Neuropsychological functioning in early hydrocephalus: review from a developmental perspective

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatric Neurology

Background:

• Hydrocephalus is associated with significant neuropsychological deficits in children.
• Motor, visuoperceptual, and visuomotor functions are particularly affected.
• Corpus callosum abnormalities and ventricular enlargement contribute to cognitive impairment.

Purpose of the Study:

• To review current knowledge on the neurocognitive sequelae of hydrocephalus in children.
• To highlight the impact of hydrocephalus on cognitive domains during development.
• To identify areas requiring further investigation regarding hydrocephalus and cognition.

Main Methods:

• Literature review of medical and neuropsychological studies.
• Synthesis of existing research on neurocognitive outcomes in pediatric hydrocephalus.
• Analysis of factors influencing neuropsychological deficits.

Main Results:

• Children with hydrocephalus exhibit deficits across multiple neuropsychological domains.
• Severity and etiology of hydrocephalus influence the extent of these deficits.
• Developmental aspects of these neurocognitive impairments are not fully understood.

Conclusions:

• Further research is needed to fully explicate the core neurocognitive deficits in hydrocephalus.
• Understanding these sequelae is vital for clinicians and researchers studying the developing brain.
• Targeted investigations are required to address knowledge gaps in hydrocephalus and cognition.
