Insights
Childhood infectious encephalitis can lead to lasting neurocognitive deficits, affecting attention, memory, and executive functions in survivors. Comprehensive assessments are crucial for identifying children needing support.
Area of Science:
- Pediatric Neurology
- Neuroscience
- Infectious Diseases
Background:
- Infectious encephalitis in children is rare but often results in poor outcomes for survivors.
- Long-term neurocognitive consequences require thorough investigation.
Purpose of the Study:
- To prospectively describe long-term neurocognitive outcomes in children following infectious encephalitis.
- To identify specific areas of cognitive vulnerability and behavioral-emotional symptoms.
Main Methods:
- Prospective study of 59 children hospitalized for infectious encephalitis in Sweden (2011-2016).
- Neurocognitive assessments included intellectual functioning, attention, working memory, and executive functions.
- Standardized questionnaires evaluated caregiver-reported executive functioning and behavioral-emotional symptoms.
Main Results:
- Significant variability in neurocognitive outcomes and behavioral-emotional symptoms observed.
- Auditory attention, working memory, and processing speed were significantly lower than standardized means.
- Executive functions, sustained attention, and self-control were identified as areas of vulnerability.
Conclusions:
- Children surviving infectious encephalitis often experience persistent neurocognitive impairments.
- Executive functions and attention are key areas affected, necessitating targeted interventions.
- Comprehensive neurocognitive evaluations are essential for managing children post-encephalitis.
Abstract:
Infectious encephalitis in children is fairly uncommon, but unfavorable outcomes are seen in many survivors. The aim of this study was to prospectively describe the long-term neurocognitive consequences following infectious encephalitis in childhood. Children admitted to a primary and tertiary hospital in Sweden between 2011 and 2016 were asked to participate. Fifty-nine children were assessed at a median time of 18 months (IQR 18-20) after hospitalization. Follow-up included measures of intellectual functioning, attention, working memory, and executive functions. Caregiver ratings of executive functioning and behavioral - emotional symptoms were assessed with standardized questionnaires. Neurocognitive outcome and measures of executive functions and behavioral-emotional symptoms varied greatly among participants. Basic auditory attention, working memory, and mental processing speed were affected and significantly lower compared to a standardized mean. Other domains identified as areas of vulnerability included executive functions, sustained attention, and the exert of self-control. Behavioral-emotional symptoms were less common; however, somatic complaints and behaviors related to conduct problems were seen in about one-third of individuals. This study highlights the importance of a comprehensive neurocognitive examination to identify children with unfavorable outcomes.
