A 35-year-old patient presents to the neurology clinic with a history of unusual and seemingly unrelated neurological symptoms that have occurred in distinct episodes over the past 18 months. Approximately a year and a half ago, they experienced a period of blurry vision in their right eye that resolved on its own after a few weeks. Several months later, they developed numbness and tingling sensations in their left hand and foot, which also improved over time but did not fully disappear. Most recently, they report increasing fatigue, difficulty walking steadily, and new onset weakness in their right leg. Physical examination confirms mild weakness in the right lower extremity, decreased proprioception in the feet, and slight gait unsteadiness. The patient notes that while some symptoms resolve, others appear, and the overall pattern feels inconsistent but worsening over time. Based on the patient’s history of fluctuating neurological deficits affecting multiple areas and the types of symptoms reported, which condition and its primary affected nervous system structures is most likely causing these issues?
