Postictal wandering localizes to temporal> extratemporal focus

Tai P. et al.  Postictal wandering (PIW) is common after temporal lobe seizures.  Neurology 2010; 74:11:924-931.

PIW occurs in 4 % of seizures, and 13 % of seizures of patients who experienced PIW (n=42 patients admitted to an epilepsy monitoring unit in Toronto.  It occurred in 9/20 with TLE and 2/22 with non TLE, and 18/186 temporal seizures, and 2/266 non temporal lobe seizures.

Literature tends to emphasize frontal seizures, contrary to these results, but may reflect selection bias of a different group.
