Brain-injured war veterans show a faster decline in cognitive functioning as they age
12-18-2007 · EurekAlert!A study of Vietnam war veterans who suffered brain injuries during the conflict has found that the men show a faster decline in their cognitive functioning as they grow older than veterans without such injuries.

- Cognitive scores vary as much within test takers as between age groups making testing less valid
07-01-2007 · EurekAlert!
How precise are tests used to diagnose learning disability, progressive brain disease or impairment from head injury? Timothy Salthouse, Ph.D., a noted cognitive psychologist at the University of Virginia, has demonstrated that giving a test only once isn't enough to get a clear picture of someone's mental functioning. It appears that repeating tests over a short period may give a more accurate range of scores, improving diagnostic workups.

- Brains scans of symptomatic Gulf War veterans show differences
05-01-2007 · EurekAlert!
Veterans of the first Gulf War who returned with multiple health symptom complaints show significant differences in brain structures from their fellow returnees without high numbers of health symptoms, according to research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28-May 5, 2007.

- Children with gene show reduced cognitive function
11-05-2007 · EurekAlert!
Children possessing a gene known to increase Alzheimer's disease risk already show signs of reduced cognitive function, an Oregon Health & Science University study has found. Scientists discovered that 7- to 10-year-olds with a member of a family of genes implicated in development, nerve cell regeneration and neuroprotection display reduced spatial learning and memory, associated with later-life cognitive impairments. This suggests brain changes predisposing a person to Alzheimer's might occur much sooner than previously thought.

- Cognitive 'fog' of normal aging linked to brain system disruption
12-05-2007 · EurekAlert!
Comparisons of the brains of young and old people have revealed that normal aging may cause cognitive decline due to deterioration of the connections among large-scale brain systems. The researchers linked the deterioration to a decrease in the integrity of the brain's "white matter," the tissue containing nerve cells that carry information. The researchers found that the disruption occurred even in the absence of pathology associated with Alzheimer's disease.

- Cognitive training for older adults may help slow decline of daily functioning abilities
12-19-2006 · EurekAlert!
Older adults who received cognitive training reported improved cognitive function for up to five years afterwards and less decline in the ability to perform daily activities as compared to those who did not receive the training, according to a study in the Dec. 20 issue of JAMA.

- Poor sleep associated with cognitive decline in elderly women
07-16-2007 · EurekAlert!
Women who experienced cognitive decline over a 13 to 15 year period after age 65 were more likely to sleep poorly than women whose cognition did not decline, according to a study led by researchers at the San Francisco VA Medical Center (SFVAMC).

- Columbia researchers identify brain network that may help prevent or slow Alzheimer's
08-20-2007 · EurekAlert!
Columbia University Medical Center researchers, led by principal investigator Yaakov Stern, Ph.D., a professor at the Taub Institute for the Research on Alzheimer's Disease and the Aging Brain, have identified a brain network within the frontal lobe that is associated with cognitive reserve, the process that allows individuals to maintain function despite brain function decline due to aging or Alzheimer's disease.

- Researchers use novel three-dimensional imaging technique
10-24-2006 · EurekAlert!
Using an innovative three-dimensional imaging technique, a team of UCLA researchers have tracked how Alzheimer's disease spreads through the hippocampus -- the area of the brain linked with memory -- in a pattern consistent with the known trajectory of neurofibrilliary tangle dissemination, an accumulation of diseased proteins in the brain cells. They found that three areas within the hippocampus of Alzheimer's patients show more atrophy compared with those in patients having amnestic mild cognitive impairment.

- Nerve fibers need specific growth factor chemical to form connections within the brain
11-17-2006 · EurekAlert!
A discovery on how neural circuitry develops to aid proper cerebral cortex activity may help explain the memory and cognitive decline seen in Alzheimer's disease patients -- a discovery that could point toward potential treatments, according to UC Irvine scientists.

- Study suggests some brain injuries reduce the likelihood of post-traumatic stress disorder
12-23-2007 · EurekAlert!
A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder. The findings, from the National Institutes of Health and the National Naval Medical Center, suggest that drugs or pacemaker-like devices aimed at dampening activity in these brain regions might be effective treatments for PTSD.
