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]

• Difficulty Walking

  The onset of symptoms varies greatly; however, abnormalities in muscle tone and difficulty walking usually become noticeable in adolescence. Many features of spastic paraplegia type 11 are progressive. [ghr.nlm.nih.gov]

  Balance difficulty, often worse when walking in the dark or on uneven surfaces is not uncommon in individuals with HSP. Tightness in the legs and leg muscle spasm (often at night) are not uncommon. [rarediseases.org]

  Progressive difficulty walking is the main problem and occurs due to taut and weak muscles. This manifests initially as stumbling, stubbing the toe, catching of the feet on uneven surfaces and sidewalks, clumsy gait, or difficulty with balance. [encyclopedia.com]

  Most patients present with difficulty walking or gait disturbance, noticed either by themselves or a relative. In those with childhood onset, a delay in walking is not uncommon. [jnnp.bmj.com]

  Most people experience a decline in intellectual ability and an increase in muscle weakness and nerve abnormalities over time. As the condition progresses, some people require wheelchair assistance. [ghr.nlm.nih.gov]

  Over 70 genotypes have been described. Over 50 genetic loci have been linked to this condition. [10] Ten genes have been identified with autosomal dominant inheritance. One of these SPG4 accounts for ~50% of all cases. [ipfs.io]

• Hyperreflexia

  People with this form of spastic paraplegia can also experience numbness, tingling, or pain in the arms and legs (sensory neuropathy); disturbance in the nerves used for muscle movement (motor neuropathy); intellectual disability; exaggerated reflexes (hyperreflexia [ghr.nlm.nih.gov]

  Upper limb involvement is relatively uncommon and usually consists of mild hyperreflexia, which may be present early in the disease. A trace of terminal dysmetria may also be found in the upper limbs, but more florid cerebellar signs are not seen. [jnnp.bmj.com]

  Diagnosis HSP is diagnosed by the following: 1) typical symptoms (lower extremity spastic weakness that may be non-worsening (early childhood onset) or slowly progressive over many years; 2) findings on neurologic examination (lower extremity hyperreflexia [rarediseases.org]

  All of them started with symptoms consisting of gait difficulties and weakness in the lower extremities, and their neurologic examination showed an upper motor neuron syndrome predominantly in the lower extremities with weakness, spasticity and hyperreflexia [ajnr.org]

  His deep tendon reflexes were normal in the upper limbs but enhanced in the lower limbs, and Babinski sign was positive bilaterally. Extrapyramidal signs were not noted. His gait was wide-based, staggering and spastic. [nature.com]

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 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 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. [ipfs.io]

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]

Prognosis Edit Although HSP is a progressive condition and usually starts in the legs and spreads to other muscles, ultimately leading to confinement to bed, the prognosis for individuals with HSP varies greatly. [psychology.wikia.com]
