Abstract:
Objective To assess the sleep disturbance in patients with early-stage idiopathic Parkinson's disease of different clinical subgroups. Methods Four hundred and eighty-six Chinese PD patients were selected as our subjects. Their clinical data including demographics,a broad spectrum of motor variables and non motor features,including tremor,rigidity,hypokinesia,PIGD,motor phenotypes,disease progression,fatigue, constipation,apathy,depression,global cognitive function and L-dopa complications were collected and analyzed by cluster analysis. The PD subtypes were classified by using k-means cluster analysis according to the clinical data. The cluster analysis indicated four main subtypes:subtype 1 was mildly affected in all domains;subtype 2 was severely affected on all motor and non motor symptoms;subtype 3 showed intermediate severity in most domains;subtype 4 characterized by short disease duration and rapid disease progression. Then compared the sleep disturbance among different subtypes with Pittsburgh Sleep Quality Index( PSQI). Results Two hundred and thirty-six cases(48. 6%)were identified as suffering from sleep disturbance. Of which,female PD with sleep disturbance rate was 55. 1%( 130/236 )and male was 44. 9%( 106/236 ). Female was prone to develop sleep disturbance at early stage than male. PSQI scores in subtype 1,2,3 and 4 were(6. 09 ± 3. 72),(9. 36 ± 4. 24), (7. 82 ±4. 35)and(9. 09 ± 4. 73)respectively and the difference was significant(F =14. 503,P =0. 000) . Conclusion Sleep disturbance occurs frequently in patients with early-stage Parkinson's disease and exist clinical heterogeneity.
