Priority 5 from the Epilepsy (Canada) PSP
|UNCERTAINTY: What is the most effective testing protocol for determining causes of seizures and/or a diagnosis of epilepsy or other seizure disorders and to reduce time to diagnosis? (JLA PSP Priority 5)
|JLA question ID
|The diagnosis of epilepsy can be challenging. Seizures can have many different causes, and even after testing, the cause can be unclear. The diagnosis of epilepsy can be made by different health care providers, such as family physicians, pediatricians, or neurologists. Tests that can be used to assist with diagnosis include electroencephalography (EEG), brain imaging, or genetic testing; however,there is no standard procedure, and access to testing can vary widely across the country. There is no established protocol to determine whether a person's seizures are the result of trauma to the brain, genetic variations, or other causes, or if seizures are non-epileptic. In addition, testing may not reveal any abnormalities, and there are no clear guidelines for how to proceed when tests are inconclusive. This can lead to long delays in diagnosis, or an incorrect diagnosis, and failed attempts at treatment. More research in this area is needed, as early diagnosis of seizure disorders is critical for effective treatment.

|Original uncertainty examples
|I understand there are Epileptic Seizures and Non-Epileptic Seizures, how can a correct diagnoses be made to differentiate between the two? If a prolonged EEG is not possible are there any specific ways to distinguish between the two? ~ Are there new tools to understand the root cause of idiopathic epilepsy? ~ Can the medical community find out if an unborn fetus has epilepsy before it's born? Do the biological parents health or chromosomes have to do with the epileptic getting epilepsy? ~ It seems many places still do not consistently follow an algorithm for diagnosing-why is this? Are we diagnosing to early? not early enough?
