Muscular Dystrophy Canada (MDC) (French : Dystrophie musculaire Canada) is a non-profit organization seeking a cure for neuromuscular disorders. Founded in 1954 as Muscular Dystrophy Association of Canada, volunteers and staff nationwide have helped to provide support and resources to those affected. Since the founding year, over $64 million has been put towards research via collaborations, fundraising events, and donations. [1]
Muscular Dystrophy Canada provides various programs within five areas of service: Education, Information, Advocacy, Support and Equipment.
In 2000, Muscular Dystrophy Canada joined with the ALS Society of Canada and the Canadian Institutes of Health Research in the Neuromuscular Research Partnership (NRP). [2]
In 2011, there were over 38 chapters and two affiliates across Canada. [2]
Muscular Dystrophy Canada was founded in 1954 as the Muscular Dystrophy Association of Canada by Dr. David Green and Arthur Minden along with a number of parents whose children were affected by the disorder. The first President was Arthur Minden. [2] Today Arthur Minden's humanitarian work is remembered by the Arthur Minden Pre-Doctoral Award, set up through Muscular Dystrophy Canada. [3] Fire departments have continued to be Muscular Dystrophy Canada's strongest source of fund-raising support. [2]
Muscular Dystrophy Canada hosts many events and initiatives to raise funds. The funds raised help provide research and services for people with neuromuscular disorders. Muscular Dystrophy Canada events also raise awareness about these disorders and get entire communities involved. [4] Some of these fundraising efforts are:
Muscular dystrophies (MD) are a genetically and clinically heterogeneous group of rare neuromuscular diseases that cause progressive weakness and breakdown of skeletal muscles over time. The disorders differ as to which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. Some types are also associated with problems in other organs.
Limb–girdle muscular dystrophy (LGMD) is a genetically heterogeneous group of rare muscular dystrophies that share a set of clinical characteristics. It is characterised by progressive muscle wasting which affects predominantly hip and shoulder muscles. LGMD usually has an autosomal pattern of inheritance. It currently has no known cure or treatment.
Muscular Dystrophy Association (MDA) is an American nonprofit organization dedicated to supporting people living with muscular dystrophy, ALS, and related neuromuscular diseases. Founded in 1950 by Paul Cohen, who lived with muscular dystrophy, MDA accelerates research, advances care, and works to empower families to live longer and more independent lives but is perhaps known for its working relationship with world-renowned comedian, actor and entertainer Jerry Lewis, its national chairman of 55 years and host of the annual live Labor Day Telethon, along with more support from Don Rickles, Frank Sinatra, Milton Berle, Sammy Davis Jr., Rip Taylor and Dean Martin. The organization's headquarters is in Chicago, Illinois.
Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy predominantly affecting boys. The onset of muscle weakness typically begins around age four, with rapid progression. Initially, muscle loss occurs in the thighs and pelvis, extending to the arms, which can lead to difficulties in standing up. By the age of 12, most individuals with Duchenne muscular dystrophy are unable to walk. Affected muscles may appear larger due to an increase in fat content, and scoliosis is common. Some individuals may experience intellectual disability, and females carrying a single copy of the mutated gene may show mild symptoms.
Becker muscular dystrophy (BMD) is an X-linked recessive inherited disorder characterized by slowly progressing muscle weakness of the legs and pelvis. It is a type of dystrophinopathy. The cause is mutations and deletions in any of the 79 exons encoding the large dystrophin protein, essential for maintaining the muscle fiber's cell membrane integrity. Becker muscular dystrophy is related to Duchenne muscular dystrophy in that both result from a mutation in the dystrophin gene, however the hallmark of Becker is milder in-frame deletions. and hence has a milder course, with patients maintaining ambulation till 50–60 years if detected early.
Oculopharyngeal muscular dystrophy (OPMD) is a rare form of muscular dystrophy with symptoms generally starting when an individual is 40 to 50 years old. It can be autosomal dominant neuromuscular disease or autosomal recessive. The most common inheritance of OPMD is autosomal dominant, which means only one copy of the mutated gene needs to be present in each cell. Children of an affected parent have a 50% chance of inheriting the mutant gene.
In medicine, myopathy is a disease of the muscle in which the muscle fibers do not function properly. Myopathy means muscle disease. This meaning implies that the primary defect is within the muscle, as opposed to the nerves or elsewhere.
Nemaline myopathy is a congenital, often hereditary neuromuscular disorder with many symptoms that can occur such as muscle weakness, hypoventilation, swallowing dysfunction, and impaired speech ability. The severity of these symptoms varies and can change throughout one's life to some extent. The prevalence is estimated at 1 in 50,000 live births. It is the most common non-dystrophic myopathy.
Facioscapulohumeral muscular dystrophy (FSHD) is a type of muscular dystrophy, a group of heritable diseases that cause degeneration of muscle and progressive weakness. Per the name, FSHD tends to sequentially weaken the muscles of the face, those that position the scapula, and those overlying the humerus bone of the upper arm. These areas can be spared, and muscles of other areas usually are affected, especially those of the chest, abdomen, spine, and shin. Almost any skeletal muscle can be affected in advanced disease. Abnormally positioned, termed 'winged', scapulas are common, as is the inability to lift the foot, known as foot drop. The two sides of the body are often affected unequally. Weakness typically manifests at ages 15–30 years. FSHD can also cause hearing loss and blood vessel abnormalities at the back of the eye.
George Karpati, was a Canadian neurologist and neuroscientist who was one of the leading experts on the diagnosis and treatment of neuromuscular disorders including muscular dystrophy research.
A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit. Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur.
Congenital muscular dystrophies are autosomal recessively-inherited muscle diseases. They are a group of heterogeneous disorders characterized by muscle weakness which is present at birth and the different changes on muscle biopsy that ranges from myopathic to overtly dystrophic due to the age at which the biopsy takes place.
The MDA Labor Day Telethon was an annual telethon held on Labor Day in the United States to raise money for the Muscular Dystrophy Association (MDA). The Muscular Dystrophy Association was founded in 1950 with hopes of gaining the American public's interest. The show was hosted by comedian, actor, singer and filmmaker Jerry Lewis from its 1966 inception until 2010. The history of MDA's telethon dates back to the 1950s, when the Jerry Lewis Thanksgiving Party for MDA raised funds for the organization's New York City area operations. The telethon was held annually on Labor Day weekend beginning in 1966, and raised $2.45 billion for MDA from its inception through 2009.
Sarcospan is a protein that in humans is encoded by the SSPN gene.
The ALS Society of Canada is a registered, not-for-profit Canadian organization. ALS Canada, founded in 1977, is a national voluntary health organization dedicated to the fight against amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, and to providing support for those living with ALS.
The goal of physical and occupational therapy in Duchenne muscular dystrophy is to obtain a clear understanding of the individual, of their social circumstances and of their environment in order to develop a treatment plan that will improve their quality of life. Individuals with DMD often experience difficulties in areas of self-care, productivity and leisure. This is related to the effects of the disorder, such as decreased mobility; decreased strength and postural stability; progressive deterioration of upper-limb function; and contractures. Occupational and physical therapists address an individual's limitations using meaningful occupations and by grading the activity, by using different assessments and resources such as splinting, bracing, manual muscle testing (MMT), ROM, postural intervention and equipment prescription.
Muskelsvindfonden is a Danish non-profit organization that strives to find a cure for neuromuscular disorders. Founded in 1971 volunteers and staff nationwide have helped to provide support and resources to those affected.
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a very rare neurodegenerative genetic disorder that primarily affects people from the Charlevoix and Saguenay–Lac-Saint-Jean regions of Quebec or descendants of native settlers in this region. This disorder has also been demonstrated in people from various other countries including India, Turkey, Japan, the Netherlands, Italy, Belgium, Finland, France, and Spain. The prevalence has been estimated at 1 in 1,900 in Quebec, but it is very rare elsewhere.
Pseudohypertrophy, or false enlargement, is an increase in the size of an organ due to infiltration of a tissue not normally found in that organ. It is commonly applied to enlargement of a muscle due to infiltration of fat or connective tissue, famously in Duchenne muscular dystrophy. This is in contrast with typical muscle hypertrophy, in which the muscle tissue itself increases in size. Because pseudohypertrophy is not a result of increased muscle tissue, the muscles look bigger but are actually atrophied and thus weaker. Pseudohypertrophy is typically the result of a disease, which can be a disease of muscle or a disease of the nerve supplying the muscle.
