Who muscular dystrophy affects?
MD is a genetic disorders in which strength and muscle bulk slowly weakens. It is caused by incorrect or missing genetic information. Without this information you can not build or maintain healthy muscles. You slowly lose the ability to walk or even sit up right. This disease can occur at any age in a persons life and there is no known cure.

Is Duchenne muscular dystrophy more likely to occur in males or in females?
idk bro why dont you figuhre it out
What is the percentage of muscular dystrophy in males?
Prevalence of MD is higher in males. In the United States, Duchenne and Becker MD occur in approximately one in 3,300 boys. Overall incidence of MD is about 63 per one million people.
When do symptoms of adult-onset Limb-girdle muscular dystrophy appear?
usually appear in a person's teens or twenties, and are marked by progressive weakness and wasting of the muscles closest to the trunk. Contractures may occur, and the ability to walk is usually lost about 20 years after onset
Muscular dystrophy?
DefinitionDuchenne muscular dystrophy is an inherited disorder that involves rapidly worsening muscle weakness.Alternative NamesPseudohypertrophic muscular dystrophy; Muscular dystrophy - Duchenne typeCauses, incidence, and risk factorsDuchenne muscular dystrophy is a rapidly-worsening form of muscular dystrophy. Other muscular dystrophies (including Becker's muscular dystrophy) get worse much more slowly.Duchenne muscular dystrophy is caused by a defective gene for dystrophin (a protein in the muscles). However, it often occurs in people without a known family history of the condition.Because of the way the disease is inherited, males are more likely to develop symptoms than are women. The sons of females who are carriers of the disease (women with a defective gene but no symptoms themselves) each have a 50% chance of having the disease. The daughters each have a 50% chance of being carriers.Duchenne muscular dystrophy occurs in approximately 1 out of every 3,600 male infants. Because this is an inherited disorder, risks include a family history of Duchenne muscular dystrophy.SymptomsSymptoms usually appear before age 6 and may appear as early as infancy. They may include:FatigueMental retardation (possible, but does not worsen over time)Muscle weakness Begins in the legs and pelvis, but also occurs less severely in the arms, neck, and other areas of the bodyDifficulty with motor skills (running, hopping, jumping)Frequent fallsRapidly worsening weaknessProgressive difficulty walkingAbility to walk may be lost by age 12By age 10, the person may need braces for walking. By age 12, most patients are confined to a wheelchair.Signs and testsA complete nervous system (neurological), heart, lung, and muscle exam may show:Abnormal heart muscle (cardiomyopathy)Congestive heart failure or irregular heart rhythm (arrhythmias) -- rareDeformities of the chest and back (scoliosis)Enlarged calf muscles, which are eventually replaced by fat and connective tissue (pseudohypertrophy)Loss of muscle mass (wasting)Muscle contractures in the heels, legsMuscle deformitiesRespiratory disorders, including pneumonia and aspiration of food or fluid into the lungs (in late stages of the disease)Tests may include:Electromyography (EMG)Genetic testsMuscle biopsySerum CPKTreatmentThere is no known cure for Duchenne muscular dystrophy. Treatment aims to control symptoms to maximize quality of life. Gene therapy may become available in the future.Activity is encouraged. Inactivity (such as bedrest) can worsen the muscle disease. Physical therapy may be helpful to maintain muscle strength and function. Orthopedic appliances (such as braces and wheelchairs) may improve mobility and the ability to care for yourself.Support GroupsYou can ease the stress of illness by joining a support group where members share common experiences and problems. See muscular dystrophy - support group. The Muscular Dystrophy Association is an excellent source of information on this disease.Expectations (prognosis)Duchenne muscular dystrophy leads to quickly worsening disability. Death usually occurs by age 25, typically from lung disorders.ComplicationsCardiomyopathyCongestive heart failure (rare)DeformitiesHeart arrhythmias (rare)Mental impairment (varies, usually minimal)Permanent, progressive disability Decreased mobilityDecreased ability to care for selfPneumonia or other respiratory infectionsRespiratory failureCalling your health care providerCall your health care provider if:Your child has symptoms of Duchenne muscular dystrophySymptoms worsen, or new symptoms develop, particularly fever with cough or breathing difficultiesPreventionGenetic counseling is advised if there is a family history of the disorder. Duchenne muscular dystrophy can be detected with about 95% accuracy by genetic studies performed during pregnancy.ReferencesKliegman RM, Behrman RE, Jenson HB, Stanton BF. Muscular dystrophies.

Facioscapulohumeral muscular dystrophy?
DefinitionFacioscapulohumeral muscular dystrophy is progressive muscle weakness and loss of muscle tissue.See also: Muscular dystrophyAlternative NamesLandouzy-Dejerine muscular dystrophyCauses, incidence, and risk factorsFacioscapulohumeral muscular dystrophy affects the upper body, unlike Duchenne muscular dystrophy and Becker muscular dystrophy, which affect the lower body.Facioscapulohumeral muscular dystrophy is a genetic disorder. It appears in both men and women and may develop in a child if either parent carries the gene for the disorder.Facioscapulohumeral muscular dystrophy affects approximately 5 out of 100,000 people. It affects men and women equally.SymptomsFacioscapulohumeral muscular dystrophy mainly affects the face, shoulder, and upper arm muscles. However, it can affect muscles around the pelvis, hips, and lower leg.Symptoms often do not appear until age 10 - 26, but it is not uncommon for symptoms to appear much later. In some cases, symptoms never develop.Symptoms are usually mild and very slowly become worse. Facial muscle weakness is common, and may include:Eyelid droopingInability to whistleDecreased facial expressionDepressed or angry facial expressionDifficulty pronouncing wordsShoulder muscle weakness causes deformities such as pronounced shoulder blades (scapular winging) and sloping shoulders. The person has difficulty raising the arms because of shoulder and arm muscle weakness.Weakness of the lower legs is possible as the disorder gets worse. The weakness can be severe enough to interfere with walking.Hearing loss and abnormal heart rhythms may occur, but are rare.Signs and testsA physical examination reveals weakness of the facial and shoulder muscles. High blood pressure may be noted but is usually mild. An eye exam may show changes in the blood vessels in the back of the eye.Tests that may be done include:Creatine kinasetest (may be slightly high)Electrocardiogram (EKG)EMG(electromyography)Genetic testing of chromosome 4Hearing testMuscle biopsy(may confirm the diagnosis)TreatmentThere is no known cure for facioscapulohumeral muscular dystrophy. Treatments are given to control symptoms and improve the person's quality of life. Activity is encouraged. Inactivity such as bedrest can make the muscle disease worse. Physical therapy may help maintain muscle strength.Expectations (prognosis)Disability is often minor. Lifespan is usually not affected.ComplicationsDecreased mobilityDecreased ability to care for selfDeformities of the face and shouldersHearing lossVision loss (rare)Calling your health care providerCall for an appointment with your health care provider if symptoms of this condition develop.Genetic counseling is recommended for couples with a family history of this condition who wish to have children.ReferencesKliegman RM, Behrman RE, Jenson HB, Stanton BF. Muscular dystrophies. In: Kliegman RM, Behrman RE, Jenson HB, Stanton BF, eds. Nelson Textbook of Pediatrics. 18th ed. Philadelphia, Pa: Saunders Elsevier; 2007:chap 608.
What is the difference between muscular disorders and skeletal disorders?
Muscular disorders occur in the muscles while skeletal disorders occur in the bones.
When do symptoms of Facioscapulohumeral muscular dystrophy first occur?
most commonly begin in the teens or early twenties, though infant or childhood onset is possible. Symptoms tend to be more severe in those with earlier onset. The disease is named for the regions of the body most severely affected
Can people with hypotonia have Asperger's Syndrome?
Hypotonia is a term describing the condition of decreased muscle tone, also known as floppy infant syndrome. Some people with Asperger's Syndrome or autism have hypotonia. It is common for people with Asperger's Syndrome and autism to have some motor control or muscular difficulties, but not necessarily hypotonia. There are many conditions that can co-occur with hypotonia, such as Down syndrome, muscular dystrophy, and cerebral palsy.
