down sydrome
Down syndrome is a condition that typically comes from a faulty cell division before conception in either the egg or the sperm. The most frequent type is called Trisomy 21 because each cell has an extra chromosome 21. While mother of any age can have a child with Down syndrome, it is more likely to occur with older mothers. There is no cure for down sydrome since it happens during cell division and once the baby is born there is no way to reverse it. -

Hydrocephalus
Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. It surrounds the brain and spinal cord, and helps cushion the brain. To treat hydrocephalus there needs to be a shunt implanted either in the brain or in the spinal cord.
