Machine Learning to Identify Psychomotor Behaviors of Delirium for Patients in Long-Term Care Facility

DELIRIUM is a typical geriatric syndrome that causes psychotic symptoms and cognitive function disorders (such as impaired consciousness, attention, and speech) that occur suddenly due to various causes. Delirium is linked to confusion, hallucinations, delusions, psychomotor anxiety symptoms, and aggressive behavior, in addition to impaired attention and speech. Despite overwhelming evidence for the clinical importance of recognizing and preventing delirium, the syndrome remains under-detected by clinicians. In general, four psychomotor behavior subtypes of delirium are recognized: normal, hypoactive, hyperactive, and mixed.
