Alan Jackson, the American country singer and songwriter, has been diagnosed with Charcot-Marie-Tooth (CMT) disease, a group of disorders that cause nerve damage. He inherited the disease from his father, and it has affected several members of his family. Jackson was diagnosed with CMT 10 years ago, but the symptoms have recently started to affect his ability to move and maintain balance on stage.
CMT is an incurable degenerative neurological disease. Despite his diagnosis, Jackson continues to perform to the best of his abilities and wishes to sing and tour more. The disease has been affecting him for years, and its progression is becoming more and more obvious.
