Study Arms:
- Study group experimental (Type: EXPERIMENTAL): 24 female patients aged 18 years or older undergoing urogynecological or breast cancer surgery; the patients are recommended to perform the RehaCom® training modules 'Topological Memory (MEMO)' and 'Divided Attention 2 (GEA2)' daily during inpatient hospital stay, and at least three times a week for 30 to 60 minutes until month 3.
- Study group active comparator (Type: ACTIVE_COMPARATOR): 24 female patients aged 18 years or older undergoing urogynecological or breast cancer surgery; the patients are recommended to perform the RehaCom® training modules 'Topological Memory (MEMO)' and 'Working memory (WOME)' daily during inpatient hospital stay, and at least three times a week for 30 to 60 minutes until month 3.
- Control group (Type: NO_INTERVENTION): 48 female control subjects aged 18 years or older (24 without surgery, 24 with urogynecological or breast cancer surgery) with a similar health status and age as the study group patients (similar distribution in the American Society of Anaesthesiologists physical status classification and relevant co-morbidities, e.g. diabetes, coronary artery disease, hypertension and hyperlipidemia). The patients are analyzed to correct for learning effects of the cognitive assessment testings in the study groups.

Based on this trial design, predict the completion outcome and termination type (if applicable).
