- Posterior cortical epilepsies originate from the occipital, parietal, or occipital border of the temporal lobe and can spread to other regions, resulting in different seizure manifestations depending on the direction of spread.
- Occipital lobe epilepsies typically involve visual symptoms like elementary hallucinations and may progress to involve other regions, resulting in non-visual symptoms. Common symptoms include visual hallucinations, eye deviation, and impaired consciousness.
- Parietal lobe epilepsies most often present with somatosensory symptoms like tingling or numbness that may spread in a jacksonian manner. Seizures can also involve body image distortions, vertigo, or language problems depending
