Sri Lankan health authorities have reported a noticeable rise in migraine cases in recent weeks, attributing the trend to the ongoing hot and humid weather conditions.

Dr. Gamini Pathirana, Consultant Neurologist and Head of the Neurology and Stroke Unit at the National Hospital, stated that the current climatic conditions are a significant trigger for migraine episodes. 

He advised individuals experiencing symptoms to seek medical attention promptly, emphasizing the importance of early intervention.

Migraine is a primary headache disorder, in most cases episodic, that usually lasts 4–72 hours, accompanied by nausea, vomiting and/or photophobia and phonophobia. It is sometimes preceded by a short lasting aura of unilateral, reversable visual, sensory or other symptoms.

According to the World Health Organization (WHO), the exact cause of migraine is currently unknown but it is thought to result from the release of pain producing inflammatory substances around the nerves and blood vessels of the head.
