[IQ in hydrocephalus and myelomeningocele. Implications of surgical treatment]
Insights
Early hydrocephalus treatment in myelomeningocele patients improves cognitive outcomes. Optimal surgical timing and minimizing shunt complications like infections and reoperations are crucial for better IQ scores in children with myelomeningocele and hydrocephalus.
Area of Science:
- Neuroscience
- Pediatric Neurology
- Developmental Pediatrics
Context:
- Myelomeningocele affects 0.4 per 1000 neonates.
- Hydrocephalus is a common comorbidity, present in 85-90% of cases.
- Cognitive outcomes in this population are underreported in scientific literature.
Purpose:
- To investigate the correlation between intellectual quotient (IQ) and various factors in children with treated myelomeningocele and hydrocephalus.
- To identify key clinical parameters influencing cognitive development in this cohort.
Summary:
- A study of 45 children (mean age 7.5 years) with treated myelomeningocele and hydrocephalus assessed IQ in relation to motor function, shunt surgery timing, revisions, infections, and head circumference.
- Cognitive function correlated positively with motor level and was highest in children receiving surgery within seven days of life.
- Shunt infections, multiple revisions, and extreme head circumference measurements were associated with poorer cognitive outcomes.
Impact:
- Findings suggest that early surgical intervention for hydrocephalus (within the first month) is critical for optimizing cognitive development in myelomeningocele patients.
- Reducing shunt-related complications, such as infections and reoperations, is essential for improving long-term intellectual outcomes.
- This research highlights the importance of a multi-faceted approach to managing myelomeningocele and associated hydrocephalus to enhance neurodevelopmental trajectories.
Abstract:
Myelomeningocele occurs in 0.4 for 1000 neonates and is associated with hydrocephalus in 85-90%, and reports on cognition are sparsely found in literature. Forty five children with treated hydrocephalus and myelomeningocele were studied in regard of IQ, and statistically correlated to functional motor level, age of the first shunt, number of revisions of shunt, infection of the shunt and circumference of the head. The medium age was of 7.5 years (3-15 years), 16 males and 29 females. Three (6.6%) had a IQ score > 110, 11 (24.4%) had a score between 100-110, 8 between 85-100 (17.7%), 16 (35.5%) between 85-100 (17.7%) and 7 (15.5%) between 50-70. IQ directly correlated with motor level, having better cognitive results the children with minor functional motor disabilities. Cognition was best in children operated until the seven day of life (t 0.0099), with progressive worse results in children operated after the first month of life, no significance was observed in children operated in the period 7 to 31 days (t 0.1013). Worse results were observed in the group of patients with infection of shunts (t 0.0146). Results were progressively worse with reoperations. The best results in relation of the circumference of the head were seen with children in the medium range (t 0.0115); intermediate results were seen in patients between the medium range and-1SD (t 0.00130) and medium range and +1SD. The worse results were seen in patients at the extremes of > 1SD (t 0.0269) and < ISD (t 0.0042). According to cognitive results the surgical treatment of hydrocephalus have to be done until the first month of life, avoiding reoperations and infections that have unfavorable impact in IQ.
