Common causes of neuromuscular disorders include heredity and genetic mutations that may be present from birth or early childhood. Other causes can include autoimmune disorders and exposure to environmental toxins. Ultimately, we do not have a complete understanding of the causes, single or multiple, of neuromuscular disorders.
Treatments for Neuromuscular Disorders
There are no curative treatments for neuromuscular disorders and most treatment plans revolve around the management of symptoms.
Symptoms and Diagnosis
Most neuromuscular disorders begin by affecting large skeletal muscles, such as those in the arms and legs, but can progress to affect the smaller muscles of the eyes, throat, and chest, which can lead to other problems.
Muscular Dystrophies
Muscular dystrophies are a group of genetic diseases characterized by a gradual loss of motor function, muscle weakness and wasting away, gait problems, progressive respiratory failure, and cardiomyopathy.
Myopathies
Myopathies, meaning diseases of muscles, are classified into the following categories: 4
Motor Neuron Diseases
Motor neuron diseases damage motor neurons, which are specific nerve cells that control contraction of muscle fibers. With motor neuron diseases, the muscles become weak and lose function over time from a lack of electrical signaling from the nerves to the muscles.
Ion Channel Diseases
Ion channel diseases are a group of disorders that affect the ability of muscles to contract due to altered levels of potassium ions in the blood. This often results in periodic paralysis or temporary loss of the ability to contract muscles.
Mitochondrial Diseases
Mitochondria are in nearly every cell of the body, and are responsible for processing oxygen and converting substances from the foods we eat into energy. Mitochondria produce 90% of the energy our bodies need to function. 1
Neuromuscular Junction Diseases
Neuromuscular junction diseases affect the neuromuscular junction, the gap between a nerve cell and a muscle fiber where the neurotransmitter acetylcholine is released from the nerve to elicit contraction of the muscle fiber.
