A 28-year-old woman visits the neurology clinic with a history of recurrent neurological symptoms. She reports experiencing episodes of numbness and tingling in her legs, difficulty walking, and blurred vision that comes and goes. The symptoms have been occurring over the past two years, with periods of remission in between. The patient mentions that her symptoms worsen when she’s stressed or fatigued. On examination, there is evidence of weakness and reduced coordination in her legs, and she displays involuntary eye movements (nystagmus). An MRI of the brain reveals multiple areas of demyelination in different regions. The neurologist considers a diagnosis of Multiple Sclerosis.
