Axis 2, which focuses on the non-motor symptoms of Parkinson’s disease, is managed by Jean-François Gagnon and Ron Postuma. Several databases define the infrastructure associated with this axis: clinical, neuroimaging, sleep and neuropsychological.
This second axis focuses on specific types of non-motor symptoms of Parkinson’s disease. Thus, cognitive, psychiatric and sleep disorders will be specifically studied. The excellence of several Quebec research groups in the “Paradoxical Sleep Behavior Disorders” field, particularly in neurodegenerative pathologies, is a remarkable contribution.
Other sleep disorders associated with Parkinson’s disease are also the subject of recent investigations, such as sleep apnea.
Another essential aspect of this axis is the study and understanding of the origins of cognitive and behavioural disorders in the context of the evolution of the disease. Also, developing tools to predict the onset of dementia through neuroimaging will be a central point of investigation.
