The causes of learning problems associated with an inherited brain tumor disorder are much more complex than scientists had anticipated, researchers at Washington University School of Medicine in St. Louis report. The disorder, neurofibromatosis 1 (NF1), is among the most common inherited pediatric brain cancer syndromes. Children born with NF1 can develop low-grade brain tumors, but their most common problems are learning and attention difficulties. “While one of our top...

redOrbit Staff & Wire Reports - Your Universe Online One of the unique features of the human mind is its ability re-prioritize its goals and priorities as situations change and new information arises. This happens when you cancel a planned cruise because you need the money to repair your broke-down car, or when you interrupt your morning jog because your cell phone is ringing in your pocket. In a new study published in the Proceedings of the National Academy of Sciences (PNAS),...

Light instantly triggers or reverses depression-like states in rodents -- NIH-funded studies A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced...

Lawrence LeBlond for redOrbit.com - Your Universe Online It´s an undeniable fact that many teenagers are going to experiment with alcohol before they are mentally ready enough to do so. Now, a new study may help explain why some of these teenagers are more prone to continue drinking alcohol after trying it than others are. A study, led by researchers at King´s College London´s Institute of Psychiatry (IoP), provides the most detailed understanding yet of the brain process...

Parkinson's disease is a degenerative disorder of the central nervous system that is characterized by tremors, rigidity, slowness of movement, and difficulty walking. It is caused by loss of the neurons that produce the neurotransmitter dopamine (known as dopaminergic neurons). One of the primary goals in Parkinson's disease research is to develop a replacement for dopaminergic neurons. In this issue of the Journal of Clinical Investigation, researchers led by Takuya Hayashi at the RIKEN...

New MRI technique could help doctors track how patients respond to treatment A new imaging technique developed at MIT offers the first glimpse of the degeneration of two brain structures affected by Parkinson's disease. The technique, which combines several types of magnetic resonance imaging (MRI), could allow doctors to better monitor patients' progression and track the effectiveness of potential new treatments, says Suzanne Corkin, MIT professor emerita of neuroscience and leader of...

Transmission model shows two main hallmarks of Parkinson´s disease - death of dopamine neurons and disease protein clumps Understanding how any disease progresses is one of the first and most important steps towards finding treatments to stop it. This has been the case for such brain-degenerating conditions as Alzheimer's disease. Now, after several years of incremental study, researchers at the Perelman School of Medicine, University of Pennsylvania have been able to piece together...

Last year a clinical trial of L-DOPA -- a mainstay of Parkinson's disease therapy -- was launched for Angelman syndrome, a rare intellectual disorder that shares similar motor symptoms such as tremors and difficulty with balance. The clinical trial is based on a 10-year-old case report showing benefit with the drug, but few studies since have explored the neurological justification for using L-DOPA to treat parkinsonian features in Angelman syndrome. New research from the University of...
