Leigh Syndrome

Leigh syndrome is a rare, inherited neurodegenerative disorder and is considered one of the Mitochondrial Disorders. It is caused by a defect in the function of mitochondria within the cells of the body. Mitochondria are responsible for creating more than 90% of the energy needed by the body to sustain life and support growth. When they fail, less and less energy is generated within the cells. The infant first is unable to absorb food, and thus cannot grow and gain weight as expected (failure to thrive). Progressive damage to the central nervous system may lead to loss of mental and motor ability. There is currently no cure or treatment for Leigh syndrome.
