Kennedy's disease is an inherited motor neuron disease that affects males. It is one of a group of disorders called spinal muscular atrophy (SMA). Onset of the disease is usually between the ages of 20 and 40, although it has been diagnosed in men from their teens to their 70s. Early symptoms include tremor of the outstretched hands, muscle cramps with exertion, and fasciculations (fleeting muscle twitches visible under the skin). Eventually, individuals develop limb weakness which usually begins in the pelvic or shoulder regions. Weakness of the facial and tongue muscles may occur later in the course of the disease and often leads to dysphagia (difficulty in swallowing), dysarthria (slurring of speech), and recurrent aspiration pneumonia. Some individuals develop gynecomastia (excessive enlargement of male breasts) and low sperm count or infertility. Still others develop non-insulin-dependent diabetes mellitus.
Kennedy's disease is an x-linked recessive disease, which means the patient's mother carries the defective gene on one of her X chromosomes. 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. Parents with concerns about their children may wish to talk to a genetic counselor.
Is there any treatment?
Currently there is no known cure for Kennedy's disease. Treatment is symptomatic and supportive. Physical therapy and rehabilitation to slow muscle weakness and atrophy may prove helpful.
What is the prognosis?
Kennedy's disease is slowly progressive. Individuals tend to remain ambulatory until late in the disease, although some may be wheelchair-bound during later stages. The life span of individuals with Kennedy's disease is usually normal.
What research is being done?
The NINDS supports a broad spectrum of research on motor neuron diseases, such as Kennedy's disease. Much of this research is aimed at increasing scientific understanding of these diseases and, ultimately, finding ways to prevent, treat, and cure them.

I'd never heard of Kennedy's Disease until you posted so I did a search.
I got this from the website below:
"Kennedy's Disease (also known as Spinal Bulbar Muscular Atrophy, SBMA, or Kennedy's Syndrome) is a rare and currently incurable and non-treatable X-linked recessive genetic progressive neuro-muscular disease. Both the spinal and bulbar neurons are affected causing muscle weakness and wasting (atrophy) throughout the body which is most noticeable in the extremities (legs/arms), it is especially noticeable in the face and throat, and causes speech and swallowing difficulties, major muscle cramps as well as other symptoms.
KD is an adult-onset disease with symptoms usually appearing between the ages of 30 and 50. However, earlier onsets have been recorded.
Generally males with this inherited gene develop symptoms, while females with this gene are usually just carriers. Although, in rare cases, females have been known to exhibit symptoms as well. Life expectancy is noted to be at or almost normal."
