Which of the following is a common nervous system disease that can lead to mobility issues?

Multiple sclerosis is indeed a common nervous system disease that can lead to mobility issues. This condition affects the central nervous system by disrupting the communication between the brain and the body. It can cause a range of symptoms, including muscle weakness, coordination problems, and difficulty with balance, all of which directly impact a person's ability to move and perform everyday activities. As the disease progresses, these mobility challenges can become more pronounced, significantly affecting an individual's quality of life and independence.

In contrast, while epilepsy involves the nervous system, it primarily manifests through seizures rather than consistent mobility issues. A stroke, or cerebrovascular accident (CVA), certainly can affect mobility, but it is more often associated with sudden onset neurological damage rather than being classified as a chronic disease affecting the nervous system through ongoing degeneration. Congestive heart failure is a cardiovascular issue rather than a nervous system disease and affects mobility typically through accompanying fatigue or weakness rather than the direct neurological effects seen in multiple sclerosis.
