Neuropathy has been described in significantly higher proportion of PD patients than in control subjects. This study ascertains the prevelance of neuropathy and its determinants in PD patients, in particular relation with nutritional status, along with impact of neuropathy on Quality of life. Methods: This was a hospital based observational cross-sectional study of PD patients attending the Neurology OPD of a tertiary care hospital. The prevalence and type of neuropathy was determined using the validated MNSI scale. The nutritional status was assessed using MNA score and PDQ-39 was used for assessing quality of life. Patients with and without neuropathy were compared to ascertain risk factors for neuropathy. Results: Twenty-four out of 93 PD patients (26%) had neuropathy and 12 (50%) out of them had painful neuropathy. Older patents and those who had longer duration of disease had higher prevalence of neuropathy. In addition there was significant correlation with malnutrition and neuropathy. 79% of patients with neuropathy had abnormal nutritional status. On comparison of patients with painful neuropathy as compared to those without pain, Vitamin B 12 levels were found to be low only in the former group. Conclusions: Our study shows that there is significant prevalence of neuropathy in PD patents that affects the quality of life of PD patients. Neuropathy in PD is disease dependent and is precipitated by malnutrition. Hence, neuropathy must be timely diagnosed and effective nutritional management may help to improve the patient's quality of life.
