel treatment-monitoring strategies, and, possibly, recognition of a common disease process among all forms of neurodegeneration.
Researchers at the Yerkes National Primate Research Center, Emory University, developed a test in nonhuman primates that is now using infrared eye tracking to detect mild cognitive impairment (MCI) in humans. The researchers hope the advanced technology will be helpful in predicting the onset of Alzheimer's disease. The test, which is featured in the current online issue of The American Journal of Alzheimer's Disease and Other Dementias, is helping researchers further understand the role of the brain structures critical to human memory.
Westchester, Ill. – A study in the April 15 issue of the Journal of Clinical Sleep Medicine is the first to assess the effectiveness of treating sleep disorders in adults with a traumatic brain injury (TBI). Results indicate that treatment may result in the objective resolution of the sleep disorder without improvements in daytime sleepiness or neuropsychological function.
Westchester, Ill. - A study in the April 15 issue of the Journal of Clinical Sleep Medicine determined that over-the-counter melatonin medication can shorted the length of time it takes for children with autistic spectrum disorder (ASD), Fragile X Syndrome (FXS), or both to fall asleep at the beginning of the night.
Runners clutching bottles of energy drink are a common sight, and it has long been known that sugary drinks and sweets can significantly improve athletes' performance in endurance events. The question is how?
Clearly, 'sports' drinks and tablets contain calories. But this alone is not enough to explain the boost, and the benefits are felt even if the drink is spat out rather than swallowed. Nor does the sugary taste solve the riddle, as artificial sweeteners do not boost performance even when they are indistinguishable from real sugars.
When we look at a scene in front of us, we need to focus on the important items and be able to ignore distracting elements. Studies have suggested that inhibition of return (in which our attention is less likely to return to objects we've already viewed) helps make visual search more efficient – when searching a scene to find an object, we have a bias toward inspecting new regions of a scene, and we avoid looking for the object in already searched areas. Psychologists Michael D.
Scientists have long been interested in the interplay of emotions and identity, and some have recently focused on cultural identity. One's heritage would seem to be especially stable and impervious to change, simply because it's been passed down generation after generation and is deeply ingrained in the collective psyche. But how deeply, exactly? Psychologists Claire Ashton-James of the University of British Columbia, William W.
We've heard it before: "Imagine yourself passing the exam or scoring a goal and it will happen." We may roll our eyes and think that's easier said than done, but in a new study in Psychological Science, a journal of the Association for Psychological Science, psychologists Christopher Davoli and Richard Abrams from Washington University suggest that the imagination may be more effective than we think in helping us reach our goals.
A recent study by Mount Sinai faculty suggests that a gene associated with onset of type-2 diabetes also decreases in Alzheimer's disease dementia cases. The research, led by Dr. Giulio Maria Pasinetti, MD, Ph.D., The Aidekman Family Professor in Neurology, and Professor of Psychiatry and Geriatrics and Adult Development at Mount Sinai School of Medicine, was published this week in the scientific journal, Archives of Neurology.
Nerve signals that tell the brain that we are being slowly stroked on the skin have their own specialised nerve fibres in the skin. This is shown by a new study from the Sahlgrenska Academy, University of Gothenburg, Sweden. The discovery may explain why touching the skin can relieve pain.
The specialised nerve fibres in the skin are called CT nerves (C-tactile) and they travel directly to the areas in the brain that are important in the emergence of feelings.
