Peripheral neuropathic pain in idiopathic Parkinson's disease: Prevalence and impact on quality of life; a case controlled study.

Background And Purpose: Pain is a frequent and debilitating non-motor symptom of Idiopathic Parkinson's Disease (IPD). The present study investigated the prevalence of pain and specifically peripheral neuropathic pain (PNP) in IPD, and ascertained any impact of PNP on quality of life (QoL).

Methods: Patients with IPD and age- and gender-matched controls were screened for overall pain using the King's Parkinson's Pain Scale (KPPS).

Sensory neuropathic symptoms in idiopathic Parkinson's disease: prevalence and impact on quality of life.

Background: Neuropathic symptoms are commonly reported in Parkinson's disease (PD), but robust data on the epidemiology of such symptoms are lacking. The present study sought to investigate the prevalence and determinants of peripheral sensory neuropathic symptoms (PSNS) in idiopathic PD (IPD) and ascertain the effects of such symptoms on the patients' quality of life (QoL).

Methods: Patients with IPD and age-matched and gender-matched controls were screened for neuropathic symptoms using the Michigan Neuropathy Screening Instrument.
