Objective: Cushing’s disease (CD) and acromegaly (AC) are associated with psychological and psychiatric problems. Both pathologies cause a severe impairment in quality of life (QoL) that can persist even if biochemical remission and cure are achieved. The aim of the study was to investigate the influence of the current disease status (remission vs. no remission) on neurocognitive function and QoL in treated CD and AC patients. The second objective was to determine predictive factors (e.g. demographic, clinical, neurosurgical, endocrinological) that determine postoperative neuropsychological function and QoL

Methods: 25 CD and 37 AC patients underwent neuropsychological testing. The SF-36, SCL-90-R and AcroQoL questionnaires were applied to assess QoL. CD patients underwent a dexamethasone-suppression-test, IGF-1 levels were assessed in AC patients to determine the current disease status. The results were compared with 28 sex-, education- and age-matched healthy controls (HC).

Results: Limitations in QoL evaluated for both pathologies compared to the HC were more pronounced than neurocognitive decrease. This finding was independent of the current status of disease (remission vs. no remission). Regression analyses revealed age at operation and comorbidities to predict postoperative outcome in AC, while persistent hypocortisolism and the amount of operations are best associated with neurocognition and QoL in CD.

Conclusions: In both pathologies, the current status of disease does not play the major role in postoperative outcome. A possible explanation might be the considerably improved endocrinopathy after treatment, even if no actual cure is achieved. Obviously, this leads to an assimilation of disease status and perceived QoL.
