Structural problems usually show on cranial magnetic resonance imaging. The age of onset often helps to reach a diagnosis in chronic cerebellar disorders. Many genetic conditions present at a younger age, whereas other conditions such as multiple system atrophy present at an older age. Cranial imaging can help in chronic cerebellar disorders: some conditions cause cerebellar atrophy (e.g. ataxia telangiectasia) whereas others usually do not (e.g. Friedreich’s ataxia).
