TUESDAY, Aug. 19 (HealthDay News) -- Yearly changes in a person's performance on cognitive testing may be associated with dementia, new research suggests.
Using a newly developed model to assess the effect of variations in a person's score from year to year, researchers found that just a one point change in variability on cognitive test scores could indicate as much as a fourfold increase in the risk of developing dementia.

WEDNESDAY, Aug. 13 (HealthDay News) -- Physical frailty among the elderly may be linked to early Alzheimer's disease, regardless of whether or not patients develop dementia, new research reveals.
The finding, based on brain autopsies of deceased elderly patients, raises the notion that motor impairment in the elderly is an early symptom of Alzheimer's -- one that appears before mental decline.
It could also turn out to be that frailty and Alzheimer's are not directly linked but stem from a common origin, researchers say.

TUESDAY, Aug. 12 (HealthDay News) -- PET scans may provide doctors with a non-invasive method of detecting Alzheimer's disease-related brain plaques, Finnish researchers say.
Currently, the only reliable way to assess the presence of such plaques is through analysis of brain tissue samples obtained when a patient is alive or after death. In their study, University of Kuopio researchers examined 10 patients without severe dementia who'd undergone a biopsy of their brain's frontal cortex to check for normal-pressure hydrocephalus, an abnormal increase of cerebrospinal fluid in the brain.

WEDNESDAY, July 30 (HealthDay News)-- New reports on very different approaches to treating Alzheimer's disease could one day lead to better therapies for the mind-robbing condition, experts say.
A trio of studies that were expected to be presented Wednesday at the Alzheimer's Association 2008 International Conference on Alzheimer's Disease in Chicago noted progress made on three different treatment fronts.

WEDNESDAY, July 30 (HealthDay News) -- People whose mothers have had Alzheimer's disease may be predisposed to the mind-robbing condition, a new study finds.
The link may be a dysfunction in how the brain handles sugar -- something that's probably genetic and starts years before symptoms of Alzheimer's appear, researchers say.

WEDNESDAY, July 30 (HealthDay News) -- If you are single and in your 40s, it might be a healthy idea to get hitched.
A new Scandinavian study found unmarried middle-aged people are more likely to develop cognitive impairment than their partnered counterparts.

TUESDAY, July 29 (HealthDay News) -- A drug that aims to reduce the clogging "tangles" in the brain cells of people with Alzheimer's disease appears promising in early trials, researchers report.
Further studies are necessary to confirm whether the medication is as effective at slowing Alzheimer's as it seems, or whether it needs to be given as part of a cocktail of treatments.

TUESDAY, July 29 (HealthDay News) -- Scientists may be succeeding in the hunt for biomarkers for Alzheimer's disease.
A biomarker -- something that can be measured and that gives an indication of what's going on inside the body -- will help in early detection, in testing new therapies and, once doctors have better drugs for Alzheimer's, with earlier intervention in the disease process.
