The Parkinson’s Institute and Clinical Center announced research showing that intermittent nicotine treatment reduces medication-induced dyskinesias by as much as 50 percent in models of Parkinson’s disease. Lead by senior research scientist, Maryka Quik, Ph.D., the research will be published in an upcoming issue of the Annals of Neurology.
People with more years of education lose their memory faster than those with less education in the years prior to a diagnosis of dementia, according to a study published in the October 23, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology.
Results of a new study may one day help scientists learn how to enhance a naturally occurring mechanism in the brain that promotes resilience to psychological stress. Researchers funded by the National Institutes of Health’s National Institute of Mental Health (NIMH) found that, in a mouse model, the ability to adapt to stress is driven by a distinctly different molecular mechanism than is the tendency to be overwhelmed by stress. The researchers mapped out the mechanisms – components of which also are present in the human brain – that govern both kinds of responses.
The U.S. Food and Drug Administration today expanded the approved age range for Menactra, a bacterial meningitis vaccine, to include children ages 2 to 10 years.
Hilleke Hulshoff Pol presents persuasive evidence how genetic factors influence the brain structure opening new insights into the reciprocal gene-environment developmental pathways.
Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain, scientists have found in a study of human brain tissue. The researchers found that the gene is turned on at increasingly high rates during normal development of the prefrontal cortex, the part of the brain involved in higher functions like thinking and decision-making — but that this normal increase may not occur in people with schizophrenia.
At a time when established scientists are leaving academia because of a lack of funding for biomedical research and a potential new generation of scientists are considering whether to even enter a field with a competitive funding environment, the Ellison Medical Foundation in partnership with the American Federation for Aging Research (AFAR), has increased funding for two critical grant programs: the new Ellison Medical Foundation/AFAR Postdoctoral Fellows in Aging Research Program and the Julie Martin Mid-Career Awards in Aging Research.
A team of international researchers reported they have identified a group of cell-signaling proteins found in blood that serve as a unique “voiceprint” that can not only be used to diagnose Alzheimer’s disease, but also classify and predict presymptomatic individuals who will eventually develop the memory-robbing disorder.
Persons with multiple sclerosis who smoke risk increasing the amount of brain tissue shrinkage, a consequence of MS, and the subsequent severity of their disease, new research conducted at the Buffalo Neuroimaging Analysis Center (BNAC) at the University at Buffalo has shown.
Glutaric acidemia type I (GA-I) is an inherited disorder similar to Huntington disease. Individuals with GA-I are unable to breakdown completely the amino acids lysine and tryptophan and the intermediates of lysine and tryptophan breakdown accumulate in the brain. In most, but not all, affected children, a period of normal development is followed by an irreversible brain injury triggered by a nonspecific illness.
