Link discovered between depression and changes in the brain in Alzheimer's disease
A lifetime history of depression is associated with increased plaques and tangles in the brains of those with Alzheimer's disease and more rapid cognitive decline, according to a study by researchers at the Alzheimer's Disease Research Center at Mount Sinai School of Medicine. view more (2006-02-07)
Visual impairment associated with increased mortality risk
Individuals age 49 and older with cataract and those age 49 to 74 years with age-related macular degeneration appear to have higher mortality rates over an 11-year period than those without such visual impairments. view more (2007-07-10)
Abstinent alcoholics can have reduced brain activation without apparent structural damage
Researchers know that heavy alcohol intake can lead to structural and functional changes in the brain, but have not been able to establish direct links between these changes and specific cognitive functions. view more (2007-08-28)
Surgery not linked to memory problems in older patients
For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study from researchers at Washington University School of Medicine in St. Louis questions those assumptions. view more (2009-11-20)
Thyrotropin levels associated with Alzheimer's disease risk in women
Women with low or high levels of the hormone thyrotropin, which affects thyroid gland function and thyroid hormone levels, appear to have a higher risk of developing Alzheimer's disease, according to a report in the July 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. view more (2008-07-29)
Molecule links Down syndrome to Alzheimer's
Researchers from the Institute of Psychiatry at King's College London have identified a molecule that could be targeted to treat the cognitive impairment in people with Down syndrome. view more (2005-12-06)
Yerkes Researchers Use Eye Tracking to Detect Mild Dementia In Humans
Researchers at the Yerkes National Primate Research Center, Emory University, developed a test in nonhuman primates that is now using infrared eye tracking to detect mild cognitive impairment (MCI) in humans. view more (2009-04-16)
Cognitive Decline Begins in Late 20s, U.Va. Study Suggests
A new study indicates that some aspects of peoples' cognitive skills - such as the ability to make rapid comparisons, remember unrelated information and detect relationships - peak at about the age of 22, and then begin a slow decline starting around age 27. view more (2009-03-20)

Workplace alcohol use and impairment directly affects an estimated 15 percent of the U.S. workforce, or 19.2 million workers. view more (2006-01-11)
Reduced brain volume may predict dementia in healthy elderly people
Reduced volume, or atrophy, in parts of the brain known as the amygdala and hippocampus may predict which cognitively healthy elderly people will develop dementia over a six-year period. view more (2006-01-03)
Vision and hearing loss often occur together in older age
Older adults with vision loss may be more likely to also have hearing loss, and the opposite appears true as well. view more (2006-10-10)
Online cognitive behavioral therapy is effective in treating chronic insomnia
A study in the June 1 issue of the journal SLEEP demonstrates that online cognitive behavioral therapy (CBT) for chronic insomnia significantly improves insomnia severity, daytime fatigue, and sleep quality. view more (2009-06-01)
End-of-life treatment preferences may change as health declines
A study of older adults with advanced chronic illnesses indicates that as a patient's health declines, that individual may be more likely to accept treatments that would result in mild to severe functional disability. view more (2006-04-25)
Effects of new sleep medication appear unlikely to have potential for abuse or cognitive impairment
In a study of 14 adults with histories of sedative abuse, the newly approved sleep medication ramelteon does not appear to have effects that indicate potential for abuse or motor or cognitive impairment. view more (2006-10-03)
In-home sensors spot dementia signs in elderly
An Oregon Health & Science University study shows motion and door sensors placed in elders' homes can help track activity patterns thought to relate to memory changes that are early signs of dementia. view more (2006-07-28)
Brain Abnormality Found In Alzheimer's Disease Related to Gait Impairment in Older Persons
A new study from Rush University MedicalCenter helps explain why gait problems are often progressive in old age and related to risk of dementia and death. view more (2006-01-26)
New studies reveal that night-time acid reflux can impact sleep
According to results of a survey presented at the 72nd Annual Scientific Meeting of the American College of Gastroenterology, nighttime acid reflux, along with some of the less typical manifestations or symptoms of gastroesophageal reflux disease (GERD), is associated with significant sleep impairment. view more (2007-10-15)
Molecular imaging sheds new light on progression of Alzheimer's disease
In the past, physicians were able only to follow the progression of Alzheimer's disease (AD) through careful clinical histories, noting the often subtle changes associated with cognitive decline over a number of years. view more (2008-06-17)
