Study suggests hope for better treatment of Alzheimers and stroke
Until now, scientists have been unable to distinguish between dementia caused by Alzheimers disease and that caused by poor blood flow to the brain. But, researchers at the San Francisco VA Medical Center have now used a combination of magnetic resonance imaging (MRI) and a related technique knows as MR spectroscopy to differentiate between the two kinds of dementia. Their work offers hope of improving the treatment of dementia in patients with poor blood flow, such as stroke victims, and the testing of drugs to treat Alzheimers disease (AD).
"Currently, there are no effective treatments for Alzheimers disease, but we do have options for treating vascular disease. So, being able to determine that there is a vascular component to a patients dementia would make a big difference in planning for treatment," said Norbert Schuff, PhD, a researcher in the Magnetic Resonance Unit at the San Francisco VA Medical Center and a UCSF associate professor of radiology.
