Among the hundreds of thousands of people diagnosed with Parkinson’s disease, the use of deep brain stimulation can help control tremors and improve motor function. According to a new Canadian study, neurostimulation can have positive effects on disorders of the body’s motor system. Details of the study were recently published online in the Archives of Neurology. Parkinson’s disease is a neurological disorder resulting from degeneration of neurons in the region of the brain that controls movement. As the disease progresses, the degeneration leads to a shortage of the brain’s neurotransmitting chemical known as dopamine, which promotes a lack of brain signals that cause the movement impairments associated with the disease.
