Carl Cannon is at his best when he's helping others be their best. Throughout his life, he's helped others realize their potential as he realized his. The one thing that threatened to diminish that potential was a tremor. Essential tremor, a neurological disorder that causes involuntary shaking, can affect almost any part of the body. Cannon experienced tremors, perhaps the worst in his hands, for the better part of two decades. Still, as he guided members of his community to a better path, he knew he had to find one for himself. That's when Cannon met deep brain stimulation (DBS) — which uses a pacemaker-like device to send targeted signals to a specific area of the brain to relieve tremor. 'It's incredible when you see a light go on in someone.' Cannon was referring to how he betters the lives of people in his community, but he could easily be talking about himself.
