Is there a cure for Kennedy's disease?
Kennedy's disease is also known as X-linked spinal bulbar muscular atrophy (SBMA). There is no cure yet, and treatment can only ease some of the symptoms.
Is anti-androgen therapy an effective treatment 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.
What is Kennedy's disease?
Kennedy's disease is an inherited motor neuron disease that affects males. It is one of a group of disorders called lower motor neuron disorders (which involve disruptions in the transmission of nerve cell signals in the brain to nerve cells in the brain stem and spinal cord).
How can genetic counselling help with Kennedy's disease?
Genetic counselling is important. There is no cure for Kennedy's disease, because medical science doesn't know how to regenerate muscle neurones. Treatment aims to ease some of the symptoms and can include:
Can Kennedy's disease be cured?
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. Kennedy's disease is slowly progressive.
How long can you live with Kennedy's disease?
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. The disease progresses slowly, and life expectancy is usually normal.
Is Kennedy's disease fatal?
This means life expectancy with Kennedy's disease is normal. Men are usually affected. It is very rare for women to develop symptoms, but they can pass it on to their sons or daughters.
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.
Can bulbar palsy be cured?
As there is no cure for Bulbar Palsy, treatment is essentially limited to medical management and support. For patients presenting with Bulbar Palsy, treatment will be directed to the underlying cause of the syndrome. Medication may include intravenous immunoglobulin (antibody) and steroids.
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.
What is the life expectancy of someone with SMA?
The life expectancy of patients with spinal muscular atrophy (SMA) type I is generally considered to be less than 2 years. Recently, with the introduction of proactive treatments, a longer survival and an improved survival rate have been reported.
Is Kennedy's disease ALS?
Diagnosis of the Condition Often, individuals with Kennedy disease are mistakenly thought to have amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease). However, ALS, as well as the other similar disorders, does not include endocrine disorders or loss of sensation.
Which muscles are bulbar muscles?
It's also sometimes called bulbospinal muscular atrophy. The adjective bulbar refers to a bulblike structure in the lower part of the brain that contains nerve cells controlling muscles in the face, mouth and throat.
How rare is Kennedy's disease?
Kennedy disease affects approximately 1/40,000 people worldwide and is very rare in females.
What are bulbar signs?
Bulbar palsy symptoms Tongue - weak and wasted and sits in the mouth with fasciculations. Drooling - as saliva collects in the mouth and the patient is unable to swallow (dysphagia). Absent palatal movements. Dysphonia - a rasping tone due to vocal cord paralysis; a nasal tone if bilateral palatal paralysis.
What genetic disease did Kennedy have?
President Kennedy's Addison's disease, which came to light only after his election in 1960, was most likely caused by a rare autoimmune disease, according to a Navy doctor who reviewed Kennedy's medical records.
What is Kennedy's disease?
Kennedy's Disease is a rare 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, ...

Is there a cure for KD?
Unfortunately, there is no know treatment or cure, but researchers continue to make strides every year. Some individuals living with KD do take medications prescribed by their medical doctor to help alleviate various symptoms. Others have reported that a smart (light) exercise program coupled with stretching helps.
What is the treatment for Kennedy's disease?
Currently, there is no known treatment or cure for Kennedy disease. Physical therapy, occupational therapy , and speech therapy are commonly used to adapt to the progressing disease and maintain an individual’s skills. Braces, walkers, and wheel chairs are used for ambulation.
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 male or female?
Kennedy disease is an X-linked genetic disorder that occurs primarily in males. Very rarely, female carriers of the abnormal gene may show symptoms. Normal females have two X chromosomes, in which one is an activated chromosome and the other is inactivated.
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.
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.
Is anti-androgen therapy effective?
Anti-androgen therapy. There is no consensus or clear evidence as to whether anti-androgen therapy is an effective form of treatment for the neurologic complications . Anti-androgen therapy shows promise based on studies in Drosophila and mouse models as well as knowledge of the molecular basis of Kennedy’s disease.
Is Kennedy disease a male or female?
Kennedy disease is an X-linked genetic disorder that occurs primarily in males. Very rarely, female carriers of the abnormal gene may show symptoms. Normal females have two X chromosomes, in which one is an activated chromosome and the other is inactivated.
Is Kennedy's disease a sex-limited disorder?
Kennedy’s disease is a sex-limited disorder, with females protected by having low levels of circulating androgens leading to lower levels of androgen receptor stimulation. In addition, due to X-chromosome inactivation, females have only a portion of actively transcribed full-penetrance alleles (CAG>37), but it is the low level of circulating androgen that likely accounts for limited to absent symptoms in heterozygous female carriers or in females with biallelic full-penetrance AR alleles.
What is Kennedy's disease?
Read the full fact sheet. Kennedy's disease is a rare inherited neuromuscular disorder that causes progressive weakening and wasting of the muscles, particularly the arms and legs. Kennedy's disease is caused by a genetic mutation of the androgen receptor gene on the X chromosome. There is no cure, and treatment can only ease some ...
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.
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 Kennedy's disease progressive?
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 is Kennedy's disease?
Kennedy’s disease, or bulbospinal muscular atrophy (BSMA), is an untreatable motor disorder characterized by slowly progressive weakness and atrophy (muscle wasting) affecting the facial and limb muscles as well as the muscles involved in swallowing.
Is Kennedy's disease a recessive disorder?
Kennedy’s disease is an X-linked recessive disorder ; as such, men (XY) with the gene are affected though women (XX). Women carrying only one copy of the gene rarely have the symptoms.
Is Kennedy's disease the same as Lou Gehrig's disease?
Kennedy’s disease is a form of motor neuron disease, and therefore may appear clinically similar to amyotrophic lateral sclerosis (ALS / Lou Gehrig’s disease). 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.
