New diagnostics are currently being developed by researchers to help doctors ascertain risk factors for Alzheimer's Disease before the onset of symptoms. A recent study showed that a brain scan lasting no longer than 5 minutes could potentially yield results indicative of dementia risk by determining how much blood flow and oxygenation the brain is receiving. Combined with two recommended interventions to reduce risk for dementia -- switching to a healthier diet and adhering to a regular exercise regimen -- scientists are beginning to make headway in addressing the disease, for which there is currently no known cure of FDA-approved therapies that treat the underlying condition.
According to the findings of Swiss researcher Sven Haller of the University of Geneva and his team, screening before memory loss even manifests would allow time for early and preventive treatment. While it was not clearly established if reduced blood flow to the brain causes memory loss, or if the reverse is true, meaning brain damage reduces blood flow, an MRI scan can still be useful in predicting who are more likely to develop Alzheimer's dis
