The problem of comorbidity in migraine without aura

Objective: to analyze the frequency of occurrence and structure of comorbid disorders in patients with rare episodic, frequent episodic and chronic migraine without aura. Material and methods. Outpatient records of 159 patients with migraine without aura were analyzed: 52 with rare episodic migraine (REM), 54 with frequent episodic migraine (FEM), 53 with chronic migraine (CM). All patients underwent a clinical and psychological examination with an assessment of the state of the temporomandibular joint, frontal, occipital muscles, neck muscles (pericranial muscles) and chewing muscles with an emphasis on the pterygoid muscles. All patients were consulted by a clinical psychologist. Results. Additional headache symptoms have been identified in various forms of migraine. In the structure of comorbid conditions, the following were noted more often than others: disorder of pericranial muscles (REM 59.6%, FEM 72.2%, CM 90.5%), dysfunction of the temporomandibular joint (REM 21.1%, FEM 22.2%, CM 54.7%), anxiety-depressive disorders (REM 26.9%, FEM 35.2%, CM 58.5%), insomnia (FEM 22.2%, CM 39.6%). With CM, there is a high percentage of medication-overuse headache (73.6%). Conclusion. Comorbid disorders occur with varying frequency depending on the form of migraine. Among comorbid disorders, muscle dysfunction, dysfunction of the temporomandibular joint, anxiety and depressive disorders, and sleep disorders predominate.
