Brief Summary

Atypical presentations in epilepsy may include confusion status, acute maniac or delirious condition, loss of cognitive ability such as speech, interaction skills, or other praxis. Current diagnosis of epilepsy did not address on definition of seizure. The new insights of seizure semiology and their treatment response, suggest the screen tool and diagnostic criteria of epilepsy can be revised. In this study, we have two aims. The first aim is to develop a screening questionnaire by adding new semiology of epilepsy, including abnormality in psychiatry, cognition, and sleep, and to test its accuracy. The second aim is to evaluate the benefits in cognition of anti-epileptic drug intervention in participants with positive screening results.

Outcome Measures

Primary Outcomes (1)

  • Mini-Mental State Examination

    The Mini-Mental State Examination is a common analysis of cognitive function, with a score range from 0 to 30, and higher score indicates a better performance of cognition. We hypothesized that differences after ASM intervention will have a difference score of 4 in comparison to the observational group.

    12 weeks

Secondary Outcomes (2)

  • Pattern changes in electroencephalography

    12 weeks

  • Neuropsychiatric Inventory Questionnaire

    12 weeks

Study Arms (2)

Anti-seizure medication

EXPERIMENTAL

The intervention group will receive anti-epileptic drug treatment according to the guideline of American Epilepsy Society 15 for 12 weeks. The recommended regimens include zonisamide, lamotrigine, or levetiracetam at the minimal therapeutic doses (zonisamide 100mg twice daily, levetiracetam 500mg twice daily, lamotrigine 50mg twice daily), and the choices depend on tolerability of the participants and contraindications (allergy to any drugs, or allergy to sulphonamides in zonisamide users). The participants will be followed every 4 weeks.

Drug: Zonisamide 100mgDrug: Levetiracetam 500mgDrug: LamoTRIgine 50mg

Observation

NO INTERVENTION

The participants will be followed every 4 weeks without anti-seizure medication.

Interventions

Only one ASM will be used. The drug choice depends on patients tolerance and basic condition. Twice daily
