| Spastic paraplegia type 5A : Spastic paraplegia type 5A is one of a group of genetic disorders known as hereditary spastic paraplegias. These disorders are characterized by muscle stiffness (spasticity) and severe weakness in the lower limbs (paraplegia). Hereditary spastic paraplegias are often divided into two types: pure and complex. The pure types involve spasticity and weakness only in the lower limbs, while the complex types involve additional problems with other areas of the body; additional features can include changes in vision, changes in intellectual functioning, brain abnormalities, and disturbances in nerve function (neuropathy). Spastic paraplegia type 5A is usually a pure hereditary spastic paraplegia, although complex type features have been reported in some individuals, usually in those who have had the condition for many years. In addition to spasticity and weakness, people with spastic paraplegia type 5A can lose the ability to sense the position of their limbs or detect vibrations with their lower limbs. They may also have muscle wasting (amyotrophy), reduced bladder control, or high arches of the feet (pes cavus). The signs and symptoms of spastic paraplegia type 5A usually appear in adolescence but can begin at any time between infancy and mid-adulthood. The condition slowly worsens over time, often leading affected individuals to require walking support or wheelchair assistance. | |
