Although there is no cure for mitochondrial myopathy, many of the problems associated with it can be treated effectively.
For instance, you can treat diabetes with tablets or insulin, epilepsy with anti-epilepsy medications, deafness with hearing aids (or in some cases, cochlear implants), heart rhythm problems with pacemakers.
You can improve muscle fatigue with regular gentle exercise. The condition can improve in a few patients with specific vitamins such as ubiquinone (coenzyme Q10) and riboflavin, but not in most.
