Presentation
HSP can be classified as pure or uncomplicated if no additional findings are present (2). Age of onset of HSP can range from early childhood to late adulthood. [dnatesting.uchicago.edu]
HSP is classified according to the clinical phenotype as either pure or complex, the latter presenting with neurological and systemic impairments in addition to spastic paraparesis. [journals.lww.com]
RESULTS Six patients from two families presented with a slowly progressive, autosomal recessive, spastic tetraplegia. [jnnp.bmj.com]
The sister carrying the R294H variant had an ataxic gait and hand tremor at 3 years, which was not present in her sister. [epilepsygenetics.net]
Subtle childhood abnormalities may be present, but the main features develop in early adulthood. The disease is slowly progressive, and cerebellar and extrapyramidal signs are also found in patients with advanced disease. [uniprot.org]

Abstract Hereditary ataxia is a heterogeneous disorder characterized by progressive ataxia combined with/without peripheral neuropathy, extrapyramidal symptoms, pyramidal symptoms, seizure, and multiple systematic involvements. [e-jmd.org]

Treatment Treatment Options: No effective treatment is known for the neurological deficits but cataract surgery may be beneficial for visually significant cataracts. [disorders.eyes.arizona.edu]
However, HSPers report benefits from treatments as diverse as ankle / foot surgery where tendons are relocated, to fitness and specialised treatment from neurophysiotherapists for muscle strength and range of motion. [hspersunite.org.au]
Gene therapy may not work against all types of genetic disease, and it remains to be seen if any of the HSPs are candidates for this type of treatment. [medschool.lsuhsc.edu]
Prognosis
Determining the molecular basis of disease using genetic testing can be useful in predicting prognosis and disease course, and can aid in identification of at-risk family members. [dnatesting.uchicago.edu]
Abstract Although SPG11 is the most common complicated hereditary spastic paraplegia, our knowledge of the long-term prognosis and life expectancy is limited. [nature.com]
Prognosis [ edit ] Although HSP is a progressive condition, the prognosis for individuals with HSP varies greatly. It primarily affects the legs although there can be some upperbody involvement in some individuals. [en.wikipedia.org]
Prognosis: predicting symptoms and course of HSP As noted above, there is significant variation in HSP symptoms and their severity. This limits the certainty of making predictions. [rarediseases.org]
Etiology
Hereditary Spastic Paraplegia Etiology HSP is a highly genetically heterogeneous group of disorders (4). 70-80% of HSP is inherited in an autosomal dominant manner, and the majority of dominant HSP is classified as uncomplicated or pure HSP (2). [dnatesting.uchicago.edu]
