When do difficulties with cognition or mental health cross the threshold from ordinary to something that needs medical attention? In the context of limited resources, objective testing is invaluable. But because highly trained specialists are few and far between, NHS health workers are often the ones responsible for the essential task of assessing patients’ cognition and mood. In answer to this burden, MRC CBU researcher Tom Manly – together with colleagues in Oxford and the NHS – developed a helpful tool, a touchscreen app called OCS-BRIDGE. The app guides health workers through a range of tests, automatically captures and scores patient responses, and immediately returns a clinical report on language, memory, perception, attention, and mood. As OCS-BRIDGE is also highly portable and cost-effective, it is already streamlining care in the NHS and contributing to medical research throughout the UK.
