ALO is often a benign and unilateral condition, and extensive evaluation may not be necessary. The diagnosis may be a clinical diagnosis based on a thorough history and physical exam, and being able to exclude other diagnoses and pathology. Computed tomography (CT) or magnetic resonance imaging (MRI) may be ordered to help determine whether there is a lesion or other pathological cause present in the brain or brainstem. Electromyography may be used to aid the diagnosis.
