Maternal Multiple Sclerosis and Offspring’s Developmental and Behavioral Profile: A Case-control Study
Year: 2025
Type: article
Study design: Observational Study
Abstract: INTRODUCTION: Maternal chronic immune and inflammatory conditions may predispose newborns to atypical developmental trajectories, identifying pregnancy as a key period for the etiopathogenesis of neurodevelopmental disorders. The possible long-term impact of maternal multiple sclerosis (MS) on the offspring's cognitive and behavioral development and its pharmacological treatment during pregnancy is mostly unknown. This study aims to delineate the cognitive and behavioral profile of offsprings exposed to maternal MS, untreated or treated with Natalizumab throughout pregnancy, in comparison to a control group. METHODS: We retrospectively enrolled 39 children (23 males; 16 females; mean age 45.82 ± 35.46 months) exposed to maternal MS, untreated or treated with Natalizumab throughout pregnancy, and 36 children (24 males; 12 females, mean age 38.03 ± 21.52 months) of healthy mothers. All offspring underwent a standardized evaluation of their intellectual or developmental quotient, adaptive functioning, and behavioral issues, including symptoms of autism. RESULTS: The clinical profile of the included offspring was characterized by an adequate cognitive profile and a good level of adaptive skills (MS offspring: Griffiths III mean total DQ (N = 30) 114.57; WISC-IV mean Full IQs (N= 9) 115.44; mean ABAS GAC 97.28/Control offspring: Griffiths III mean total DQ (N = 31) 105.42; WISC-IV mean Full IQs (N= 4) 119.25 ± 11.32; mean ABAS GAC 97.82 ± 21.4). Furthermore, no significant behavioural problems or autism symptoms emerged in the entire group, regardless of MS treatment. CONCLUSION: Offspring's developmental and behavioral phenotypes do not appear to be influenced by maternal treatment with Natalizumab until late pregnancy, nor by maternal variables directly related to MS (age at the time of MS diagnosis, disease duration, and severity).
