EEG can help exclude seizure disorders and recurrent episodes of confusion. Otherwise, EEG is unnecessary in the management of migraine variants.

Genetic testing can be performed to detect point mutations in CACNA1A and ATP1A2 for familial hemiplegic migraine. It may also be performed for other migraine-associated conditions, such as cerebral autosomal dominant arteriopathy and subcortical infarcts and leukoencephalopathy (CADASIL), which is an autosomal dominant disorder that appears in early adulthood with migraine, multiple subcortical strokes, and dementia.

SPECT scanning may show hypoperfusion during the aura phase. CT scanning or MRI is indicated for a first attack of focal neurologic deficits or altered mental status, or when focal findings persist between attacks.
