Alan Jackson has been dealing with a long‑term health issue rather than a sudden new illness: he has Charcot‑Marie‑Tooth (CMT) disease , a degenerative nerve condition that affects his muscles, balance, and mobility.

What the condition is

  • Charcot‑Marie‑Tooth disease is a hereditary neuropathy that damages nerves in the arms and legs, leading to muscle weakness, reduced sensation, and trouble with coordination.
  • Jackson has said he inherited it from his father and that there is no cure , though symptoms can be managed.

How it affects him

  • The disease has made it harder for him to walk and stand steadily , which is why fans have noticed him seeming unsteady or using support on stage.
  • He has been open about stumbling around during performances and has said the condition has been affecting his ability to tour comfortably for more than a decade.

Recent updates and public appearances

  • In 2021, Jackson publicly discussed CMT during a “Today” show interview, calling it a “neuropathy and neurological disease” he’s been living with for years.
  • As of 2025–2026 , he has continued to make appearances (including the Academy of Country Music Awards and his planned final concert in June 2026 in Nashville), but he has framed his reduced touring as partly due to this progressive condition.

What “what is wrong with Alan Jackson” really means

  • Fans asking “what is wrong with Alan Jackson” are usually reacting to his visible physical changes —his slower gait, need for support, or quieter stage presence—but there is no indication of a new, separate serious illness beyond his ongoing CMT.
  • He has not publicly disclosed any other major diagnoses, so current health discussions center on his long‑term CMT journey and how it shapes his final performances and retirement from touring.
