Abstract

Insights

Migraine with altered consciousness can mimic epilepsy, leading to misdiagnosis. This case highlights the importance of careful clinical distinction and appropriate treatment for migraine, not anti-seizure medicines.

Area of Science:

  • Neurology
  • Epileptology

Background:

  • Migraine and epilepsy are episodic neurological disorders with overlapping clinical features.
  • A comorbid relationship exists, with some migraine patients showing epileptic discharges on EEG.
  • These similarities contribute to diagnostic challenges and potential misdiagnosis.

Purpose of the Study:

  • To present a case of migraine misdiagnosed as epilepsy due to overlapping symptoms and EEG findings.
  • To emphasize the importance of accurate differential diagnosis between migraine and epilepsy.

Main Methods:

  • A case report of a 16-year-old female patient presenting with headaches and altered consciousness.
  • Long-term electroencephalogram (EEG) revealed epileptic discharges, initially leading to an epilepsy diagnosis.
  • Diagnosis was revised to migraine, with treatment including ibuprofen for acute episodes and prophylactic medications (flunarizine, amitriptyline).

Main Results:

  • The patient was initially misdiagnosed with epilepsy and unresponsive to anti-seizure medications (ASMs).
  • Following a revised diagnosis of migraine, treatment with ibuprofen and prophylactic agents resulted in complete headache resolution within one week.
  • The case demonstrated that altered consciousness during headache episodes, coupled with abnormal EEG, can be indicative of migraine.

Conclusions:

  • Altered consciousness during headache episodes, alongside abnormal EEG findings, can lead to misdiagnosis of epilepsy.
  • Clinicians must exercise caution and perform thorough differential diagnosis to distinguish between migraine and epilepsy.
  • Accurate diagnosis is crucial for effective treatment, avoiding ineffective therapies like ASMs for migraine.
