Presentation
Hyperreflexia is another key feature of PLS as seen in patients presenting with the Babinski's sign. [en.wikipedia.org]
Mimics can be grouped into those presenting with LMN- or UMN-only signs and those with mixed signs. LMN presentations represent the greatest diagnostic challenge. [pn.bmj.com]
Results: All affected individuals presented in the second year of life with progressive upper motor neuron dysfunction, affecting both bulbar and extremity muscles. [neurology.org]
Clinical presentation ALS may present initially with signs of only upper or lower motor neuron involvement. [emedicine.medscape.com]
We suggest that the ALS2 gene should be screened for mutations in patients who present with a similar phenotype. Read more: http://www.neurology.org/content/82/12/1065.long [foundationdystoniaresearch.org]

Lower motor neuron loss causes initially increased electrical excitability leading to fasciculations, and later muscle weakness and atrophy; upper motor neuron involvement causes spasticity, clonus, hyperactive tendon reflexes, and Babinski signs. [neuropathology-web.org]
All deep tendon reflexes were exaggerated with bilateral ankle clonus and Babinski sign. There was no sensory or cerebellar dysfunction. Routine hematological and biochemical investigations including chest X-ray were normal. [neurologyindia.com]

Prognosis
Prognosis - Juvenile primary lateral sclerosis he \'prognosis\' of Juvenile primary lateral sclerosis usually refers to the likely outcome of Juvenile primary lateral sclerosis. [checkorphan.org]
Prognosis The prognosis is guarded, with the clinical signs having a major impact on quality of life. The documents contained in this web site are presented for information purposes only. [orpha.net]
Prognosis A distinctive clinical feature of PLS is that it has a very slow progression, leading it to be considered to have a more benign prognosis in comparison to ALS [3]. [physio-pedia.com]

(See Prognosis and Treatment.) The slow rate of progression of PLS provides most patients and families with time to adapt to the changes and identify resources for support. [emedicine.medscape.com]
Etiology
[…] maintain a repository of clinically characterized patients with primary lateral sclerosis for future research protocols, to characterize the natural history of neurodegenerative disorders with corticospinal neuron degeneration, to investigate proposed etiologies [clinicaltrials.gov]
Etiology Mutations in the ALS2 gene (2q33-q35) encoding alsin, a protein that is abundant in motor neurons, and less commonly mutations in the ERLIN2 gene (8p11.2) have been reported. [orpha.net]
OBJECTIVE: To determine the genetic etiology in 2 consanguineous families who presented a novel phenotype of autosomal recessive juvenile amyotrophic lateral sclerosis associated with generalized dystonia. [foundationdystoniaresearch.org]
Etiology and Patogenesis [ ✎ edit | edit source ] There is one special form of PLS, which occurs in childhood, called juvenile primary lateral sclerosis. Nowadays, we know that there is a gene transmited from parents to their children, called ALS2. [wikilectures.eu]
Etiology and Pathophysiology PLS is usually sporadic with no known cause; potential role of TAR DNA–binding protein 43 (TDP-43) ( 1 ) Genetics Juvenile PLS and juvenile ALS has been correlated with a mutation in the ALS2 gene on chromosome 2. [unboundmedicine.com]
