Hereditary Spastic Paraplegia (HSP) is a rare genetic disease that affects the nervous system. It is also known by several other names that describe the same condition. Some of the synonyms for HSP are Spastic Paraparesis, familial spastic paraplegia, and Strumpell-Lorrain disease. The symptoms of HSP include stiffness and weakness in the legs, poor balance, and difficulty walking. While there is currently no cure for HSP, treatment is available to manage the symptoms and improve mobility. In addition to physical therapy and medication, genetic counseling and testing can help individuals manage their risk of passing on the condition to future generations.
