Excessive Daytime Sleepiness in Parkinson's Disease and Parkinsonism.

Shifting away from the traditional perspective on parkisonism, which focused only on the motor state of the patients, recent research proves the importance of early recognition and treatment of non-motor symptoms. Patients with parkinsonism, who suffer from various sleep disturbances, such as excessive daytime sleepiness (EDS), experience lower quality of life, a negative impact on activities of daily living, and possible exposure to life-threatening situations. Implementing the routine use of subjective and objective means of diagnosing EDS, into clinical practice, allows for a personalised management plan, in scope of efficiently decreasing disease burden for both the patient and the caregiver.
