Kennedy’s Disease, also known as Spinal Bulbar Muscular Atrophy, is a progressive genetic neuro-muscular disease.

The disease begins by attacking both the spinal and bulbar neurons, causing muscle weakness throughout the body. As the disease progresses, the motor neurons begin to die and the muscles will waste away, leaving men physically disabled. What starts with small trips and falls, can eventually lead to wheelchair confinement and full-time care. Due to similarities in symptoms, many patients are initially misdiagnosed with ALS.

Although the disorder predominantly affects males, it is passed on through female carriers of the gene. Daughters of patients with Kennedy's disease are also carriers, and have a 1 in 2 chance of having a son affected with the disease. The disease is passed on 100% from Father to Daughter. Carrier mothers have a 50/50 chance of passing it on to both their sons and daughters.

Kennedy's Disease has no cure or current treatment.
