Objective: Aim of this study was to evaluate frequency and characteristics of sleep disorders among patients with Parkinson disease (PD), cervical dystonia (CD) and depression.

Background: Sleep disorders are among most common non motor symptoms in patients with Parkinson`s disease, but also in patients with depression and cervical dystonia.

Methods: We have evaluate 122 patients (30 control, 32 Parkinson disease, 30 cervical dystonia and 30 depressed). Demographic data were collected. All of them, except depressed group, were tested for depression and anxyety using Beck Depression Inventory (BDI) and Beck Anxyety Inventory (BAI). To evaluate sleep disorders we used Pittsburg Sleep Questionaire (PSQI) and Epwort Sleep Scale (ESS).

Results: All three groups of the patients differ in PSQI score and all PSQI subscales except of feeling hot in respect to control healthy group. Depression group differ in most subscales of PSQI, than PD and last CD group. Also, depression group had worst results for most scales in respect to PD and CD, while PD and CD differ only in 2 subscales each. Only PD group had worse results for ESS score, sleeping after lunch and in public place in respect to control and CD while for seating in public to depressed group.

Conclusions: When compare to healthy control, PD, CD and depression group had more sleep disorders. Among them patients with depression had the most impaired sleep. PD and CD group do not differ significanlty in sleep disorders during the night, while only PD patients experiance daily sleeping problems.
