Algorithm for mapping mild cognitive impairment
10-29-2007 · EurekAlert!Despite intensive use of the term "mild cognitive impairment" to describe an intermediate stage of cognitive decline between normal and pathological brain ageing, no formally agreed process of characterizing this condition exists, say Fiona Matthews (MRC Biostatistics Unit, Cambridge, UK) and colleagues.

- Innovative 3D-imaging technique captures brain damage linked to Alzheimer's disease
10-11-2007 · EurekAlert!
Using an advanced three-dimensional mapping technique developed by UCLA researchers, the team analyzed magnetic resonance imaging data from 24 patients with amnestic mild cognitive impairment and 25 others with mild Alzheimer's disease. The research team found that patients with mild Alzheimer's had 10 to 20 percent more atrophy in most cortical areas than did MCI patients.

- 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.

01-16-2008 · EurekAlert!
Georgia Tech and Emory University researchers have developed a device that may allow patients to take a brief, inexpensive test that could be administered as part of a routine yearly checkup at a doctor's office to detect mild cognitive impairment -- often the earliest stage of Alzheimer's.

04-09-2007 · EurekAlert!
Individuals with diabetes may have a higher risk of developing mild cognitive impairment, a condition that involves difficulties with thinking and learning and may be an intermediate step toward Alzheimer's disease, according to a report in the April issue of Archives of Neurology, one of the JAMA/Archives journals.

- Brain scans show early Alzheimer's disease in people with memory problems
05-07-2007 · EurekAlert!
Brain scans of people with mild cognitive impairment show signs of early Alzheimer's disease, according to a study published in the May 8, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology.

- New imaging technique identifies people-at-risk for Alzheimer's disease
12-20-2006 · EurekAlert!
UCLA researchers used innovative brain scan technology with a new imaging molecule, invented at UCLA, to show that abnormal brain protein deposits that define Alzheimer's disease can be detected in people with mild cognitive impairment, a condition affecting 15-20 million Americans that increases risk for developing Alzheimer's disease. The new imaging technique helped researchers track disease progression over a two-year period and may be helpful in detecting pre-Alzheimer's conditions.

- Brain structure changes years before memory loss begins
04-16-2007 · EurekAlert!
People who develop dementia or Alzheimer's disease experience brain structure changes years before any signs of memory loss begin, according to a study published in the April 17, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology. Researchers say these findings may help identify people at risk of developing mild cognitive impairment, which leads to Alzheimer's disease.

- A drink a day may delay dementia
05-21-2007 · EurekAlert!
In people with mild cognitive impairment, up to one drink of alcohol a day may slow their progression to dementia, according to a study published in the May 22, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology. Mild cognitive impairment is a transitional stage between normal aging and dementia that is used to classify people with mild memory or cognitive problems and no significant disability.

- High-normal uric acid linked with mild cognitive impairment in the elderly
01-01-2007 · EurekAlert!
Researchers at the Johns Hopkins and Yale university medical schools have found that a simple blood test to measure uric acid, a measure of kidney function, might reveal a risk factor for cognitive problems in old age. Of 96 community-dwelling adults aged 60 to 92 years, those with uric-acid levels at the high end of the normal range had the lowest scores on tests of mental processing speed, verbal memory and working memory.
