Parkinson’s disease: the deep brain stimulation revolution

In the 1990s, Professor Alem-Louis Benapade, a neurosurgeon in Grenoble (Isère), discovered that deep brain stimulation of a region of the brain, the hypothalamic nucleus, has a significant therapeutic effect against the symptoms of Parkinson’s disease. Since then, more than 100,000 patients have been treated in this way all over the world, with significant improvement in their agitation, tremors, rigidity, and slowness of movement.
