CHRONIC PAIN IN PARKINSON'S DISEASE
Mvement Disorders [2008] Jun 10; [Epub ahead of print] (Negre-Pages L,

Pain is a frequent, but poorly studied symptom of Parkinson's Disease. This
survey aimed to assess the prevalence of chronic pain in Parkinson's
Disease, to describe Parkinson's Disease patients with chronic pain, and to
record analgesic consumption. 62% of people with Parkinson's Disease were
found to suffer from chronic pain. 26% of people with Parkinson's Disease
had pain unrelated to Parkinson's Disease ("non-PD-pain", caused mainly by
osteoarthritis), while 39% had chronic pain related to Parkinson's Disease
("PD-pain"). In this last group, Parkinson's Disease was the sole cause of
pain in the majority, whilst the others suffered from indirectly aggravated
pain of another origin, which was mainly osteoarthritis. Parkinsonian
patients with "PD-pain" were younger at Parkinson's Disease onset, had more
motor complications, more severe depressive symptoms than those without pain
or with "non-PD pain." "PD-pain" was more intense, but was less frequently
reported to doctors, and was associated with less frequent analgesic
consumption than "non-PD-pain." Pain was twice more frequent in Parkinson's
Disease patients than in patients without Parkinson's Disease. Chronic pain
is frequent but underreported in Parkinson's Disease.
