Converging neuropsychological evidence suggests that in migraine executive functions (EF) may be affected during interictal periods. ⋯ Our data suggest that, even in the absence of clinically evident EF deficits, MwoA is associated with reduced FPN functional connectivity. This study provides further insights into the complex scenario of migraine mechanisms.

Allodynia is frequently associated with migraine and other primary headaches. Our aim was to investigate the presence of allodynia and related features in idiopathic intracranial hypertension (IIH), which is a disabling secondary headache disorder. ⋯ Half of the IIH patients reported allodynia, and these allodynic patients had mostly migraine-like headache profiles. Our study suggested that IIH may trigger some common mechanisms with migraine in pain pathways causing allodynia.
