Neurologic
- Spastic Gait
If symptoms begin during the teenage years or later, then spastic gait disturbance usually progresses over many years. [ipfs.io]
Diagnosis of SPG is established by the following clinical features 1, 2 : Typical clinical symptoms of spastic gait impairment and neurologic findings of spastic weakness, hyperreflexia, typically associated with bilateral extensor plantar responses A [centogene.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
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
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 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]

Epidemiology Worldwide, the prevalence of all hereditary spastic paraplegias combined is estimated to be 2 to 6 in 100,000 people. [15] A Norwegian study of more than 2.5 million people published in March 2009 has found an HSP prevalence rate of 7.4/100,000 [ipfs.io]

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]
