Amyotrophic lateral sclerosis (#ALS) is an adult-onset neurodegenerative disorder characterized by progressive muscle weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord.

Diagnosis relies on clinical criteria with mixed upper and lower motor neuron features, and is often supported by electromyography and genetic testing, which may direct treatment.
