For World Mental Health Day, October 10^th, Cristina Tassorelli, Professor of Neurology, University of Pavia, Italy, discusses how awareness of migraine is important as it may be an ‘invisible’ illness. This is due to a person predominantly being seen in public only in the interictal period, so not thought of as having a chronic, life-affecting condition. While migraine is not classed as a mental health disorder, psychiatric conditions, including anxiety and depression, may be comorbid and a patient’s quality of life can be poor.
