Myopathy. The main symptoms of mitochondrial myopathy are muscle fatigue, weakness, and exercise intolerance. The severity of any of these symptoms varies greatly from one person to the next, even in the same family. In some individuals, weakness is most prominent in muscles that control movements of the eyes and eyelids.
What is mitochondrial disease?
In most cases, mitochondrial disease is a multisystem disorder affecting more than one type of cell, tissue, or organ. Because muscle and nerve cells have especially high energy needs, muscular and neurological problems are common features of mitochondrial disease.

What is mitochondrial myopathy?
Mitochondrial diseases are present with a wide range of clinical phenotypes . The organ systems most reliant on aerobic metabolism are preferentially affected. Myopathy may be the sole or main sign, or merely an incidental finding associated with a multisystemic illness. Involvement of the nervous system in general (referred to as mitochondrial encephalomyopathy) is common. When skeletal muscle is affected, either alone or with central nervous system disease, the term mitochondrial myopathy is used. Although mitochondria are known to play a role in diverse cellular functions including redox balance, apoptosis, fatty acid oxidation, and calcium homeostasis, this review will focus on the treatment of mitochondrial diseases due to pathologic dysfunction of the mitochondrial respiratory chain.

Overview
Myopathy refers to diseases that affect skeletal muscles (muscles that connect to your bones). These diseases attack muscle fibers, making your muscles weak.
Diagnosis and Tests
You should first contact your primary care doctor to alert them to the symptoms you’re concerned about. Depending on the nature of your symptoms, you might be referred to a specialist such as a neurologist or a rheumatologist.
Management and Treatment
After determining your specific type of myopathy, your healthcare provider will develop a treatment plan specific to your symptoms.
Living With
Although myopathy is a long-term (chronic) disease whether inherited or acquired, you can take steps to improve your health to help control your illness. These might include:
What are mitochondrial myopathies?
Mitochondrial myopathies are a group of neuromuscular diseases caused by damage to the mitochondria—small, energy-producing structures that serve as the cells' "power plants." Nerve cells in the brain and muscles require a great deal of energy, and thus appear to be particularly damaged when mitochondrial dysfunction occurs. Some of the more common mitochondrial myopathies include Kearns-Sayre syndrome, myoclonus epilepsy with ragged-red fibers, and mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes. The symptoms of mitochondrial myopathies include muscle weakness or exercise intolerance, heart failure or rhythm disturbances, dementia, movement disorders, stroke-like episodes, deafness, blindness, droopy eyelids, limited mobility of the eyes, vomiting, and seizures. The prognosis for these disorders ranges in severity from progressive weakness to death. Most mi...

Therefore, mitochondrial myopathies most commonly affect organs that consume a lot of oxygen such as muscles, the brain, and the heart. Symptoms may vary, but typically include muscle pain or weakness, double vision or blurry vision, droopy eyelids, difficulty breathing, and, in some forms, blindness, and seizures.
Why do mitochondria have their own DNA?
Mitochondrial myopathies caused by mutations in mitochondrial DNA can only be transmitted from the mother to her child because this type of DNA only comes from mothers. Mutations in mitochondrial DNA are responsible for disorders such as MELAS and Myoclonic Epilepsy with Ragged Red Fibers. Mutations in mitochondrial DNA can also cause Chronic Progressive External Ophthalmoplegia and Kearns-Sayre Syndrome.
