Lissencephaly
Also known as: Lissenzephalie · Smooth brain syndrome · Agyria · Agyrie · Cerebral lissencephaly · …
Overview
What it is
Lissencephaly is an inherited brain malformation where the cerebral cortex, which is the outer layer of the brain, fails to develop its normal folds and remains abnormally smooth. This genetic defect disrupts how nerve cells migrate during development, severely impairing the central nervous system's ability to process information.
How it presents
Symptoms typically appear in puppies between two and four months of age. Owners usually notice severe learning difficulties, coordination problems, blindness, and frequent, difficult-to-control seizures.
Treatment
This condition is incurable, and treatment is limited to lifelong supportive care to manage symptoms like seizures. Managing this care typically costs between 1,000 and 3,500 EUR.
How it's tested
