Abstract:
Amyotrophic lateral sclerosis is a progressive neurodegenerative disorder involving primarily motor neurons in the cerebral cortex,brainstem and spinal cord.The clinical diagnosis of ALS may be categorized into four levels of certainty according to clinical and electrophysiological examination,depending on the presence of upper and lower motor neuron signs together in the same topographical anatomic region in either the brainstem(bulbar cranial motor neurons),or cerival,or thoracic,or lumbosacral spinal cord(anterior horn motor neurons).Electromyography is of great importance in the diagnosis of ALS.Neruoimaging studies and clinical laboratory studies are helpful to exclude other disorders.
