Being in the presence of someone having a seizure can be an unsettling experience for an observer seeing it for the first time. But with thousands of Canadians affected by epilepsy, it鈥檚 not that uncommon an experience 鈥� and it鈥檚 important to know the facts.

Tonight, March 16,听as part of Brain Awareness Week, Dr. Michael Esser, the William Dennis Chair in Pediatric Epilepsy Research, will be presenting a public lecture on 鈥淓pilepsy 鈥� Facts, Fiction and Reality鈥� in the Potter Auditorium of the Rowe Building at 7 p.m. And sadly, he says, there are a lot of fictions out there.

For instance, have you heard that someone can swallow their tongue while in the midst of seizure? Not true 鈥� it鈥檚 physiologically impossible to do so. And that you should put an object or your fingers in the mouth of someone suffering from a seizure? That鈥檚 downright dangerous to everyone involved.

But that pales in comparison to attitudes in the developing world, where over 80 per cent of global epilepsy cases occur. There, people who suffer from epilepsy can often be seen as intellectually impaired, violent or dangerous, when they鈥檙e generally none of the sort.

鈥淚鈥檓 hoping that people in attendance can not only gain a better awareness of the condition, but will learn to reject some of the stigmas surrounding it,鈥� says Dr. Esser.

Brain Awareness Week Activities听continue until March 19 with daily events: - Wednesday March 17: children's activities at the Discovery Centre, 11 a.m. - 3 p.m. - Thursday March 18: public lecture by Cornelius Borck, University of Lubeck, Germany:听"Mind the Gap, The Neurosciences and their Determination to Explain the Human"; 7 p.m., Alumni Hall, University of King's College. - Friday March 19: Graham Goddard Lecture by Jean-Pierre Julien, Universite Laval, "ALS: Recent developments in genetics, mouse models and immunotherapy"; 3:30 p.m., room 4263, Life Sciences Centre, Dalhousie.

Epilepsy affects approximately 0.6 per cent of Canadians, and about 50 million people worldwide. In Canada alone there are approximately 15-16,000 new cases diagnosed each year. Contrary to popular belief it鈥檚 not a disease in and of itself; it鈥檚 a symptom of an underlying neurological condition. And while cases among newborns are decreasing, the incidence among Canadians age 65 and older are on the rise.

鈥淲e know some of the causes of epilepsy 鈥� things like infections, brain injuries, trauma, strokes, says Dr. Esser. 鈥淏ut in a large portion of cases, something like 50 or 60 per cent, we just don鈥檛 know the cause.鈥�

He notes that Halifax is actually a hot spot for epilepsy research, with talented researchers working in clinical epidemiology, neuroimaging and neurodiagnostics and basic science research. Dr. Esser鈥檚 work falls into the overlap of the different categories, which he says is a huge asset.

鈥淚t gives me the opportunity to see the clinical condition, and then take that information and knowledge into a laboratory setting.鈥澨�
