Developmental Assessment in Neonatal Hypernatremic Dehydration Cohort at 18-30 months of Age Using DASII Score.

Developmental assessment of neonatal hypernatremic dehydration cohort was done at 18-30 mo of age using Developmental Assessment Scale for Indian Infants (DASII) score in relation to brain lesions detected on brain imaging. Long-term follow-up evaluations were performed in 45 out of initial cohort of neonatal hypernatremic dehydration and compared with 45 controls with normal sodium levels. Seven percent of infants in the study group had a delay in development at 24 mo of age. The severity of hypernatremia was strongly correlated with poor developmental outcome at 24 mo (p = 0.001). Abnormal magnetic resonance imaging patterns strongly correlated with poor developmental outcome at 24 mo (p = 0.001). Brain was found to be particularly vulnerable to the effects of hypernatremic dehydration in neonates with brain imaging showing brain changes which presented with developmental delay on follow-up. Motor score was found to be more severely affected than mental facet using DASII score.
