Mitochondrial disease is a term used to describe a range of illnesses caused by mitochondrial malfunction. Mitochondria are energygenerating organelles present in all cells of the human body except red blood cells. They transform food molecules' energy into ATP, which drives most cell processes. Mitochondrial diseases (MD) are a wide set of mitochondrial dysfunction-related maternally inherited, autosomal dominant, or recessive genetic abnormalities. MD can strike at any age, and many of them appear with a multisystem presentation and a wide range of symptoms. Because mitochondria play such an essential part in neural homeostasis, neurological symptoms such as movement disorders are common.
