Etiology
- Many.
Syndromic:
Tumour:
Microscopic
Features:[4]
- Mesial temporal sclerosis = scarring of the medial temporal lobe.
- Involves: hippocampus, parahippocampal gyrus and amygdala.
- Hippocampus: CA1 and CA4 affected.
- Involves: hippocampus, parahippocampal gyrus and amygdala.
Notes:
- Changes in CA1 & CA4 of the hippocampus - DDx:
- Epilepsy.
- Dementia.
Sudden unexpected death in epilepsy
- Abbreviated SUDEP.

- Negative autopsy.
- History of epilepsy.
