Development and validation of the DCOS (Digitalised Combined Objective‐Subjective cognitive screening): A five‐minute neuropsychological test for mild neurocognitive disorder

DCOS is a novel screening tool that assesses cognitive impairment from both subjective and objective domains. It presents a potential discriminative performance for mild NCD detection. The brief administration time (<5 minutes) makes it particularly suitable for primary health care. As a next step, DCOS will be incorporated with artificial intelligence and be applied on a digital platform to enhance its utility in large-scale settings.
