Tests of cognitive function are the best way so far to predict whether healthy elderly people will develop Alzheimer's

Although Alzheimer's disease begins long before symptoms appear, early diagnosis of Alzheimer's has so far been elusive. And given that there is no cure for the disease, benefits of early detection remain questionable.

Lead exposures early in life combined with high blood pressure in working age adults may lead to diminishing cognitive abilities in later life

Exposure to lead in early childhood and adolescence may contribute to hypertension-related decline that can impair a person's cognitive abilities, according to a new study presented at the 2005 American Heart Association's High Blood Pressure Research meeting.

"Designer" rats help show how declining estrogen after menopause can affect hypertension

Scientists at Wake Forest University School of Medicine have created a better research rat – the first to enable them to study how declining estrogen after menopause can affect hypertension, heart failure and kidney damage.

New approach to treating brain aneurysm combining the use of intracranial stents and coil embolization

A fender-bender may have saved Douglas Collins' life. A CT scan following the accident discovered Collins, 64, had a brain aneurysm, a weakness in the arterial wall that if ruptured could cause a stroke or death. It was not caused by the accident, but likely could have been a ticking time bomb present for years. The aneurysm was large and previously thought to require open surgery and a lengthy recovery.

Research highlights the role of viral sequence analysis in improving our overall understanding of hepatitis A cases in the U.S.

Novel use of genetic testing methods helped public health officials control and limit the further spread of four outbreaks of foodborne hepatitis A virus in 2003 related to the consumption of green onions, according to a detailed analysis published in the October 15 issue of The Journal of Infectious Diseases, now available online.

Study shows that nursing homes should consider diabetes a significant risk factor for falling

Falling is the leading cause of accidental death for elderly people, and a new study from Columbia University Medical Center and NewYork-Presbyterian Hospital/The Allen Pavilion suggests that nursing home residents with diabetes are four times more likely to fall than those who are not diabetic.
