Epileptic amnesic attacks: benefit from antiepileptic drugs

Area of Science:

• Neurology
• Neuroscience
• Epileptology

Background:

• Episodic memory loss, or amnesia, can present with diverse etiologies.
• Distinguishing between different causes of amnesia is crucial for effective treatment.

Observation:

• Two elderly patients experienced recurrent, distinct episodes of amnesia.
• Electroencephalograms (EEGs) revealed frequent, independent bilateral spikes originating from temporal lobe mesiobasal structures.
• These epileptic discharges were associated with the amnesic attacks.

Findings:

• Amnesic attacks completely resolved following treatment with antiepileptic drugs.
• Neuropsychological assessments indicated specific cognitive deficits.
• One patient showed notable improvement in short-term memory post-treatment.

Implications:

• This study highlights epileptic amnesic attacks as a distinct clinical entity.
• It underscores the importance of differentiating epileptic amnesia from transient global amnesia due to similar clinical presentations.
• Effective management of temporal lobe epilepsy can alleviate amnesic symptoms and cognitive impairments.
