Medical History and Seizures
The inquest heard that Korchinski-Paquet, a woman of Ukrainian, Black and Indigenous ancestry, had a long history of seizures due to epilepsy. According to an agreed narrative read at the inquest, her seizures were often followed by symptoms such as "confusion, irritability, physically and verbally abusive behaviour and episodic amnesia."
Dr. Julien Hébert, a neurologist specializing in epilepsy who reviewed Korchinski-Paquet’s records, testified that she showed patterns of behaviour consistent with postictal delirium or psychosis on several occasions. These are mental states that can occur after seizures. Postictal psychosis involves a disconnect from reality, while postictal delirium involves an altered state of awareness and confusion.
On the morning of May 27, 2020, Korchinski-Paquet experienced two seizures. Hours later, police were called to the apartment over a "rapidly developing and violent family disturbance that involved knives," coroner’s counsel said. Korchinski-Paquet herself made three of the five calls to police. A neurologist who listened to the recordings testified that she sounded distressed and repetitive, as though she could not remember her previous calls. Less than half an hour later, she fell from the 24th floor.
