Other early signs of cerebellarataxia include dysarthria and nystagmus. The spasticity is progressive and eventually dominates the clinical picture. The pyramidal syndrome is characterised by brisk patellar tendon reflexes and the Babinski sign.[orpha.net]

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