Neurological Sciences [2013] Nov 7 [Epub ahead of print]
Researchers assessed the prevalence of headache in people with Parkinson's Disease and the association between the side of Parkinon's Disease symptom onset and the side of their headache. Headaches were found to occur significantly less in people with Parkinson's Disease, 40% of whom had headaches, than in people who do not have Parkinson's Disease, 70% of whom had headaches. The prevalence of headaches being significantly lower in people with Parkinon's Disease is unexplained by the researchers.
Fewer people with Parkinson's Disease (74%) had headaches throughout life in contrast to the 94% of people who had headaches throughout life who did not have Parkinson's Disease. Considering only people who had headaches during the previous year, people with Parkinson's Disease had a higher association with migraine rather than tension headaches compared to people who did not have Parkinson's Disease. The headache side in people with Parkinson's Disease was also on the same side as the side of Parkinson's Disease onset in 84 % of people.
