Disability Tax Credits and Benefits for Myasthenia Gravis


Muscle weakness is one of the most common problems faced by most people in today’s world. Though it is a general symptom for many diseases and illness, the weakness of bones and muscles can sometimes occur as a result of a neurological disorder. Those people who tend to experience weakness of their muscles, which they should be able to control without weakness, might suffer from a condition called myasthenia gravis. Myasthenia gravis is a neurological disorder that affects the voluntary muscles, by restricting the communication between nerves and muscles. This disease is categorized as an autoimmune disease. Autoimmune refers to a condition that occurs when a person’s own immune system develops antibodies that affect his or her own cells, tissues and nerves. A person becomes affected by myasthenia gravis when the person’s immune system affects the signals that are being passed between nerves and the muscles. This disease can easily be treated with the help of medicine that improves the nerve-muscle communication. The condition can be made better by resting as much as possible. This disease does not usually create immediate life threatening situations. Those people who are affected by myasthenia gravis can avail the disability tax credit and other benefits from the Canadian government.


As mentioned earlier, the major cause of myasthenia gravis is the lack of communication between the nerves and muscles. Let’s explore how this communication defect occurs. The neuromuscular junction is a critical region where the nerves and muscles become connected to one another. While sending signals to the muscles, the nerves release a neurotransmitter at the neuromuscular junction. These transmitters are then connected to the corresponding receptors, which results in muscle contraction. A person who is affected by myasthenia gravis does not receive these signals, as the antibodies tend to block the receptors at the neuromuscular junction. Hence, the contraction of muscles does not take place. Sometimes, tumours in the thymus might cause in myasthenia gravis.


There are several symptoms that could be present in an individual with myasthenia gravis. The following is a list of symptoms that could help determine the presence of the condition in a person:

  • Myasthenia gravis mostly affects the movement of the voluntary muscles.
  • Among the voluntary muscles, the muscles that are responsible for eyelid movements will be the first to get affected.
  • People with myasthenia gravis could face difficulty in swallowing food.
  • Some people might find it hard to speak clearly.
  • The extent to which the muscles become weakened is determined by the severity of the disease.
  • In a localized condition, only certain muscles are affected, whereas in cases of severe infection, the muscles, which are involved in respiration, are affected, which causes difficulty breathing.
  • If the eye muscles are affected to a greater extent, patients may experience double vision or blurred vision.
