About

The goal of modern neurooncological surgery is to obtain maximum tumor resection while preserving neurological function. Parietal lobe gliomas often cause attention deficits (hemineglect) that are difficult to differentiate from other deficits. This study aims to evaluate the extent and variation over time of visuo-spatial deficits in patients undergoing surgical removal of parietal lobe gliomas. This will help characterize the cognitive profile of these patients to identify personalized treatment and rehabilitation paths.

Full description

This is a single-centre, prospective, cross-sectional, observational study involving 40 patients with high- and low-grade parietal lobe glioma. The study investigates the prevalence of subjects who show a performance in cognitive visuo-spatial tests below the cut-off of the normative sample. It evaluates associations with patient-reported outcome measures (ADL, IADL), clinical-demographic aspects, radiological data (MRI), and histological/molecular data. Assessments occur at screening (pre-surgery), and at follow-up visits (3-4 months and 6 months post-surgery). Neuropsychological tests include Line Bisection, Bell and Letter Cancellation, Reading test, Apple Cancellation, and Fluff test.
