The aim of this systematic review is to compare neurocognitive disease, psychiatric symptoms, and structural brain changes in patients with Cushing's disease (CD)\/CS and those with non\u2010functioning pituitary adenoma (NFPA), both before and after surgical treatment, and in comparison to healthy controls. Possible predictors of persistent neurocognitive symptoms and reduced quality of life in patients with CS are highlighted. We reviewed the English literature published in Medline\/Pubmed until 2021 to identify eligible studies. This systematic review was registered on Prospero and reported following the PRISMA statement guidelines. The initial literature search yielded 1772 articles, of which 1096 articles remained after removing duplicates. After excluding case reports, animal studies, narrative reviews, comparative reviews, and articles not in English, 86 papers underwent full\u2010text review. Studies eligible for inclusion met the following criteria: (1) described patients with CD\/CS, (2) reports of psychiatric symptoms, (3) written in English or with available English translation, and (4) published in a peer\u2010reviewed journal. The full\u2010text review process identified 40 eligible studies. The 40 studies included a total of 2603 participants with CD or CS, with 45.2% of the total participants having CD. The majority of studies were case\u2013control studies and used validated questionnaires such as the Beck's Depression Index, Trail Making Test, Hospital Anxiety and Depression Scale, and Cushing Quality of Life for screening. Compared to NFPA controls, patients with CD who had greater baseline serum cortisol levels had worse cognitive function, even after surgical remission. This suggests a possible association between greater baseline cortisol levels in patients with CS and persistent cognitive impairment. A longer duration of uncontrolled CS was associated with worse cognitive function; however, there was no association found between the length of remission and memory. Overall brain volume was increased in patients in remission from CD compared to active disease. However, temporal and frontal lobe volumes did not recover to normal volumes. Patients with CS experience neurocognitive dysfunction, psychiatric disorders, and diminished quality of life, and symptoms may persist after curative surgery. We found several factors consistently associated with persistent cognitive and neuropsychiatric symptoms in patients with CS including higher pre\u2010operatively baseline cortisol production, longer duration of disease, frontal and temporal lobe atrophy, and the presence of cognitive and neuropsychiatric symptoms at baseline. Larger prospective studies are required to validate these findings.<\/jats:p>","DOI":"10.1111\/jne.13466","type":"journal-article","created":{"date-parts":[[2024,11,7]],"date-time":"2024-11-07T00:53:47Z","timestamp":1730940827000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Cognitive
