A Monitoring System for the Recognition of Sleeping Disorders in Patients with Cognitive Impairment Disease

Alzheimer’s disease (AD) is the most common type of dementia; accounts report the impact of AD in a range of 60–80 % with respect all the dementia related pathologies. Patients with Alzheimer’s could show early symptoms such as sleep disturbances, well-formed visual hallucinations, and muscle rigidity or other AD movements disorders. In this work we focus on disturbances related to sleep disorders, for this reason, we propose a monitoring system for the recognition of these kind of disorders. In detail, we present: (1) a novel model for the detection of a particular type of sleep disorders, the Periodical Legs Movements (PLM) and (2) a prototype of monitoring system able to recognize the PLM events. Preliminary experiment have been made by monitoring a patient with a early stage of the sleep disorder.
