The diagnosis of amyotrophic lateral sclerosis can be challenging due to its heterogeneity in
clinical presentation and overlap with other neurological disorders. Diagnosis early in the …

Primary lateral sclerosis (PLS) has been traditionally viewed as a distinct upper motor
neuron condition (UMN) but is increasingly regarded as a sub-phenotype within the …

Background Primary lateral sclerosis is a progressive upper-motor-neuron disorder
associated with markedly longer survival than ALS. In contrast to ALS, the genetic …

Background Primary lateral sclerosis (PLS) is a low incidence motor neuron disease which
carries a markedly better prognosis than amyotrophic lateral sclerosis (ALS). Despite …

Motor neuron diseases encompass a divergent group of conditions with considerable
differences in clinical manifestations, survival, and genetic vulnerability. One of the key …
