Adrenomyeloneuropathy is a rare genetic disease that is a form of adrenoleukodystrophy. The disease affects the nerve cells in the spine and possibly the brain and the adrenal glands. The first symptoms are often trouble walking. Adrenomyeloneuropathy most often occurs in young men (20 to 40 years) but may begin anywhere between the ages of 20 and 50 years. Women may also be affected but with later and milder symptoms, or may be carriers of the disease, meaning that they do not show symptoms but can pass the genetic trait to their children. The disease has two main types: adrenomyeloneuropathy with cerebral involvement (both the spinal cord and brain are affected), and adrenomyeloneuropathy without cerebral involvement (only the spinal cord is affected).
