The IHS criteria for migraine without aura have poor sensitivity but high specificity using a clinical diagnosis as the gold standard. The IHS criteria should be modified to better reflect current pediatric clinical practice.

Migraineurs with disabling attacks may be prone to ANS hypofunction. These findings may suggest that ANS dysfunction either may be a risk factor for migraine headaches or be a consequence of frequent disabling attacks. Moreover, ANS dysfunction and migraine may share a common neural substrate.

Transcranial magnetic stimulation thresholds are lower in subjects with migraine compared with controls. The reported phosphene threshold is lowered with repeated measurement. Neither high nor low phosphene thresholds predict a subsequent headache, nor do migraines predict a subsequent high or low threshold.
