This study suggests paroxysmal fits in a patient with hypertension and coronary artery disease were transient ischemic attacks (TIAs) of an epileptic nature, caused by an ischemic mechanism linked to cervical stenosis.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Epileptology

Background:

  • Hypertension and coronary artery disease are significant risk factors for cerebrovascular events.
  • Transient ischemic attacks (TIAs) can manifest with diverse neurological symptoms.
  • Epileptiform seizures can arise from focal brain lesions, including those caused by ischemia.

Observation:

  • A 65-year-old male with hypertension and coronary artery disease experienced recurrent focal seizures (tonic and clonic) affecting the right upper limb and face, accompanied by transient language suspension.
  • Cerebral CT revealed a right occipital hypodensity suggestive of an old infarct.
  • Cervical angiography identified ulcerated stenosis in the left carotid artery.

Findings:

  • The clinical presentation of paroxysmal fits, characterized by focal seizures and temporary neurological deficits, was observed.

  • Imaging findings indicated underlying cerebrovascular pathology, including a likely old infarct and significant carotid stenosis.
  • The paroxysmal events were hypothesized to be transient ischemic attacks (TIAs) with an epileptic origin due to ischemia.

    • Implications:

    • This case highlights the potential for ischemic mechanisms to trigger epileptic seizures, mimicking typical TIA symptoms.
    • Accurate diagnosis requires integrating clinical presentation, neuroimaging, and vascular studies to differentiate epileptic from non-epileptic events.
    • Understanding the link between ischemia and epilepsy is crucial for effective management and prevention of recurrent cerebrovascular and neurological events.
