Myasthenia gravis

Myasthenia gravis What is myasthenia gravis? Myasthenia gravis is a medical condition characterized by autoantibodies against acetylcholine receptors at the neuromuscular junction, resulting in muscle weakness. Patients often have involvement of their ocular (eye) and bulbar muscles. The bulbar muscles are located in the head and are important for chewing and swallowing. Symptoms often include double vision, eyelid drooping, slurred speech, and dysphagia (trouble swallowing) due to muscle fatigue – this is particularly worse at the end of the day. Patients may have acute flares of disease referred to as “myasthenic crisis.” During these episodes, patients have muscle weakness involving the diaphragm, which is a critical muscle for breathing.…

Myasthenia Gravis is considered an “autoimmune neuromuscular disease” that is categorized by the different amounts of weakness of the skeletal muscles in the body. The cause of Myasthenia Gravis is a flaw in the transmission of the nerve impulses to the muscles in the body. When normal communication between nerves and muscles are distributed at the neuromuscular junction, Myasthenia Gravis occurs. In normal humans, when an impulse travels down a nerve, the nerve then releases a neurotransmitter…

Myasthenia gravis is a neurological disorder that affects the immune system and causes chronic muscle weakness in the skeletal muscles of the human body. The name myasthenia gravis means "grave muscle weakness". A strong indication of myasthenia gravis is muscle weakness that heighten during periods of physical activity and decrease after resting periods. Muscles like those that control eye and eyelid movement, facial expression, eating, speaking, breathing and neck and limb movements can all…

Introduction Myasthenia gravis is a neuromuscular autoimmune disorder that affects the skeletal muscles in the body. This disorder is mainly characterized by periods of weakness in the body. The Latin meaning for myasthenia gravis is grave muscle weakness (Lewis 2007). In the United States the prevalence rate is 14 per 100,000 (Lewis 2007) myasthenia gravis can affect any age, but normally it affects people over the age of 50 (Lewis 2007) The mortality rate from myasthenia gravis…

Myasthenia gravis is a neuromuscular disorder or autoimmune disorder. An autoimmune disorder occurs when the immune system mistakenly attacks its own healthy tissue. Neuromuscular disorders involve the muscles and the nerves that control them. With myasthenia gravis, the body produces antibodies that block the muscle cells from receiving messages (neurotransmitters) from the nerve, which causes weakness of the voluntary muscles. Therefore, fewer receptors are available for stimulation, resulting…

Myasthenia gravis is a chronic autoimmune disease that targets the neuromuscular junction resulting in impaired impulse transmission and skeletal muscle weakness. The muscular weakness may exacerbate during periods of activity while improving after periods of rest, occurring with various severities. Muscles that control the eyes, eyelids, facial expression, swallowing, and talking can also be affected. Symptoms are presented as drooping of the eyelids, called ptosis, blurred or double vision,…

Do you even wonder how it feels to go a day in the world feeling as if you were a noodles, with no strength to do anything? However, some people may say to just exercise and gain strength. Some of us may not have that option. People call us lazy, liars, or over reacting. Though, our true name is Myasthenia Gravis warrior or fallen snow flake. Myasthenia Gravis, MG for short, is a “chronic autoimmune neuromuscular disorder that is characterized by fluctuating weakness of the voluntary muscle…

Myasthenia Gravis Background Myasthenia gravis is a Type II autoimmune disorder in which antibodies form against various types of receptors, kinases, or proteins (1). There are four subtypes of myasthenia gravis, with the most prevalent subtype being due to autoantibodies against the muscle-type acetylcholine receptor, AChR, at the neuromuscular junction (2; 3). The second subtype involves antibodies against the muscle-specific kinase, MuSK, and the third type is due to autoantibodies against…

worldwide have Myasthenia Gravis (Myasthenia Gravis, 2012). Myasthenia Gravis is a disorder that causes skeletal muscle weakness. People experience the worst weakness during periods of activity and the weakness improves under periods of rest. The most common weakness is located in the muscles around the eyes. This causes blurred or double vision in the eyes. It also effects the muscles used in facial expression and chewing. These conditions can cause difficultly chewing, swallowing, and…

Myasthenia Gravis is a chronic autoimmune disorder that causes weakness and rapid fatigue in the skeletal muscles, these muscles are responsible for breathing and moving. Some of the muscles affected include, control of eye movements, facial expressions, chewing, talking and swallowing. Other symptoms would include, shortness of breath, weakness in arms, hands, fingers, legs and neck. Myasthenia Gravis is a rare disease that may be difficult to diagnose. Myasthenia Gravis occurs when there is an…
