Neuropsychiatric Symptoms After Brain Tumor Resection in Children and Adolescents: A Scoping Review.

BACKGROUND: Brain tumors are one of the most common solid tumors in pediatric populations, with their treatments having significant neuropsychiatric impact. OBJECTIVE: The objective of this study was to review the literature on neuropsychiatric sequelae after surgical resection of brain tumors in children and adolescents. METHODS: Using a scoping method, we reviewed empirical articles describing pediatric patients with brain tumors who underwent partial or total resection and examined major neuropsychiatric domains postoperatively over time. RESULTS: The initial search yielded 15,543 articles. After duplicate removal, abstract screening, and review, 44 articles were included. Cognitive deficits were the most widely studied outcomes and found to be associated with tumor location, operative variables, perioperative complications, treatment types, and psychosocial factors. Cerebellar mutism, or posterior fossa syndrome, commonly co-occurred with emotional and behavioral dysregulation after posterior fossa resections. Depression, anxiety, and somatization were frequently grouped together as "distress," with higher rates among pediatric patients with brain tumor than among healthy peers. Problematic school behaviors, antisocial, and attention-deficit traits were increased; however, several other behaviors (e.g., risky sexual behaviors, substance use) were equal or lower when compared to peers. Posttraumatic stress disorder was highly prevalent and often interfered with social functioning. Delirium, eating disorders, and longer-term outcomes received inadequate attention. CONCLUSION: Identifying risk factors of neuropsychiatric sequelae and their impact after pediatric brain tumor resection is important for prognostication and the development of tailored management strategies for these children and adolescents.

Examining the Neuropsychiatric Sequelae Postsurgical Resection of Adult Brain Tumors Through a Scoping Review.

BACKGROUND: Improving brain tumor survival rates have drawn increasing focus on neuropsychiatric and psychological outcomes. OBJECTIVE: This review characterizes the literature on neuropsychiatric sequelae after neurosurgical resection of adult brain tumors. METHODS: Using a scoping method, we reviewed articles describing patients with adult brain tumor who underwent partial or total brain resection and examined major neuropsychiatric domains after intervention. RESULTS: The initial search yielded 9903 articles. After duplicate removal, abstract screening, review, and hand searching, 81 articles were found: 63 empirical and 18 nonempirical. Most articles centered on survivorship within the first year. Cognition was most widely studied with a transient worsening during the first month and usually recovery or improvement thereafter. Depression increased in frequency during survivorship and was associated with frontotemporal location, time to survival, quality of life, cognitive and physical parameters, and functional status. Anxiety, independent of depression, related to tumor histology and grading and had a weaker association with cognition and quality of life. Obsessive-compulsive symptoms, psychosis, mania, and delirium received little attention. Most studies did not include preoperative neuropsychiatric assessment, and treatment was poorly addressed. CONCLUSION: This review highlights key gaps, including preoperative and postoperative neuropsychiatric assessment and a short follow-up. A better understanding of postresection neuropsychiatric outcomes can inform our ability to prognosticate and tailor management for patients at risk for these life-impairing conditions.
