A portable autonomous multisensory intervention device (PAMID) for early detection of anxiety and agitation in patients with cognitive impairments

The negative behavioral and psychological symptoms (NBPS) seen in patients with cognitive impairment (CI), such as anxiety, agitation and aggression have been reported to be the most problematic for healthcare providers. The consequences of delayed detection of NBPS can be devastating for both patients and caregivers; therefore early detection of symptoms that may lead into NBPS is essential. A proprietary device called portable autonomous multisensory intervention device (PAMID) has been developed to not only wirelessly monitor physiological conditions as a means for early detection of NBPS, but also automatically provide a real-time multisensory intervention to reduce NBPS in patients with CI if thresholds of physiological parameters reflecting the symptoms are detected. This paper outlines the enhancement of PAMID and test results from a pilot study. This device to be developed will have significant applications in the emerging Tele-healthcare systems.
