Cognitive deficits and psychopathological symptoms among children with medulloblastoma. (11th September 2018) - Szentes, Annamária
Abstract: Children with medulloblastoma (MB) are predisposed for negative cognitive sequela, which has been widely identified in this population. The purpose of the present study was to explore cognitive deficits and psychopathological symptoms and analyse their relation among MB survivors. The Wechsler Intelligence Scale for Children and the Mini International Neuropsychiatric Interview (MINI‐KID) was administered to 34 MB survivors to measure cognitive functioning and psychopathological symptoms. The MB survivors had lower global IQ (86.41 [79.70–93.13]) compared with the control population mean. We found impaired functioning in all IQ subscales in the MB survivors group, of which processing speed (84.15 [77.71–90.58]) was the most affected. Higher radiation dose and high‐dose chemotherapy with stem cell rescue were significantly associated factors for lowered global IQ, while age at diagnosis, sex and time period from diagnosis were not significantly associated. Compulsive disorder, generalised anxiety, separation anxiety and posttraumatic stress disorder were significantly more prevalent in the MB survivor group than a group of 46 control participants. No correlation was found between the cognitive deficits and the psychopathological symptoms. Our results identify that MB survivors suffer from cognitive and psychopathological impairments, and these could exist independently from each other.
