What is bulbar weakness?
Bulbar weakness (or bulbar palsy) refers to bilateral impairment of function of the lower cranial nerves IX, X, XI and XII, which occurs due to lower motor neuron lesion either at nuclear or fascicular level in the medulla or from bilateral lesions of the lower cranial nerves outside the brain-stem.
Is Addison's disease life threatening?
Addison's disease occurs in all age groups and both sexes, and can be life-threatening. Treatment involves taking hormones to replace those that are missing.
Is Addison's disease fatal?
People with Addison's disease must be constantly aware of the risk of a sudden worsening of symptoms, called an adrenal crisis. This can happen when the levels of cortisol in your body fall significantly. An adrenal crisis is a medical emergency. If left untreated, it can be fatal.
What autoimmune disease causes high cortisol levels?
Addison's disease is caused by an autoimmune response, which occurs when the body's immune system (which protects it from infection) assaults its own organs and tissues. With Addison's disease, the immune system attacks the outer portion of the adrenal glands (the cortex), where cortisol and aldosterone are made.

What is Kennedy disease?
Summary. Kennedy disease is a rare, X-linked slowly progressive neuromuscular 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, ...
How many people have Kennedy disease?
Kennedy disease affects fewer than 1 in 350,000 male s 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%) ...
Is Kennedy disease a genetic disorder?
Kennedy disease is an X-linked genetic disorder that occurs primarily in males. Very rarely, female carriers of the abnormal gene may show symptoms.
What is the treatment for Kennedy disease?
Treatment may include physiotherapy and rehabilitation; medications to alleviate tremor and muscle cramps; and hormone therapy or surgical treatment for gynecomastia. [1] [2]
What is Kennedy disease?
Kennedy disease is a gradually progressive, neuromuscular disorder characterized by wasting of the proximal muscles (those closer to the trunk) and bulbar muscles (those of the face and throat). The condition mainly affects males, with onset between the ages of 30 and 60. [1] Early symptoms may include tremor, muscle cramps, and muscle twitching. This is followed by progressive muscle weakness and wasting, which may manifest in a variety of ways. [1] [2] Affected people may also have gynecomastia, testicular atrophy (reduction in size or function of the testes ), and reduced fertility as a result of mild androgen insensitivity. [2] Kennedy disease is caused by a mutation in the androgen receptor ( AR) gene and is inherited in an X-linked recessive manner. Treatment may include physiotherapy and rehabilitation; medications to alleviate tremor and muscle cramps; and hormone therapy or surgical treatment for gynecomastia. [1] [2]
Why is it important to monitor the progression of Kennedy disease?
The severity and progression of Kennedy disease should be monitored. Because it is slowly progressive, it is important to periodically assess strength and tolerance to exertion. This allows for proactive management to minimize the risk for falls, optimize mobility, and provide appropriate assistive devices. [4]
Is there a cure for Kennedy's disease?
There is currently no cure for Kennedy disease. Treatment aims to relieve symptoms, maintain maximal function, and improve quality of life. Physical therapy and rehabilitation, including the use of braces and walkers, are the best chance for remaining ambulatory as the disease progresses.
Can you have breast reduction surgery with Kennedy disease?
Some people with Kennedy disease have breast reduction surgery for gynecomastia. [2] . The use of anti-androgens have been shown to improve some aspects of the disease is some people; the androgen-dependent nature of the disease is the rationale for the use of anti-androgens in treating Kennedy disease. [4]
What is the cause of Kennedy's disease?
Kennedy disease or spinal and bulbar muscular atrophy is caused by a change (mutation) in the AR gene that encodes for a protein known as the androgen receptor on the X chromosome.
How many CAG repeats are there in the Kennedy disease gene?
An unaffected individual has 10-35 CAG repeats in the AR gene while a person with Kennedy disease has more than 36 CAG repeats in the gene. The androgen receptor is in the cytoplasm of a cell where it responds to signals from male sex hormones (androgens).
What is the X-linked recessive disease?
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.
Can anti-androgen therapy be used for Kennedy's disease?
Hence, the utility of anti-androgen therapy as a treatment for Kennedy’s disease remains unclear. Furthermore, it is possible that anti-androgen therapies, even if effective, would need to be administered prior to disease onset or early on in the neurodegenerative process. More importantly, the side effects of anti-androgen therapies would probably far outweigh the therapeutic benefit for most individuals, and likely should be reserved for people with Kennedy’s disease who are wheelchair bound or exhibit pronounced bulbar weakness.
Is Kennedy disease a genetic disorder?
Kennedy disease is an X-linked genetic disorder that occurs primarily in males. Very rarely, female carriers of the abnormal gene may show symptoms.
Is Kennedy's disease normal?
Kennedy’s disease life expectancy is normal, though a small percentage of patients (about 10%) succumb to the disease in their 60’s or 70’s due to swallowing complications (aspiration pneumonia, asphyxiation) resulting from the bulbar weakness.

What is the diagnosis of Kennedy's disease?
Where to get help. Kennedy's disease is a rare inherited neuromuscular disorder that causes progressive weakening and wasting of the muscles, particularly the arms and legs. Other major symptoms include severe cramps and problems with speech and swallowing.
How many chromosomes do boys have in Kennedy's disease?
This is because boys only receive one X chromosome and, if that has the mutated gene, they will one day develop the symptoms of Kennedy's disease.
How does Kennedy's disease affect the brain?
Kennedy’s disease destroys motor nerves. The brain controls the movement of muscles with nerves. The command to move travels from the upper motor neurons on the brain's surface, down through the spinal cord and into the lower motor neurons.
What test can be used to check for Kennedy's disease?
Genetic tests using a blood sample – this test can check whether the Kennedy's disease gene is present, even if the person is asymptomatic or a carrier. Genetic counselling is important.
Is there a cure for a symtom?
There is no cure yet, and treatment can only ease some of the symptoms. In most cases, females who inherit the gene are carriers, while men who inherit the gene develop the symptoms. (Rarely, an affected woman may develop symptoms too.)
Is Kennedy's disease a neuron?
Since Kennedy's disease is rare, it can be misdiagnosed. It is sometimes mistaken for the more common motor neurone disease (am yotrophic lateral sclerosis), a progressive nervous system disease characterised by the breaking down of neurones in the spinal cord and brain.
What are the symptoms of Kennedy's disease?
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 a cure for Kennedy's disease?
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.
