The use of neuropsychological data to detect altered neurological functioning in a child with myelomeningocele
1University of Arkansas for Medical Sciences, Department of Pediatrics, Little Rock 72202.
Insights
This case study highlights how neuropsychological testing identified cognitive changes in a child with spina bifida. Early evaluation and psychometric data are crucial for diagnosing neurological issues in high-risk pediatric patients.
Area of Science:
- Neuropsychology
- Pediatric Neurology
- Developmental Neuroscience
Background:
- Children with myelomeningocele (a form of spina bifida) often exhibit atypical cognitive patterns.
- Establishing baseline neuropsychological functioning is vital for monitoring neurological health in this population.
Observation:
- A patient with a history of myelomeningocele and a ventriculoperitoneal shunt presented with a significant discrepancy between verbal and nonverbal IQ scores.
- Neuropsychological evaluation revealed depressed memory skills and psychomotor slowing, suggesting a decline in cognitive function.
- Magnetic resonance imaging identified a left frontoparietal brain mass.
Findings:
- Surgical removal of the brain mass led to improvements in nonverbal intelligence, psychomotor speed, and information processing.
- Neuropsychological instruments demonstrated sensitivity in detecting neurological alterations.
- Follow-up testing confirmed cognitive recovery post-intervention.
Implications:
- This case underscores the clinical utility of psychometric data in the diagnostic workup of neurologically compromised children.
- Emphasizes the importance of baseline neuropsychological assessments for early detection of cognitive deficits.
- Highlights the potential for recovery with timely medical and surgical interventions.
Abstract:
Although children with myelomeningocele often display atypical patterns on psychometric testing, this case study demonstrates the sensitivity of neuropsychological instruments to detect altered neurological functioning in a patient with spina bifida. The subject had a history of myelomeningocele at the lumbosacral level and placement of a ventriculoperitoneal shunt. During a routine neuropsychological evaluation, a 44-point discrepancy between his verbal (verbal IQ = 98) and nonverbal abilities (performance IQ = 54) on the Wechsler Intelligence for Children-Revised was found. In comparison to high average academic achievement, test findings suggested depressed memory skills and extreme slowing in psychomotor speed. A pattern of acute decline in overall cognitive functioning was suggested. Magnetic resonance imaging revealed a left frontoparietal brain mass, which was surgically removed. Follow-up neuropsychological testing 9 months postsurgery indicated an increase in nonverbal intelligence with improved psychomotor speed and information processing. This case study illustrates the importance of obtaining baseline evaluations in this neurologically high-risk population as well as the clinical usefulness of psychometric data in diagnostic workups.
