Summary
This study presents a case of intractable epilepsy with massive salivation, successfully treated with left temporal lobectomy. The findings suggest a link between hippocampal abnormalities and epileptic salivation in temporal lobe epilepsy.
Area of Science:
- Neurology
- Epileptology
- Neuroscience
Background:
- Epileptic seizures can manifest with diverse autonomic symptoms.
- Massive salivation is an uncommon but recognized ictal phenomenon.
- Temporal lobe epilepsy (TLE) is a common cause of intractable seizures.
Observation:
- A 26-year-old female patient presented with a 12-year history of intractable seizures.
- Seizures were characterized by initial upper abdominal discomfort, followed by massive salivation, loss of consciousness, and occasional generalized convulsions.
- Ictal sphenoidal EEG indicated left mesial temporal discharges, and MRI revealed left hippocampal atrophy.
Findings:
- Neuropathologic examination post-left temporal lobectomy confirmed hippocampal sclerosis.
- The patient achieved complete seizure freedom and cessation of massive salivation after surgery.
- Literature review indicates epileptic salivation can originate from various brain regions, including mesial temporal structures.
Implications:
- This case highlights the mesial temporal structures, specifically the hippocampus, as a potential origin for epileptic salivation.
- The findings suggest that abnormal hippocampal firing during TLE may trigger the frontal limbic system, leading to ictal salivation.
- Surgical intervention targeting the epileptogenic zone can effectively resolve intractable seizures and associated autonomic symptoms like massive salivation.
