Differential diagnosis A differential diagnosis should include: *Thrombosis of the basilar artery *Cardioembolic stroke *Complex partial seizures *Frontal lobe epilepsy *Lacunar syndromes *Migraine variants *Posterior cerebral artery stroke *Syncope and related paroxysmal spells *Temporal lobe epilepsy If the event lasts less than one hour,<unk>  epileptic amnesia (TEA) might be implicated. If the condition lasts longer than 24 hours, it is not considered<unk>  by definition. A diagnostic investigation would then probably focus on some form of undetected ischemic attack or cranial bleed.
