Background: Parkinson disease (PD) is also a major chronic disease, and its clinical significance is increasing worldwide. The present study was conducted to assess association between glycemic status and clinical stage of PD. Materials & Methods: 89 patients of Parkinson disease (PD) of both genders were included. Sleep quality was assessed using Parkinson’s disease sleep scale (PDSS). Presence of depression was assessed using Hamilton Depression (HAM-D) Rating Scale. Presence of motor and autonomic symptoms were recorded. Results: out of 89, males were 49 and females were 40. Autonomic dysfunction was constipation in 42, urinary symptoms in 34, sexual dysfunction in 28 and postural giddiness in 53 patients. Non- motor symptoms was sleep disorder in 23, depression in 38, pain in 21, olfactory dysfunction in 45 and cognitive dysfunction in 61. Glycated hemoglobin <5.7% was seen in 18, 5.7- 6.4 % in 23 and >6.5% in 48. The difference was significant (P< 0.05).Conclusion: Poor glycemic control was found in most of patients with PD.
