MRI brain scans accurate in early diagnosis of Alzheimer's disease
Date:12/18/2008

ptoms, and autopsy is currently the only definitive way a diagnosis can be confirmed. The diagnosis often includes a medical history, mental status tests, neurological evaluations and blood tests. Physicians typically use brain scans only to exclude conditions that can also cause memory deficits, such as strokes and brain tumors.

The Florida researchers used a new visual rating system to evaluate the severity of shrinkage, or atrophy, in the brain's medial temporal lobe specifically in three structures essential for the conscious memory of facts and events. They compared the MRI brain scans of 260 people -- a group with probable Alzheimer's disease, two groups with varying degrees of mild cognitive impairment (mild memory problems), and a control group of normal elderly with no discernable memory loss. They found that scores generated by this MRI-facilitated test accurately distinguished each group from the other and correlated with the types of memory problems most frequently caused by Alzheimer's disease. The more extensive the brain atrophy, the more advanced the clinical stage of Alzheimer's disease.

The researchers even found brain atrophy in some people without memory complaints at the study's onset who demonstrated memory decline when assessed a year or two later. This suggests MRIs could predict who will get the disease well before signs of dementia become apparent by other diagnostic methods as well as rule out an Alzheimer's diagnosis in people experiencing memory problems, Dr. Duara said. "If you don't have changes in these three particular areas of the brain, then you don't have Alzheimer's."

Researchers at centers like Miami's Wien Center and USF's Byrd Institute are developing new Alzheimer's drugs that attack mechanisms leading to the death of nerve cells and their connections. The emergence of these disease-modifying treatments has made an earlier diagnosis of Alzheimer's increasingly important, Dr. Duara said. "Havin
