ALS is best described as?

• A. The most common motor neuron disease, causing loss of voluntary muscle control.
• B. A rapidly reversible inflammatory condition of the peripheral nerves.
• C. A purely sensory neuropathy without motor involvement.
• D. A disease affecting only the cerebellum causing ataxia.

Answer: (A)

ALS stands for amyotrophic lateral sclerosis, a neurodegenerative disorder that targets motor neurons in the brain and spinal cord. When these neurons deteriorate, voluntary muscles lose their control, leading to progressive weakness, muscle wasting, fasciculations, and eventually trouble with speaking, swallowing, and breathing. Because both upper and lower motor neurons are affected, you may see signs like spasticity and brisk reflexes alongside muscle weakness and atrophy. This is different from inflammatory peripheral nerve conditions that can be rapidly reversible, from purely sensory neuropathies that spare motor function, and from cerebellar diseases that cause ataxia rather than loss of voluntary motor control.
