What is MELAS Syndrome?

MELAS syndrome is a rare genetic disorder that affects many parts of the body, especially the brain and muscles. The name MELAS stands for Mitochondrial Encephalomyopathy, Lactic Acidosis, and Stroke-like episodes. People with this condition may experience a range of symptoms, making everyday life challenging. Understanding MELAS is crucial for those affected and their families, as it helps in managing the condition effectively.

MELAS syndrome is a type of mitochondrial disorder, which means it is caused by problems in the mitochondria. Mitochondria are the energy-producing parts of our cells. When they don’t work properly, it can lead to a shortage of energy, affecting various organs and systems in the body. This condition typically appears in childhood or early adulthood and can lead to serious complications.

Pathophysiology

1. Structure:
   • MELAS primarily affects the brain and muscles. In the brain, areas responsible for movement and coordination may be damaged, leading to symptoms like weakness or difficulty with balance.
2. Blood:
   • The syndrome can cause problems with blood flow and oxygen delivery, leading to lactic acidosis, a condition where the body produces too much lactic acid.
3. Nerve Supply:
   • Nerve cells may be affected, leading to symptoms such as seizures, headaches, and cognitive decline.

Types of MELAS Syndrome

There are various manifestations of MELAS syndrome, often categorized by the severity and types of symptoms present. Understanding these types can help in diagnosing and managing the condition.
