Washington, Nov 25 (PTI) Researchers have found a biomarker that identifies a rare brain disease called corticobasal degeneration (CBD) with higher accuracy than traditional diagnostic methods, according to a study.

The biomarker that identifies a primary tauopathy increases CBD detection accuracy to 89 per cent compared to traditional methods that are only 25 per cent to 50 per cent accurate, scientists at the Washington University said.

Primary tauopathies are a group of rare brain diseases marked by rapidly worsening problems with thinking and movement, the study published in Nature Medicine said. CBD is a rare condition that can cause gradually worsening problems with movement, speech, memory and swallowing, and is one of the tauopathies.
