Our findings confirm that this is indeed not an uncommon presentation of this disorder and we suggest that SPG7 gene analysis should be included in the diagnostic workup of autosomal recessive PEO, especially if spasticity is present. [journals.plos.org]

Treatment No specific treatment is known that would prevent, slow, or reverse HSP Available therapies mainly consist of symptomatic medical management and promoting physical and emotional well-being 26. Gen. Spas ticity Oral Agents Foc. [slideshare.net]

Treatment There is no curable or preventive treatment for HSP. Symptomatic treatment for muscle spasm and spasticity includes oral medications like baclofen, tizanidine, and benzodiazepines like valium. [encyclopedia.com]

Standard Therapies Treatment: management of symptoms Despite encouraging progress in many research laboratories (see reference 7 for example), treatment for HSP is presently limited to reducing symptoms of muscle weakness, spasticity, and urinary urgency [rarediseases.org]

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]

Prognosis This varies widely, but most often HSP is compatible with a normal life expectancy. The rate of progression varies considerably and is influenced by the mode of inheritance. [encyclopedia.com]

Identification of the specific mutation concerned is essential to establishing a prognosis and providing satisfactory treatment and proper genetic counselling. [elsevier.es]
