At several time points during the RCT, patients will be tested with the computerized test battery (for cognition; CNS VS), two additional cognitive tests and several self-report questionnaires. Testing is done prior to surgery, prior to cognitive rehabilitation (3 months), immediately after cognitive rehabilitation (6 months) and at half-year follow up (12 months post-surgery). Questionnaires on self-reported cognitive functioning, psychological symptoms (anxiety and depression), and fatigue will be administered on all assessments; the questionnaires on work status, professional functioning and community integration are administered at baseline and one-year follow-up only.
