London: A new brain scan method can help distinguish between different types of dementia with 75 percent accuracy, and without the need for invasive tests, scientists claim.Using the new method, US experts could accurately identify Alzheimer`s disease and another type of dementia from structural brain patterns on medical scans.Currently, doctors can struggle to diagnose dementia, meaning the most appropriate treatment may be delayed. More invasive tests can help, but are unpleasant for the patient.Despite being two distinct diseases, Alzheimer`s and frontotemporal dementia, share similar clinical features and symptoms and can be hard to tell apart without medical tests.
