Abstract

Introduction: Cognitive impairment appears in almost all patients with glial tumors during the course of this neuro-oncological disease. There are various reasons for this in regards to the glial tumor: grade of malignancy, rate of growth, molecular nature, mass effect, and presence of perifocal edema. But these factors do not always correlate with the degree of patient’s cognitive impairment. The present study’s aim is to account for age as a factor in the occurrence of cognitive decline in patients with glial tumors.
Materials and methods: The study includes thirty two patients diagnosed with a glial tumor, treated operatively in the Neurosurgery Clinic of University hospital „St. Marina“ in Varna between 2019 and 2022 year. Twenty nine of those patients are diagnosed with glioblastoma, two are diagnosed with diffuse astrocytoma and one with astrocytoma grade 3 according to WHO. The mean age of the patients is 58.4 ± 11.4 years. The youngest patient is 25 years old and the oldest is 78 years old. Preoperatively, all patients are subjected to a series of cognitive tests.
Results: From the studied sample, patients diagnosed with glioblastoma showed lower cognitive scores compared to the patients diagnosed with other glial tumors. Patients diagnosed with glioblastoma are significantly older than the patients diagnosed with other glial tumors.
Conclusion: The older age of patients affected by glioblastoma may be an additional reason beside tumor factors for lower cognitive test outcome compared to patients affected by lower-grade gliomas.
