What is
Spina
Bifida?
Spina bifida
Spina bifida is a birth defect that involves
the incomplete development of the spinal
cord or its coverings. The term spina
bifida comes from Latin and literally
means "split" or "open" spine.
Spina bifida occurs at the end of the first
month of pregnancy when the two sides of
the embryo's spine fail to join together, leaving
an open area. In some cases, the spinal cord or
other membranes may push through this
opening in the back. The condition usually
is detected before a baby is born and treated
right away.
Types of Spina Bifida
Spina bifida occulta is the mildest form of
spina bifida (occulta means hidden). Most
children with this type of defect never have
any health problems, and the spinal cord is
often unaffected.
Spina bifida manifesta includes two types of spina bifida:
1. Meningocele involves the meninges, the membranes responsible for covering and protecting the brain and spinal cord. If the meninges push through the hole in the vertebrae (the small, ring-like bones that make up the spinal column), the sac is called a meningocele.
2. Myelomeningocele is the most severe form
of spina bifida. It occurs when the meninges
push through the hole in the back, and the
spinal cord also pushes though. Most babies
who are born with this type of spina bifida
also have hydrocephalus, an accumulation of
fluid in and around the brain.

Because of the abnormal development of and damage to the spinal cord, a child with myelomeningocele typically has some paralysis. The degree of paralysis largely depends on where the opening occurs in the spine. The higher the opening is on the back, the more severe the paralysis tends to be.
Children with spina bifida often have problems with bowel and bladder control, and some may have attention deficit hyperactivity disorder (ADHD) or other learning difficulties, such as hand-eye coordination problems.
Maternal folic acid deficiency has been
inked to spina bifida, and researchers
believe that many cases can be prevented
if women of childbearing age consume
folic acid every day.
It is important that folic acid consumption start before the onset of pregnancy to provide the best protection. Good sources of folic acid include eggs, orange juice, and dark green leafy vegetables. Many multivitamins contain the recommended dose of folic acid, too.
