What happens in Myelomeningocele?
Meninges and spinal nerves come through the open part of the spine.
What is a common treatment for Myelomeningocele?
Urgent surgery.
What can be affected below the nerve damage in Myelomeningocele?
Development of muscles and limbs.

They grow up to live independent lives.
What percentage of individuals with Myelomeningocele and Meningocele develop hydrocephalus?
70-90%.
What is hydrocephalus?
Excessive accumulation of cerebrospinal fluid (CSF) in and around the brain.
What can happen if cerebrospinal fluid cannot drain independently?
It collects in and around the brain.
What are some possible effects of high fluid pressures on the brain?
- Impaired vision
- Hearing loss
- Mobility issues
- Coordination problems
- Seizures
- Headaches
- Hormonal imbalance
- Learning disabilities
What is the common treatment for hydrocephalus?
Surgically implanting a shunt.
Where does the shunt drain excess cerebrospinal fluid?
From the brain to either the stomach or heart.
What is hydrocephalus?
A condition characterized by an accumulation of cerebrospinal fluid (CSF) in the brain’s ventricles.

Signs include:
* Nausea
* Projectile vomiting
* Unexplained pupil dilation
* Seizures
* Headaches
* Drowsiness
What is the cause of spina bifida?
The cause is largely unknown but believed to involve genetic and environmental factors.
What role does folic acid play in preventing spina bifida?
A deficiency in folic acid in a mother’s diet, combined with genetic factors, appears to increase the risk of spina bifida.
