Objective: To assess the prevalence of Axis-1 DSM-4 [The Diagnostic and Statistical Manual of Mental disorders] psychiatric disorders in patients with Parkinson’s disease [PD], atypical parkinsonism [P+] and vascular parkinsonism [VascP] in a rural movement disorders clinic using a short structured questionnaire [Mini International Neuropsychiatric Interview (MINI)].

Background: Prevalence of psychiatric co-morbidity in patients with parkinsonism in rural India is not known.

Method: A cross sectional survey of patients attending movement disorders clinic of Shree Krishna Hospital, a rural medical teaching hospital in Karamsad, Gujarat, in Western India was done between Sept 2016 to Feb 2017. 130 consecutive consenting adults with parkinsonism [PD/ P+/ VascP] were assessed using MINI for prevalence of Axis-1 DSM-4 disorders.

Results: Out of 70 patients with PD [ mean age 69,40 males],  42(60%) had depression/dysthymia as compared to 16 out of 34( 47%) patients with P+[mean age 71, 20 males] and 10 out of 26( 38%) of patients with VascP[mean age 73,18 males]. Anxiety was seen in 26(37%) of PD patients, 10 patients (29%)with P+ and 5(19%) patients with VascP. 12(20%) patients with PD had psychosis and 7(10%) had Obsessive compulsive disorder (OCD). 3 (10%) patient with P+ had psychosis and 1 had OCD. No VascP patient had psychosis or OCD. Of 130 patients 81(62%) had co-existent psychiatric co-morbidity [70% in PD, 55% in P+ and 46% in VascP].

Conclusion: Using MINI in clinics can help identify psychiatric comorbidity in patients with parkinsonism. More than half of patients with parkinsonism have comorbid psychiatric disorder
