[Migraine and psychosomatic comorbidity].

As a common neurological disorder (10-15% of the population), migraine is associated with numerous comorbidities, particularly other pain syndromes, mental illnesses and functional disorders. These 'psychosomatic' comorbidities increase with migraine severity. Severely affected, comorbid patients also often have a poorer response to specific migraine therapy. Interestingly, migraine and the comorbidities mentioned have a number of common aetiological or facilitating factors, e.g. genetic factors, and show a higher incidence in women and in people with previous traumatic experiences, as well as (in the case of pain syndromes) signs of central sensitization. Another common feature is the association with current or chronic stress. We propose an extended diathesis-stress model that takes into account interrelated but individually different vulnerabilities and, depending on the stress experience, can depict both the occurrence of individual disorders (e.g. an isolated migraine) and the joint occurrence of migraine with other pain syndromes and other psychosomatic comorbidities. In summary, psychosomatic comorbidities should always be kept in mind in migraine therapy and, if necessary, treated early and multimodally.
