Insights
This study details a rare case of childhood epilepsy linked to Graves' disease (a form of hyperthyroidism). Treatment resolved the seizures, highlighting a potential connection between thyrotoxicosis and neurological events.
Area of Science:
- Pediatric Endocrinology
- Pediatric Neurology
- Clinical Case Study
Background:
- Childhood hyperthyroidism affects 5% of pediatric cases.
- Epilepsy secondary to thyrotoxicosis is exceptionally rare.
Observation:
- A four-year-old boy with Graves' disease experienced generalized tonic-clonic seizures and partial motor status epilepticus.
- Electroencephalogram (EEG) showed significant abnormalities.
Findings:
- Ablative therapy for hyperthyroidism led to normalization of EEG after five months.
- The patient became seizure-free without antiepileptic drugs, now on thyroxin replacement for hypothyroidism.
Implications:
- This case represents the first reported instance of this association in the country.
- Discusses potential pathophysiological mechanisms linking thyrotoxicosis to seizure development in children.
Abstract:
Hyperthyroidism in childhood has a relative incidence of 5%. The presence of epilepsy secondary to thyrotoxicosis is very unusual. We report the case of a four-year old boy with thyrotoxicosis due to Graves' disease. This patient developed a generalized tonic-clonic seizure followed by left sided partial motor status epilepticus. The EEG was markedly abnormal. The EEG was normal after five months of the ablative therapy. At the present time the patient is seizure-free without any antiepileptic medication and receiving replacement therapy with thyroxin due to post-ablation hypothyroidism. We conclude that this is the first reported case with this association in our country. We discuss the possible pathophysiological mechanism involved in the development of seizures in this patient.
