The identification of
comorbid disorders in migraineurs
is important since it may impose
therapeutic challenges and limit
treatment options. Moreover, the
study of comorbidity might lead to
improve our knowledge about
causes and consequences of
migraine. Comorbid neuropathologies
in migraine may involve
mood disorders (depression,
mania, anxiety, panic attacks),
epilepsy, essential tremor, stroke,
and white matter abnormalities.
Particularly, a complex bidirectional
relation exists between migraine
and stroke, including migraine as a
risk factor for cerebral ischemia,
migraine caused by cerebral
ischemia, migraine as a cause of
stroke, migraine mimicking cerebral
ischemia, migraine and cerebral
ischemia sharing a common
cause, and migraine associated
with subclinical vascular brain
lesions.
