Seasonal Variation, Cranial Autonomic Symptoms, and Functional Disability in Migraine: A Questionnaire‐Based Study in Tertiary Care

Abstract

Patients who reported seasonal variation in migraine also reported more CASs and had more severe functional disability. The profound functional disability in the migraineurs reporting seasonal variation or CAS also provides direction for proactive clinical management in these patients.

Allergic Rhinitis and Chronic Daily Headaches: Is There a Link?

“…Another common feature of allergic rhinitis and migraine is their seasonal exacerbation in the spring, fall, and summer months as a result of allergic triggers [ 35 •, 39 , 48 , 49 ]. A study from South Korea conducted between 2005 and 2013 showed that 13.5 % of migraine patients reported seasonal exacerbations [ 48 ].…”

“…Another common feature of allergic rhinitis and migraine is their seasonal exacerbation in the spring, fall, and summer months as a result of allergic triggers [ 35 •, 39 , 48 , 49 ]. A study from South Korea conducted between 2005 and 2013 showed that 13.5 % of migraine patients reported seasonal exacerbations [ 48 ]. Moreover, the costs of migraine treatment are higher during allergy season [ 49 ], because many people with migraine experience an increase in headache intensity and frequency due to coexisting allergic rhinitis [ 50 ].…”

Photophobia and Seasonal Variation of Migraine in a Subarctic Population

“…Furthermore, attenuation of the pupillary light reflex, as documented both in the wake of migraine attacks and in the interictal phase of cluster headache has been suggested as a hypothalamic compensatory mechanism due to increased locus coeruleus‐activity. In view of that, SM may represent a state with increased hypothalamic dysfunction as reflected in the Korean study where they found increased cranial autonomic symptoms (CAS) in patients who reported seasonal variation . Unfortunately, the frequency of CAS in the present cross‐sectional was not evaluated.…”

“…The present survey is not optimally designed to give the answers, but patients in our clinical practice have reported less severe headache when using preventive treatment only in the polar day season . Subsequently, 769 Korean migraineurs without aura reported SM in 104 (13.5%) of the participants . These patients had more cranial autonomic symptoms, photophobia, phonophobia, neck pain, and intolerance to physical activity, weekend migraine, and functional disability than others …”
