Given what you know, would you rather be diagnosed with myasthenia gravis or polio? Back up your choice with evidence about the symptoms and potential treatments for each disorder.
What will be an ideal response?
Answers will vary depending on choice. Symptoms of each disorder:Myasthenia gravis results when a person's immune system, for reasons that are not well understood, produces antibodies that bind to the nicotinic ACh receptor. Over time, the ACh receptors degenerate and become less efficient, leading to extreme muscle weakness and fatigue. The degeneration usually affects the muscles of the head first, resulting in droopy eyelids and slurred speech. As the degeneration proceeds, the patient might experience difficulty swallowing and breathing. Myasthenia gravis is typically treated with medications that suppress the immune system.Polio, or poliomyelitis, occurs only in human beings and is caused by a contagious virus that specifically targets and destroys spinal alpha motor neurons. Symptoms can include muscle weakness and paralysis, usually of the legs. If the infection affects higher levels of the central nervous system, breathing can be affected. This situation leads to the patient's reliance on assisted respiration, such as an "iron lung." A vaccine against polio was developed and almost all cases in the United States have been eliminated.
