What is a potential complication if multiple sclerosis is untreated for an extended period?

In the context of untreated multiple sclerosis (MS), potential complications can lead to significant worsening of the condition over time. The correct choice highlights that as the disease progresses without treatment, the symptoms can accelerate, leading to more severe neurological deficits.

Multiple sclerosis is characterized by the demyelination of nerve fibers in the central nervous system, which can result in a range of symptoms including muscle weakness, coordination issues, and sensory disturbances. When left untreated, the underlying inflammatory processes continue to damage the nerve cells and further complicate the condition, ultimately exacerbating the symptoms and potentially leading to increased disability.

Timely treatment is crucial in managing MS as it can help slow the progression of the disease, manage symptoms, and maintain quality of life. In contrast, the other options presented do not align with the well-documented trajectory of untreated MS. Complete recovery and prevention of plaques are not applicable, as MS is a chronic condition that usually does not allow for complete recovery, and plaques are a hallmark of the disease’s pathology. Increased resilience does not reflect the reality of disease progression; rather, untreated MS typically results in heightened vulnerability to further neurological compromise.
