title: Seizure disorders in patients with brain tumors.
abstract: The aim of this study was to analyze the clinical data of patients with epileptic seizures and diagnosed brain tumors. Analysis included 711 patients with primary and secondary brain tumors. 165 (23%) patients had experienced at least one seizure before tumor diagnosis. The mean time from the first epileptic seizure to tumor diagnosis was 16 months. The patient's age, location and pathology of tumor were associated with occurrence of seizures. Seizures were more common in patients aged 30-50 years. Tumors involving the frontal, frontoparietal, temporal and frontotemporal lobes were associated with occurrence of seizures. According to the histological diagnosis, patients with mixed gliomas (62%), oligodendrogliomas (53%) and astrocytomas (42%) experienced seizures most frequently.
