Does everyone with Alpha-mannosidosis have hydrocephalus?
Hydrocephalus is something that can happen when the fluid in the brain and the spinal cord becomes blocked and causes increased pressure on the head. Hydrocephalus can occur in some people with Alpha-mannosidosis. This is something that can occur in people with Alpha-mannosidosis at any age, but this is not something that all people with Alpha-mannosidosis will have. There are scans, called CT scans, that can look at the fluid in the brain to see if a person with Alpha-mannosidosis has hydrocephalus.
