This controlled prospective observational study will include two groups with a total of 84 participants. A total of 42 patients diagnosed with melanoma, referred to treatment with ICI will be enrolled in the study and examined prior to treatment with ICI (baseline), at eight weeks following baseline (T2), at 24 weeks following baseline (T3) and 12 weeks after treatment completed (T4). A total of 42 gender- and age- matched healthy controls will be included and assessed at similar time points. Assessments will include a battery of neuropsychological tests, questionnaires, blood samples, and Magnetic Resonance Imaging (MRI).
The main objectives of the study are to investigate:
1. Changes in cognitive functions over the course of treatment with ICIs.
2. Possible associations between changes in cognitive function and immune markers during and following ICI treatment.
3. Possible associations between changes in cognitive function and changes in brain morphology.
4. Changes over time in other possible adverse effects of ICI treatment, including psychological distress, sleep disturbances, and fatigue.
