Etude de l'implication du noyau subthalamique dans les troubles sommeil/éveil dans la maladie de Parkinson (description en anglais)

Objectifs

In this study, we aim to characterize the sleep/wake disturbances in Parkinson’s disease and the involvement of subthalamic nucleus in this behavior.

Résumé

Sleep, initially defined as a passive state, has in fact, a major role in a large number of biological phenomena such as the elimination of toxic substances and metabolic waste from the brain by the glymphatic system (Xie et al., 2013). Interestingly, it has been shown that these neurodegenerative diseases are strongly associated with a poor quality of sleep (Abbott & Videnovic, 2016). Sleep is highly modified in Parkinson's disease, but this has only been partially described. In addition, the subthalamic nucleus, which is a common target for deep brain stimulation, appears to play an important role in sleep behavior, but has not been fully studied. This study aims to characterize sleep/wake disturbances in Parkinson's disease. It will also enable us to monitor the activity of the subthalamic nucleus during wakefulness and sleep onset.

Méthodes

This study is preliminary to a clinical trial that will involve the neurology, neurosurgery and sleep laboratory departments of Grenoble University Hospital. The study will be based on data collected before, during and after implantation surgery. The student will have analyzed patients' clinical data, and their sleep scoring in the pre-implantation phase. In addition, the student will be asked to analyze the activity of the subtahlamic nucleus for patients implanted during the period of their internship.
