MELAS

MELAS Syndrome
This term refers to a group of disorders having somewhat similar clinical features secondary to mutations in the DNA of mitochondria which leads to deficits in cellular energy pathways.

What is MELAS?
Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) is a condition that affects many of the body's systems, particularly the brain and nervous system (encephalo-) and muscles (myopathy).

MELAS is a rare form of dementia. MELAS is an abbreviation that stands for Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-like episodes.
What causes MELAS?

How is MELAS diagnosed?
The diagnosis of MELAS is usually suspected on clinical grounds. However, confirmation of the diagnosis usually requires a muscle or brain biopsy.

MELAS is a form of dementia. It is caused by mutations in the genetic material (DNA) in the mitochondria. While most of our DNA is in the chromosomes in the cell nucleus, another important cell structure that carries DNA is the mitochondrion.

Patients with MELAS are born with mutations in the genetic material (DNA) inside the mitochondria of their cells. The mitochondria produce the energy that cells need to perform everyday functions.
