polymyositis and dermatomyositis can be treated effectively with drugs that suppress the immune system. Myasthenia Gravis In myasthenia gravis, the body’s immune system inappropriately injures a specialized muscle structure called the acetylcholine receptor. Damage to these receptors leads to the typical symptom of this disease, namely easy fatigue and increased weakness on exertion. Often, the eyes are affected with drooping of the upper eyelids and double vision. Generalised weakness and difficulty with swallowing or speaking is common. This disease will also respond effectively to treatments that suppress the immune system.

Infections tetanus (paralyzing bacterial infection) 4. Miscellaneous Cerebral palsy A broad term used to describe impairment or loss of motor function as a result of brain damage. It is believed that this damage occurs while still in the mother’s womb, as those with cerebral palsy are born with it. However, there are cases where the development of cerebral palsy can occur after birth. This condition affects muscle control, body movement, muscle coordination, reflexes, muscle tone, and balance.

Amyotrophic lateral sclerosis ALS is characterized by muscle weakness and atrophy—muscle wasting. It is due to the degeneration of upper and lower motor neurons of the body that are responsible for voluntary movement. Affected individuals ultimately lose their ability to initiate and control all voluntary movement, though bowel and bladder function, as well as eye movements, are typically spared. While behavioral and cognitive functioning usually remains intact, a small percentage may show signs of frontotemporal dementia. The disease can strike at any age but most commonly develops between the ages of 55 and 75.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
