IMPACT OF WEATHER CONDITIONS ON MIGRAINE HEADACHE IN NORTH-EASTERN NIGERIA

摘要

Migraine.is.a.markedly.disabling.condition.and.exerts.a.significant.burden.on. the.sufferer.in.terms.of.pain,.suffering.and.imp aired.quality.of.life...This.study.aimed.to.assess.the.impact.of.weather.changes.in.migraine.attack...One.hundred.consecutive.adult.migraineurs.that.attended. the.Neurology. Clinic. of. the. Department. of. Medicine,. University. of. Maiduguri. Teaching. Hospital. from. May,. 2008. to. December,. 2009. and.met.the.inclusion.criteria.were.evaluated.using.structured.questionnaire...Eighty.four.percent.(84%).and.16%.of.the.studied.migraineurs.usually.found.dry.period.(November.‐.May).and.wet.period.(June.‐.October).unfavourable.respectively...Fourty.six.gets.their.migraine.triggered.during.the.warmest.months.(February.‐.May),.whereas.the.remaining.38.mostly.experienced.migraine.attack.during.harmattan.(November.‐.January).dry.period...Wet.weather.period.(high.humidity.plus.high.or.low.temperature).was.found.to.triggered.migraine.attack.in.16%.of.the.studied.migraine.patients..There.was. statistical. significant. difference. in. migraine. head. pain. due. to. wet. and. dry. period. (p<0.05).. Therefore,. Weather. changes. especially. during.harmattan.and.heat.period.was.found.to.triggered.migraine.attack.significantly.higher.than.during.rainy.season.(p<0.05)..The.higher.humidity.and.harmattan.winds.normally.experienced.during.dry.period.may.be.responsible.for.an.increase.in.positive.ions.or.gases.in.the.air.triggering.migraine.head.pain
