The First Seizure clinic at Kingston Health Sciences Centre run by Dr. Winston provides rapid neurological assessment of adult patients presenting with a first suspected seizure to determine if the event was a seizure or a mimic (such as vasovagal syncope), and if it was a seizure to perform risk stratification and determine if treatment is recommended.
Referrals
Referrals are primarily from Emergency Departments or Family Physicians across South-Eastern Ontario. Given a common clinical presentation and large catchment area, only referrals meeting the criteria below will be seen as a priority. Other referrals will be redirected as appropriate to routine epilepsy or general neurology.
Note that patients require an EEG before they will be booked in the clinic. To book an EEG at KHSC, please see https://kingstonhsc.ca/healthcare-providers/booking-eeg-services-physicians
Brain imaging should also be performed (at least a CT brain, but ideally also an MRI brain).
Criteria For Referral
Adult patient (18 years or over)
|
If younger than 18 years, refer to pediatric neurology or general pediatrics
|
First episode of suspected seizure
|
If recurrent events, then refer to epilepsy or general neurology; given wait times consider discussing with on call neurology regarding starting treatment
|
Without access to a neurologist
|
If patient has already been assessed by neurology, or has a neurologist, request should be directed to that neurologist
|
Not provoked
|
The clinic does not review alcohol-withdrawal or drug-induced seizures
|
Not currently on or starting treatment
|
The aim of the clinic is to determine if treatment is required, so if a clear etiology requiring treatment is present (e.g. seizure from stroke) then refer to epilepsy after starting treatment
|
Referrals to the clinic can be directed to the central neurology intake fax at 613-548-6137.
Vasovagal Syncope
Historically, around a third of referrals have a diagnosis other than seizure. The most common is vasovagal syncope from cerebral hypoperfusion. A prodrome of lightheadness, feeling hot or cold, diaphoresis, palpitation, closing in of vision or pallor with a brief loss of consciousness and rapid recovery are suggestive of this diagnosis. A few myoclonic jerks may occur but are not sustained. Evaluation should include postural BP and ECG.
