In this series, ARF takes stock of deep-brain stimulation after more than a decade of life-altering procedures,  In deep brain stimulation, surgeons implant wires into the brain and hook them up to a pacemaker-like stimulator implanted in the chest, which sends electrical signals to his brain that quiet tremors or stimulate dying brain areas. Now is an interesting time to learn more about this treatment, because even as scientists are gathering long-term data on its initial indications—movement disorders—they are beginning to explore whether DBS might also work for a range of other conditions, including Alzheimer’s.
