68 years — that's a long time, and it makes complete sense that the older names feel more natural! The terminology was updated in 2017 by the International League Against Epilepsy (ILAE), so the change is relatively recent.
What used to be called complex partial seizures are now officially known as focal onset impaired awareness seizures. The new name is actually quite descriptive — it tells you:
- Focal onset — the seizure starts in one side of the brain
- Impaired awareness — consciousness or awareness is affected during the seizure The reason for the name changes was to make seizure types easier to understand for everyone, not just doctors. The old terms like "complex partial" didn't clearly describe what was actually happening in the brain.
Many people still use the old names though, and most doctors will know exactly what is meant either way!
