- swallowing difficulties.
- speech difficulties.
- hand tremors.
- shaky muscles when holding certain postures.
- muscle weakness.
- muscle wastage.
- muscle twitches.
- muscle cramps and spasms.
Why is it called Kennedy’s disease?
Kennedy disease is named after William R. Kennedy, MD, who described this condition in an abstract in 1966 and a full report in 1968.
What is the difference between Kennedy’s disease and ALS?
A key feature that distinguishes Kennedy’s disease from ALS is the absence of involvement of upper motor neurons, which causes increased reflexes and spasticity in ALS.
Which muscles are bulbar muscles?
Bulbar signs: bulbar muscles are those supplied by the motor nerves from the brain stem, which control swallowing, speech, and other functions of the throat.
Is Kennedy’s disease MND?
Kennedy’s disease (also known as spinal bulbar muscular atrophy or SBMA) is a rare disorder of the motor neurones, caused by a genetic mutation. The MND Association supports people with or affected by Kennedy’s disease.
What is bulbar myasthenia gravis?
Weakness and fatigue in the neck and jaw also can occur early in MG. This bulbar weakness — named for the nerves that originate from the bulblike part of the brainstem — can cause difficulty with talking (dysarthria), chewing, swallowing (dysphagia), and holding up the head.
What is bulbar atrophy?
Spinal-bulbar muscular atrophy (SBMA) is a genetic disorder in which loss of motor neurons — nerve cells in the spinal cord and brainstem — affects the part of the nervous system that controls voluntary muscle movement.
What is a spinal and bulbar muscular atrophy?
Spinal and bulbar muscular atrophy, or Kennedy’s disease, is an X-linked motor neuron disease caused by polyglutamine repeat expansion in the androgen receptor. The disease is characterised by weakness, atrophy and fasciculations in the limb and bulbar muscles.
What are symptoms of spinal muscular atrophy?

How is Spinal muscular atrophy diagnosed?
Spinal muscular atrophy (SMA) is usually diagnosed through a blood test to check for the presence of the SMN1 gene (genetic testing). This gene is missing in about 95 percent of those with SMN-related SMA. In the other 5 percent, the gene will appear mutated. Your physician will order this test if they suspect that you or your child might have SMA based on symptoms and other diagnostic work-up.
What are the signs of atrophy?
