Abstract:
Meningiomas are the most common primary brain tumors accounting for about 30% of all brain tumors. The vast majority of meningiomas are slow-growing and of benign histopathology rendering them curable by surgery alone. Symptomatic lesions depend on the location with signs of mass effect or neurological deficits. Seizures are the presenting symptoms in approximately 30% of cases, which negatively affect quality of life, limit independence, impair cognitive functioning, as well as increase the risk for psychiatric comorbidities including depression. Although surgical resection may offer seizure freedom in 60-90% of meningiomas, seizures persist after surgical resection in approximately 12-19% of patients. Anti-seizure medications (ASMs) are employed in management, however, are limited by adverse neurocognitive side-effects and inefficacy in some patients. The potential predictors of pre- and post-operative seizures in meningioma patients have been identified in the literature. Understanding various factors associated with seizure likelihood in meningioma patients can help guide more effective seizure control and allow for better determination of risk before and after surgery.
Insights
Meningiomas, common brain tumors, often cause seizures impacting quality of life. Understanding seizure predictors aids better management and surgical outcomes for patients.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Background:
- Meningiomas are the most common primary brain tumors, comprising approximately 30% of all intracranial neoplasms.
- While often benign and surgically curable, meningiomas can cause significant symptoms, including seizures, affecting patient quality of life.
- Seizures occur in about 30% of meningioma cases, persisting post-surgery in 12-19% despite treatment.
Purpose of the Study:
- To identify predictors of pre- and post-operative seizures in meningioma patients.
- To enhance understanding of factors influencing seizure likelihood in this population.
- To guide more effective seizure control strategies and risk assessment before and after surgical intervention.
Main Methods:
- Literature review of studies identifying potential predictors of seizures in meningioma patients.
- Analysis of factors associated with pre-operative and post-operative seizure occurrence.
- Synthesis of findings to inform clinical management and patient counseling.
Main Results:
- Established predictors for seizures in meningioma patients have been identified in existing literature.
- Understanding these predictors is crucial for managing seizure frequency and severity.
- Factors influencing seizure likelihood require further investigation for comprehensive patient care.
Conclusions:
- Identifying seizure predictors in meningioma patients is vital for improving patient outcomes.
- Effective seizure management strategies can be developed by understanding pre- and post-operative factors.
- Further research into seizure likelihood factors will aid in personalized treatment approaches for meningioma patients.
