It is only within the past 40 years that the term "migraine art" was introduced; yet artists may have been creating works inspired by migraine aura since the Stone Age. Early depictions of migraine continue to influence newer artists with this illness. This is a natural progression that is common in all types of art, according to Klaus Podoll, MD, senior physician in the department of psychiatry and psychotherapy, University Hospital Aachen, RWTH Aachen University, Germany. But Dr Podoll has found that artists with migraine are often particularly attracted to the works of other artists who share their migraine experiences. These shared experiences "act like a filter," contributing to the an artist's perspective and leading to "elective affinities between migraine-inspired artists," he said.
