Outline of Final Research Achievements

Parkinson’s disease is a progressive degenerative CNS disorder to cause a typical motor symptoms. Respiratory alterations have been supposed to follow postural changes and osteoarticular degeneration, leading to an alteration in the spinal axis that in turn could affect breathing mechanics. We examined respiratory movements by using cineradiography on a model of mild hemi-Parkinson disease by an injection of 6-OHDA solution to the right striatum of mice (C57BL/6J), and were compared to control mice that were injected with saline solution. Two weeks after surgery, respiratory movements were recorded by video X-ray without restraint. Behavioral tests confirmed mild motor impairments in Parkinson mice. Parameters of respiratory function showed mild alterations in the Parkinson mice, suggestive of a restrictive-type respiratory disorder. Data suggest that respiratory alterations in Parkinson disease may emerge simultaneously to motor symptoms, and not as a consequence of the latter.
