Scientists say automated adjustment of levels could halve duration of most troublesome symptoms
A fresh approach to brain stimulation could offer people living with Parkinson’s better control over their symptoms and halve the duration of those that trouble them most, experts have said.
At present, this stimulation is set at a constant level regardless of what the patient is doing, or the severity of their symptoms. As a result the technique can result in either understimulation, resulting in a breakthrough of symptoms, or overstimulation, leading to erratic movements. “This device can sense brain activity and provide stimulation at the same time. Our job was to create the algorithms for the software that runs on this device,” said Oehrn.
The team tailored the algorithms to each individual and their most bothersome symptom, resulting in a system whereby participants’ brain signals were continuously monitored and the electrical stimulation automatically adjusted in response to their needs.
