Amnesia, memory disturbances and epilepsy.The epileptic syndromes, notably the temporal lobe epilepsy, frequently include memory disturbances.  Two atypical clinical epileptic syndromes should be pointed out in the elderly: the transient epileptic amnesia and the epileptic pseudodementia.  Transient epileptic amnesia (TEA) is a subtype of medial temporal lobe epilepsy with late onset.  TEA is characterized by recurrent episodes of acute transient amnesia lasting less than one hour.  The main differential diagnosis is transient global amnesia (TGA). 
Amnesia
Amnesia, memory disturbances and epilepsy.The epileptic syndromes, notably the temporal lobe epilepsy, frequently include memory disturbances.  These memory disturbances may occur during seizures, i.e. ictal memory disturbances, or between seizures, i.e. interictal memory disturbances.  Both represent potentially reversible memory disturbances and have a treatment based on antiepileptic drugs.  Interictal memory disturbances consist of autobiographic memory disorders and long term forgetting.

Both represent potentially reversible memory disturbances and have a treatment based on antiepileptic drugs.  Conversely to TGA, TEA have a shorter duration, is recurrent but have a clear-cut response to antiepileptic drugs.  Response to antiepileptic drugs is less evident.
