Hereditary Spastic Paraplegia (HSP) is a group of clinically and genetically heterogeneous disorders characterized by lower extremity spasticity and weakness.

HSP is classified as uncomplicated, or pure, when only spinal involvement occurs, and is classified as complicated when accompanied by other system involvement or other neurologic findings such as ataxia, seizures, intellectual disability, dementia, amyotrophy, extrapyramidal disturbance, or peripheral neuropathy.

HSP can be inherited in an autosomal dominant, autosomal recessive, x-linked recessive or maternally inherited (mitochondrial) manner.

The prevalence of all hereditary spastic paraplegias is estimated to be 2 to 6 in 100,000 people worldwide.
