Which of the following is NOT a common symptom of MS?

The correct choice indicates that hyperactivity is not a common symptom of Multiple Sclerosis (MS). In MS, symptoms typically arise due to the demyelination of nerves in the central nervous system, which can lead to a variety of issues including cognitive dysfunction, bladder and bowel dysfunction, and ambulation problems.

Cognitive dysfunction in individuals with MS can manifest as difficulties with memory, attention, and problem-solving, highlighting the impact of the disease on cognitive function. Bladder and bowel dysfunction are also frequently seen, as MS can disrupt the signals between the brain and these bodily functions. Furthermore, ambulation problems are common, with many patients experiencing difficulty walking due to weakness, coordination issues, or spasticity leading to challenges with balance and mobility.

Hyperactivity, on the other hand, does not align with the typical symptomatology of MS. Instead, patients often experience fatigue and reduced energy levels, making hyperactivity an unlikely feature. Recognizing the distinct clinical manifestations of MS is crucial for proper diagnosis and management.
