Neurological Morbidity In A 22q11.2 Deletion Children Population

We describe a high frequency of neuropsychiatric disorders in 22q11.2 deletion syndrome (22q11.2DS). Medical records of 71 children with 22q11.2SD into our database were reviewed. The mean age follow-up was 8.8 (SD 10.2) years, 37 boys (52.1%). The average age at diagnosis was 30.5 (SD ±74.2) months (significant differences in children with/without congenital heart disease 0.7 vs 32.64 months). In infant period (0-2 years) the neurological morbidity were motor coordination disorders (86.6%), epileptic disorders (60%) and microcephaly (44.4%). In the preschool (2-5 years) and school stage, the most frequent morbidity were childhood neurodevelopmental as disorders global delay in psychomotor development (98%), communication disorder (89.4%) and autism spectrum disorder (16%). In the school stage, learning disorders (96.6%), attention deficit hyperactivity disorder (86.4%) and cognitive disability 60%. Towards adolescence (10-18 years) the spectrum of schizophrenia and other psychotic disorders (18.5%) became evident and type parkinsonian motor disorders (11.1%). Conclusions: The variability of neuropsychiatric involvement in 22q11.2SD is age dependent. A systematic search for them is required for early treatment and rehabilitation. 1.-Van den Bree M, Challenger A, Cuthbert A, Ayllon MA, Clarke A, et al.
