Muscular Dystrophy- Types, Causes, Signs & Symptoms » Symptoms of Muscular DystrophyThere are different types of conditions that cause muscular disorders. Muscular dystrophy is one of them and it slowly leads to the malfunction and complete failure of the muscles. Specialists still do not know the exact cause of this disease, although it is said that hereditary factors play a big role in its cause.

Types of muscular dystrophy
Muscular dystrophy has been classified into different types depending on which part of the body it affects .We have myotonic muscular dystrophy also known as Thomsens disease which damages the muscles in the hands and feet, Limb-girdle damages the shoulders and hips, Steinert’s disease only affects the upper arms, face and shoulders and Landouzy-Dejerine muscular dystrophy which damages the face, shoulder and lower leg muscles.

Very few people are known to suffer from any of these muscular disorders and out of the known cases; Duchenne’s muscular dystrophy has been the most frequently diagnosed form of all the muscular disorders. In every 10,000 young men, two suffer from Duchenne’s.

No one knows the exact cause of this disease although it is has been noted that individuals who suffer from these muscular disorders have one thing in common, which is a defective gene. Women are said to be carriers since they carry the defective gene in the x chromosome which always remains normal. Men suffering from Duchenne’s muscular dystrophy lack a muscle protein called dystrophin.

This protein is responsible for the structuring of the muscle cells. While persons suffering from Becker’s muscular dystrophy are able to produce dystrophin, it is abnormally large, impairing its functionality.

Symptoms of Duchenne’s muscular dystrophy
The symptoms begin to present themselves in young boys between 3 to 7 years. One begins to develop weakness around the pelvic muscles which gradually grows and also affects the muscles round the shoulders. Muscle tissues enlarge and weaken rapidly as the disease progresses. The heart muscles are also affected causing irregular heartbeats.

The affected person gradually experiences difficulties in walking, climbing stairs and standing in an upright position .They get to a point where stretching out their arms and legs becomes impossible. They finally become bound to the wheelchair.
