Progress in clinical diagnosis of amyotrophic lateral sclerosis
Abstract
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, mainly involving the pyramidal tract, brain stem and spinal cord anterior horn cells, manifests as progressive muscle atrophy, weakness and cramps, as well as cognitive impairment, and may overlap with frontotemporal dementia. ALS is familial in 5% of cases, whose clinical manifestations are similar to sporadic. The diagnosis is made mainly based on clinical manifestations, using internationally recognized consensus standard, after rule out conditions that can mimic ALS. Genetic testing provides a new way to accelerate the diagnostic process for early intervention. Part of the gene mutations are associated with specific phenotypes. According to this, prognosis assessment and genetic counseling are able to carry out. DOI:10.3969/j.issn.1672⁃6731.2012.03.004
