Abstract
Parkinson's disease is the fastest growing neurological condition in the world with no cure; therefore, choosing the correct treatment to manage the patient's symptoms and prolonging their quality of life is of the utmost importance. Deep brain stimulation, an established methodology involving continuous electrical stimulation to the brain through surgically implanted electrodes, can present an effective option, but careful patient selection is needed to optimise outcomes. Here, Francesca Ramadan presents an overview of the current impact of deep brain stimulation and the ways in which its potential might be maximised in the future.
