Mitochondrial diseases and stroke

We review the mitochondrial diseases in which cerebrovascular changes are seen, such as the MERRF syndrome (myoclonic epilepsy and ragged red fibers) or the Kearns-Sayre syndrome (progressive external ophthalmoplegia, retinitis pigmentaria, cerebellar disorders and disorders of cardiac conduction), focusing on the syndrome involving mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS).

We consider the different clinical aspects, diagnostic methods, pathophysiological mechanisms of the cerebrovascular involvement as well as therapeutic approaches.
