Scientists say they have found a way to distinguish between different types of dementia without the need for invasive tests, like a lumbar puncture.

US experts could accurately identify Alzheimer's disease and another type of dementia from structural brain patterns on medical scans, Neurology reports.

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.
