Monitoring system for monitoring a patient and detecting delirium of the patient

A processor for use in an automated monitoring system for monitoring a patient, said processor comprising:

• a first processing unit for detecting motion events of the patient from image data obtained over time from the patient,
• a second processing unit for classifying the detected motion events into delirium-typical motion events and non-delirium-typical motion events and for determining high or low movement counts of detected motion events, and
• a third processing unit for determining a delirium score from the duration of high or low movement counts and/or the duration, intensity, type, location and/or occurrence of delirium-typical motion events, said delirium score indicating the likelihood and/or strength of delirium of the patient.
