Research

  • Parkinson’s disease exhibits considerable heterogeneity in clinical presentation and progression. This suggests potent neuroprotective and compensatory mechanisms, which could possibly serve for disease-modifying therapies, as well as the care of parkinsonian patients. To this regards, we have a strong neurobiological interest and focus on the contribution of the noradrenergic system to the pathology of Parkinson’s disease. 

 

  • The annual incidence of falls amongst patients with Parkinson’s disease is up to 60% and may lead to injuries, loss of independence, institutionalization and increased mortality. Currently, no treatment is particularly efficient and fall prediction and prevention remain elusive. Our research combines molecular brain imaging studies with simultaneous biomechanical measurements and cortical and deep brain recordings to elucidate posture and locomotion disturbances in parkinsonian patients.

 

  • Levodopa-related dyskinesias are unintended, involuntary and uncontrollable movements that emerge in the vast majority of parkinsonian patients and can interfere dramatically with patients’ life. We are investigating the molecular and neurophysiological mechanisms of dyskinesias with multiple molecular imaging studies and neurophysiological recordings (e.g., navigated transcranial magnetic stimulation combined with high-density electroencephalography).
