MRI may predict continued decline in patients with mild cognitive impairment
Date:10/4/2010

OAK BROOK, Ill. Using advanced MRI and an artificial intelligence technique, researchers in Geneva, Switzerland, have identified a method that may help identify which individuals with mild cognitive impairment (MCI) will continue to decline, according to a study published online and in the December issue of Radiology.

"We know that about half of all individuals with early-stage mild cognitive impairment will progress to Alzheimer's disease," said lead researcher Sven Haller, M.D, M.Sc., a radiologist at University Hospitals of Geneva. "But not knowing which patients will continue to decline makes it difficult to treat Alzheimer's early in the disease process."

Haller and a team of researchers used two novel techniques to image the brains of 35 control participants (mean age 63.7) and 69 patients with MCI (mean age 65 years), including 38 women and 31 men. Patients were diagnosed with MCI based on a battery of neuropsychological tests, which were repeated on 67 of the patients one year later to determine whether their disease was stable (40 patients) or progressive (27 patients).

Using an advanced technique called susceptibility-weighted MRI, the researchers were able to generate scans with greater detail of the many blood vessels in the brain, including the presence of tiny leaks called microhemorrhages or microbleeds.

"The number of cerebral microbleeds was significantly higher in the individuals with mild cognitive impairment than those in the control group," Dr. Haller said.

The MRI scans revealed microbleeds in 33 percent of individuals with stable MCI and 54 percent of those with progressive MCI. Only 14 percent of the control participants had microbleeds.

The susceptibility-weighted MRI also revealed that compared to the control participants, individuals with MCI had significantly increased iron concentration in certain areas deep within the structure of the brain and reduced levels of iron i
