A psychology researcher at North Carolina State University is proposing a new theory to explain why older adults show declining cognitive ability with age, but don’t necessarily show declines in the workplace or daily life. One key appears to be how motivated older adults are to maintain focus on cognitive tasks.

As part of a multinational, collaborative effort, researchers from the Broad Institute, Massachusetts General Hospital (MGH), and scores of other institutions from all over the world have helped identify over 100 locations in the human genome associated with the risk of developing schizophrenia in what is the largest genomic study published on any psychiatric disorder to date. The findings, which are published online in Nature, point to biological mechanisms and pathways that may underlie schizophrenia, and could lead to new approaches to treating the disorder, which has seen little innovation in drug development in more than 60 years.

In the complex environment of a spinal cord injury, researchers have found that immune cells in the central nervous system of elderly mice fail to activate an important signaling pathway, dramatically lowering chances for repair after injury.

 Researchers believe they have learned how mutations in the gene that causes Huntington’s disease kill brain cells, a finding that could open new opportunities for treating the fatal disorder. Scientists first linked the gene to the inherited disease more than 20 years ago.
