Multiple sclerosis and amyotrophic lateral sclerosis: is there an association or a red flag? A case report and literature review.

Background: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system that causes damage to the myelin and axons and is caused by genetic or environmental factors. Amyotrophic lateral sclerosis (ALS) is characterized by rapidly progressive degeneration of the motor neurons resulting in the presence of upper and lower motor-neuron signs and symptoms.

Case Presentation: A 46-year-old female patient presented with symmetrical weakness of the lower limbs and numbness that developed over weeks.
