Neuromuscular disease

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, called diplopia, impaired speech, called dysarthria, shortness of breath, difficulty swallowing, waddling gait, and fatigued arms and legs. Although myasthenia gravis can affect people of all ages, it is most common among women under 40 and men above the…

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 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…

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…

between nerves and muscles is disturbed. The nerve endings will usually release a neurotransmitter substance called acetylcholine to the body’s muscles. Acetylcholine generates a muscle contraction. Those with myasthenia gravis have an absence of acetylcholine. In the case of myasthenia gravis, the body’s antibodies stop, change, or kill the acetylcholine receptors, inhibiting the muscle from contracting.The immune system creates these antibodies to fight off infection. Myasthenia gravis is…

Introduction Monoclonal gammopathy of undetermined significance (MGUS) is condition in which there is too much of a protein called monoclonal protein, or M protein, in the blood. MGUS can cause there to be too many cells in your blood and not enough space for healthy cells. This condition increases your risk of cancer. What are the causes? The cause of this condition is not known. What increases the risk? You are more likely to develop this condition if: You are African American. You are 50…

Inclusion Body Myositis is a neuro-muscular disease affecting people over fifty, mostly males, is characterized by progressive muscle weakness and atrophy in key muscles in the arms (forearm flexors) and the legs (quadriceps), resulting in severe disability. IBM is generally a slowly progressive disease and life expectancy isn’t significantly affected. Ted was diagnosed with IBM in 2012 when he was 68 years old, but his muscle biopsy showed that he has had it 10 to 15 years prior to the…

Morgellons disease is an interesting disease that is very rare and often hard to diagnose correctly. This particular disease is very hard to clarify. The symptoms can be different from varying patients. However, general symptoms include crawling senses under the skin, itching, black dots in the skin, thread-like fibers coming from the skin or underneath the skin, joint pain, trouble sleeping, panic attacks, memory loss and skin rashes. Not all patients have these symptoms but the two that almost…

Hereditary canine spinal muscular atrophy (HCSMA) is proven to be an autosomal-dominate disease that affects most noticeably the Brittany spaniel (Pinter MJ, Waldeck RF, Wallace N, & Cork LC, Motor Unit Behavior in Canine Motor Neuron Disease, 1995). HCSMA originated as a spontaneous mutation in the Survivor Motor Neutron gene found in the purebred Brittany spaniel population (Ericsson. A & Rubin. C, 2012). Due to the co-dominate nature of the disease there are slight variation in the phenotype…
