Tests & Diagnosis
On this page
Hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC) is diagnosed by a magnetic resonance imaging (MRI) scan of the brain. When the following three features are identified in the brain of an affected individuals, the diagnosis of H-ABC can be made:
- Decreased myelin (hypomyelination) in the brain. Myelin usually forms a protective covering around brain cells. In H-ABC, this covering is thinner than usual which makes it difficult for nerve cells to work properly.
- Breakdown (atrophy) of the basal ganglia, a part of the brain that directs and controls movement.
- Atrophy of the cerebellum, another part of the brain that controls movement.
