Tyrone Nanton was a commercial airline pilot by day and an artist by night. Until one day a tremor got progressively worse and made his hands shake so much that it kept him from not only his artistic passion, but also flying. Tyrone saw a Mayo Clinic movement disorders specialist and neurologist Dr. Ryan Uitti, who confirmed he had an essential tumor - a nervous system disorder that causes involuntary and rhythmic shaking. Doctors recommended Tyrone undergo deep brain stimulation (DBS), a procedure that involves implanting electrodes in specific areas of the brain and delivering electric impulses. After two DBS operations, Tyrone was cleared to fly again for the first time in 10 years.
