General Discussion

Summary
Kennedy disease is a rare, X-linked slowly progressive neuro-muscular disorder. Kennedy disease is typically an adult-onset disease, where symptoms occur mainly between the ages of 20 and 50. The disease is characterized by symptoms such as muscle weakness and cramps in the arms, legs, and facial area, enlarged breasts, and difficulty with speaking and swallowing (dysphagia). Kennedy disease affects fewer than 1 in 150,000 males and does not typically occur in females, who are protected by their low levels of circulating testosterone, accounting for the sex-limited inheritance pattern in this disorder. Treatment is symptomatic and supportive and life expectancy is normal, though a small percentage of patients (~ 10%) succumb to the disease in their 60's or 70's.

Introduction
Kennedy disease is named after William R. Kennedy, MD, who described this condition in an abstract in 1966 and a full report in 1968.
