Attachment insecurity in infants with infantile spasms: Maternal anxiety and sadness, and infant's temperament outweigh disease severity.

OBJECTIVE: The aim of this study was to investigate attachment behavior in a population of infants with infantile spasms (ISs) using the Strange Situation Procedure (SSP) and to explore factors associated with the infants' attachment behavior. METHODS: The SSP was assessed in a population of 29 children with ISs during the second year of life. In mothers, we assessed anxiety, depression, maternal emotions, and perception of the temperament of the child, and sociodemographic characteristics. In children, we assessed epilepsy characteristics, response to antiepileptic drugs (AEDs) at the time of the SSP, and the child's outcome at 3 years of age, in terms of intellectual disability (ID), and autism spectrum disorder (ASD). RESULTS: Insecure attachment was higher than in the general population (68% versus 32%). It was associated with maternal anxiety, sadness, and maternal representation of the child at 12 months but with none of the child characteristics including ID, ASD, response to AEDs, or ISs etiology. SIGNIFICANCE: Nonspecific dimensions were more important than disease characteristics for the infants' attachment behavior. In conclusion, we propose that interventions targeting mother-child interaction could prevent attachment insecurity and the developmental consequences of early epilepsy.
