Focal cognitive seizure Focal cognitive seizure with memory impairment 2020-03-14T08:36:57Z Amnestic seizure www.epilepsydiagnosis.org focuses on anterograde amnesia during the seizure. Both ictal retrograde and anterograde amnesia have been included here given that they are well studied as ictal manifestations of 'transient epileptic amnesia'. The clinical onset of these seizures is defined by questions indicating ictal retrograde amnesia, often because of disorientation. Ictal anterograde amnesia is incomplete in many individuals with transient epileptic amnesia: half at least partly recall 'not being able to remember' during seizures. A focal cognitive seizure characterized by transient memory impairment as the initial semiological manifestation whilst other cognitive functions and awareness are preserved at seizure onset. The memory impairment may be an inability to recall events occurring prior to the seizure (retrograde amnesia), or failure to encode new memories for events occurring during the seizure (anterograde amnesia).
