Which symptom is commonly associated with Multiple Sclerosis?

• A. Seizures
• B. Vision changes such as diplopia and nystagmus
• C. Aphasia
• D. Early memory loss

Answer: (B)

Multiple sclerosis affects the central nervous system in a way that frequently hits the pathways controlling vision and eye movements. In MS, demyelinating lesions can involve the optic nerves and the brain regions that coordinate gaze, leading to vision changes like double vision (diplopia) and involuntary eye movements (nystagmus). Optic neuritis, a common initial manifestation, often presents with vision loss and eye pain, underscoring how central demyelination can disrupt visual pathways. While seizures, aphasia, or memory changes can occur in MS, they are not as characteristic or as commonly observed as vision disturbances produced by optic and ocular motor pathway involvement.
