Mitochondrial diseases result from failures of the mitochondria, specialized compartments present in every cell of the body (except red blood cells).
Mitochondria are responsible for creating more than 90% of the energy needed by the body to sustain life and support organ function. When they fail, less and less energy is generated within the cell. Cell injury and even cell death follow. If this process is repeated throughout the body, whole organ systems begin to fail.
The parts of the body, such as the heart, brain, muscles and lungs, requiring the greatest amounts of energy are the most affected.  Mitochondrial disease is difficult to diagnose, because it affects each individual differently. Symptoms can include seizures, strokes, severe developmental delays, inability to walk, talk, see, and digest food combined with a host of other complications. If three or more organ systems are involved, mitochondrial disease should be suspected.
Although mitochondrial disease primarily affects children, adult onset is becoming more common.
