G11.4: Hereditary spastic paraplegia

You have a condition that means you cannot move your legs properly.

To be able to move muscles properly, they need to be controlled by the nervous system. The nervous system includes the brain and the spinal cord, for example. The spinal cord is located in the spinal column. The spinal cord is made up of nerve fibers. The brain uses the nerve fibers to exchange information with the organs, skin and muscles.

With this condition, certain nerve fibers in the brain and spinal cord suffer increasing damage. In particular, nerve fibers that control leg muscles are affected. This makes leg movements more difficult. It makes the leg muscles cramp up. You may also be unable to balance properly. You may have problems when passing water. There may be other symptoms, too.

The condition is usually inherited. Other family members may then be affected, too.
