Studying this autobiographical amnesia, focal retrograde amnesia, or delayed onset of amnesia has been challenging because people do not always realize that they have forgotten events or periods until they have difficulty retrieving them. This memory loss can occur in people whose ability to acquire new memories is intact. Still, the persistent loss of memories of events from their past personal experiences and this autobiographical amnesia have been reported in cases where accelerated forgetting was also present. Remote memory leakħ0% of people with epileptic amnesia notice an irregular. However, they do not play a significant role in accelerated forgetting. These are essential factors when investigating patients with epilepsy in general. Research has reported that low mood and low self-esteem are associated with memory problems. One study found “subtle loss of hippocampal volume” in patients, suggesting “a more diffuse physiological basis rather than b consequence of structural damage.” Anticonvulsant medicationĪntiepileptic drugs sometimes affect memory. However, this is unlikely to be the cause, as they tend to report memory problems before starting antiepileptic medications and may experience improvement in their memory after taking them. “Alternatively, the events could lead to structural damage within the hippocampus or related structures, disrupting union in the long term.” It’s possible that a pre-existing condition affecting the temporal lobe can cause seizures and interfere with memory management. Ongoing subclinical crisis activity has exciting implications for theories of memory consolidation. Abnormal electrical activity during sleep may disrupt the memory consolidation process that generally occurs when we sleep. Seizures commonly occur upon waking, suggesting a link between amnesia and sleep. Several non-mutually exclusive hypotheses have been proposed to explain why patients experience accelerated forgetting. A recent study indicated that the acquisition of current daily events may be typical after a 30-minute delay, but that within 24 hours, patients recall significantly less information than age. It becomes apparent over the next few days and weeks. These tests typically examine the ability to store information for up to 30 minutes, but the problem of long-term accelerated forgetting is generally not noticeable at this time. Memory difficulties are one of the most common problems for people with epilepsy, and “75% of patients report persistent memory impairment.” Other studies suggest that the rate exceeds 80%, people who have had frequent attacks report three types of persistent problems with memory:
