Could annual dramatic shifts in day/night patterns in the Arctic have an effect on seizures? One researcher went looking for answers – and found more than he bargained for. His research revealed a public health crisis in one of the wealthiest countries in the world, highlighting the needs of geographically isolated communities and Indigenous peoples. (He also found intriguing results to his original question.)  Dr. Marcus Ng reviewed 11 years of data on emergency evacuations from the Kivalliq region of northern Canada. There, anyone who has seizures that last more than 5 minutes - an emergency condition known as status epilepticus - is helicoptered to a single hospital in Winnipeg, Manitoba. Dr. Ng wondered if the frequency of evacuations changed as the seasons changed. Were people more likely to have seizures in the 24-hour darkness of winter, the 24-hour daylight of summer, or somewhere in between? He found that the people of the Kivalliq region had the highest reported incidence of status epilepticus in the world, far higher than Canada's overall estimates. His research also revealed the barriers to timely care faced by this population.  This episode was reported and produced by Nancy Volkers.
