  Cerebellar signs were present in 4 patients (family I) and consisted of a dysarthric cerebellar speech, dysmetria, and abnormal rapid alternating movements in the upper extremities. [ajnr.org]

  A trace of terminal dysmetria may also be found in the upper limbs, but more florid cerebellar signs are not seen. [jnnp.bmj.com]

  There were subtle cerebellar signs in the upper limbs and mild cerebellar dysarthria. Ophthalmological examination showed normal retinal and macular findings, but visual acuity was 0.3–0.5. [journals.plos.org]

While this adds considerable challenges in the diagnostic workup, certain specific complicating features may guide the differential diagnosis between the different HSPs. [scielo.br]

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]

SPG2 - these patients tend to have a normal lifespan. [ 6 ] There may appear to be periods of stability but the prognosis is for gradual deterioration. [patient.info]

Prognosis Most patients become wheelchair-bound by the 5th decade of life. Death generally occurs during the sixth decade but survival into the seventies has been reported. [orpha.net]

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]

Disorders, the prognosis of which differs significantly from HSP, such as multiple sclerosis and familial motor neuron disease should also be excluded. The necessity for investigations will vary depending on the individual clinical picture. [jnnp.bmj.com]

Accordingly, plasma oxysterols are biomarkers that should be included in the screening of any spastic paraplegia of unknown etiology. [oxfordmedicine.com]

Etiology ARSACS is caused by autosomal recessive mutations in the SACS gene (13q11), which encodes a large protein of unknown function named sacsin. [orpha.net]

Diagnosis is also warranted to prevent patients from been submitted to unnecessary diagnostic tests. Patients with pure HSP mostly have a normal life-spam. [scielo.br]
