When Matthew Collins first went to doctors with debilitating symptoms including “thunderclap” headaches, seizures, temporary blindness, and then a stroke, he was dismissed as a worrier.

“When I was in the stroke ward I kept telling them I felt I was getting worse, and they said it was just all in my head,” Mr Collins said. “They just said I was anxious.”
