Research summary
Patients referred to our department routinely and safely undergo deep brain stimulation (DBS) for treatment of symptoms related to neurodegenerative conditions, most commonly Parkinson’s disease.
In patients undergoing therapeutic DBS for a particular subtype of Parkinsonism (Multiple System Atrophy), the effects on autonomic parameters such as blood pressure and bladder symptoms has been shown to be improved by our group (unpublished data). In this current study, we plan to use a novel technique of adaptive DBS in order to provide stimulation dependent on patient physiological or positional factors. This will make stimulation more responsive and patient specific.
Our key goal is to:
Prove that a patient and physiology-specific DBS system that can adapt to changes in the patient is able to give at least as good an improvement in quality of life and physiological parameters as standard DBS.
Lay Summary -
Patients referred to our department routinely and safely undergo deep brain stimulation (DBS) for treatment of symptoms related to neurodegenerative conditions, most commonly Parkinson’s disease.In patients undergoing therapeutic DBS for a particular subtype of Parkinsonism (Multiple System Atrophy), the effects on autonomic parameters such as blood pressure and bladder symptoms has been shown to be improved by our group (unpublished data). In this current study, we used a novel technique of adaptive DBS in order to provide precise control of stimulation based on factors such as position, movement and the day-night cycle.
We recruited three patients with Multiple System Atrophy (MSA) in our study, demonstrating that DBS could improve parameters including standing blood pressure and walking speed when measured in a controlled environment, as well as some longer-term symptoms related to the bladder. However, this did not translate to significant improvements in patients' overall quality of life, mainly due to the rapid progression of the disease. Overall, our results suggest that deep brain stimulation, while potentially improving some aspects of the disease, is unlikely to be a beneficial treatment in MSA.
