Neuropsychological function in children following admission to paediatric intensive care: a pilot investigation

Area of Science:

• Pediatric critical care medicine
• Neuropsychology
• Child psychology

Background:

• Neuropsychological outcomes after severe pediatric illness are not well understood.
• Acute severe pediatric illness may impact cognitive functions, including memory.
• Potential links between cognitive deficits and subsequent psychiatric issues warrant investigation.

Purpose of the Study:

• To explore the effects of severe acute pediatric illness on memory function.
• To investigate associations between memory deficits and psychiatric sequelae in children.
• To assess neuropsychological status in children post-pediatric intensive care unit (PICU) discharge.

Main Methods:

• A case-control pilot study comparing children recently discharged from the PICU with healthy, age- and sex-matched controls.
• Neuropsychological assessments included the CANTAB battery for visual-spatial memory, Children Memory Scale for verbal memory, and Wechsler Abbreviated Scale of Intelligence for IQ.
• Emotional and behavioral functioning were evaluated using the Strengths and Difficulties Questionnaire and Impact of Event Scales.

Main Results:

• Children discharged from the PICU demonstrated significantly poorer performance in spatial working memory, sustained attention, and verbal memory (word pair learning, delayed recognition).
• Septic illness was specifically linked to deficits in pattern recognition memory.
• The PICU group exhibited significant correlations between cognitive performance and emotional/behavioral scores.

Conclusions:

• Children recovering from severe acute pediatric illness exhibit impairments in memory and attention.
• A specific memory deficit was observed in children with septic illness.
• Findings suggest a link between memory anomalies and emotional/behavioral problems, necessitating further research in larger cohorts.
