Mayo Clinic study using structural MRI may help accurately diagnose dementia patients

ROCHESTER, Minn. -- A new Mayo Clinic study may help physicians differentially diagnose three common neurodegenerative disorders in the future. The study will be presented at the Alzheimer's Association International Conference on Alzheimer's Disease on July 11 in Vienna.

Coronary artery bypass surgery not a risk factor for dementia

A study conducted by Mayo Clinic found that fears surrounding a connection between coronary artery bypass surgery and dementia are unwarranted. The link between CABG surgery and development of long-term cognitive decline has been controversial in medical literature. ''What we found is that in an observational study of residents of Rochester, Minn., CABG surgery was not a risk factor for dementia,'' says David Knopman, M.D., Mayo Clinic neurologist and the study's lead investigator. ''It was reassuring that the surgery was not associated with increased risk of dementia.''
