Presentation
Consistently formatted to present a clinical description of the disorder, followed by an in-depth analysis of the mutation and function of the mutated gene including cellular and animal models Emphasizes the use of DNA tests for each respective disorder [books.google.com]
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]
In severe form of Cervical Myelopathy causes muscle weakness in all 4 limbs with sensory disturbances.Pathological reflexes are also present. Hoffmann's sign and Babinski's sign also can be seen. [explainmedicine.com]
The risk of an individual inheriting the abnormal gene depends on the mode of transmission and whether the mutated gene is present on a sex chromosome or an autosome. [encyclopedia.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]
Neurologic

Involuntary Movements
Hereditary or genetic diseases featuring involuntary movements constitute a major aspect of the practice of neurology, functional neurosurgery, genetics, and many areas of basic and applied neuroscience research. [books.google.com]
Workup
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]
Treatment [ edit ] 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. [en.wikipedia.org]
Prognosis
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]
[…] inversely correlated with quality of life in a previous study. 31 As the majority of patients in our cohort who met the clinical criteria for HSP did not have a genetic diagnosis, this illustrates the need for studies of clinical parameters which influence prognosis [ng.neurology.org]

Pathophysiology
Pathophysiology [ edit ] The major feature of HSP is a length dependent axonal degeneration. [21] These include the crossed and uncrossed corticospinal tracts to the legs and fasciculus gracilis. [en.wikipedia.org]
