MELAS Syndrome Center

MELAS syndrome, a rare form of dementia, stands for Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-like episodes. Mutations in the genetic material (DNA) in the mitochondria cause MELAS syndrome. Symptoms of MELAS include:

  • brain dysfunction (encephalopathy) with seizures and headaches,
  • muscle disease with lactic acid build-up in the blood,
  • temporary local paralysis,
  • and abnormal thinking (dementia).
There is no known treatment for MELAS. Read more: MELAS Syndrome Article
