Cataplexy in association with meningiomas.

Summary
Meningiomas, tumors in the brain, can cause cataleptic attacks or atonic seizures. This study suggests considering meningiomas as a cause, especially in patients over 50, due to specific seizure patterns.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Background:
- Cataleptic attacks and atonic seizures are associated with frontal lobe lesions.
- Meningiomas are tumors that can arise in the brain and potentially cause neurological symptoms.
Purpose of the Study:
- To investigate the relationship between meningiomas and cataleptic attacks.
- To identify potential clinical features and etiological factors associated with meningioma-induced seizures.
Main Methods:
- Retrospective analysis of five new cases with frontal or parietal meningiomas presenting with cataleptic attacks.
- Review of a consecutive case series of 66 intracranial meningiomas to identify additional cases with similar symptoms.
Main Results:
- Three new cases involved frontal meningiomas, and two involved parietal meningiomas.
- Cataleptic attacks preceded tumor removal in three of the five reported cases.
- Two patients with parietal convexity meningiomas experienced cataleptic attacks.
Conclusions:
- While cataleptic attacks in individuals over 50 are often vascular, meningiomas (frontal or parietal) should be considered.
- The study suggests that 'weak' epileptic discharges activating motor inhibitory pathways may cause these seizures in meningioma patients.
