A group of brain conditions in which the brain lacks its usual folds, affecting how it works.

Understanding Lissencephaly

Lissencephaly is a group of diseases that affect the way the brain looks, with a lack of the brain's usual folds (convolutions).

It happens because nerve cells (neurons) don't move to the right places during brain development before birth. This affects how the brain works. It is noticed in newborns and infants.
