New Clues As To Why Some Older People May Be Losing Their Memory

New research links 'silent strokes,' or small spots of dead brain cells, found in about one out of four older adults to memory loss in the elderly. The study is published in the January 3, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.

"The new aspect of this study of memory loss in the elderly is that it examines silent strokes and hippocampal shrinkage simultaneously," said study author Adam M. Brickman, PhD, of the Taub Institute for Research on Alzheimer's Disease and the Aging Brain at Columbia University Medical Center in New York.

Researchers Discover How The Brain Merges Sights And Sounds

In order to get a better picture of our surroundings, the brain has to integrate information from different senses, but how does it know which signals to combine? New research involving scientists from the Max Planck Institute for Biological Cybernetics, the Bernstein Center for Computational Neuroscience Tubingen, the University of Oxford, and the University of Bielefeld has demonstrated that humans exploit the correlation between the temporal structures of signals to decide which of them to combine and which to keep segregated. This research is published in Current Biology.

Scripps Research Scientists Discover A Brain Cell Malfunction In Schizophrenia

Scientists at The Scripps Research Institute have discovered that DNA stays too tightly wound in certain brain cells of schizophrenic subjects. The findings suggest that drugs already in development for other diseases might eventually offer hope as a treatment for schizophrenia and related conditions in the elderly.

The research, now available online in the new Nature journal, Translational Psychiatry, shows the deficit is especially pronounced in younger people, meaning treatment might be most effective early on at minimizing or even reversing symptoms of schizophrenia, a potentially devastating mental disorder associated with hallucinations, delusions, and emotional difficulties, among other problems.
