An international research consortium has shown that an accumulation of many independent genetic risk variants is the reason why migraine tends to run in families. The genetic burden was shown to be greater in patients that experience aura symptoms during attacks or have an early age of onset of migraine.
The results of the largest genetic family study on migraine thus far were published online in the journal
Neuron today, May 3. The study was based on medical history and genetic data of 1,589 Finnish migraine families with more than 8,300 individuals.
