Ms. K is а 22 yeаr оld white femаle. She came tо Neurоlogy Clinic for evaluation of her long-term neurologic complaints. The patient relates that for many years she had noticed some significant changes in neurologic functions, particularly heat intolerance precipitating a stumbling gait and a tendency to fall. Her visual acuity also seemed to change periodically during several years. Two months ago the patient was working very hard and was under a lot of stress. At that time, she could not hold objects in her hands, had significant tremors and severe exhaustion. She also had several bad falls. Since that time she had noticed arthralgia on the right and subsequently on the left side of her body. Then, the patient abruptly developed a right hemisensory deficit after several days of work. She remains weak and numb on the right side; she has impaired urinary bladder function which requires multiple voids in the mornings, and nocturia times 3. She became incontinent and now has to wear a pad during the day. She also has persistent balance problems with some sensation of spinning, and she is extremely fatigued. Motor examination reveals relatively lower strength in the upper extremities throughout. However, rapid alternating movements are decreased in both upper extremities . Mild paraparesis is noted in both legs without severe spasticity. Sensory exam reveals numbness on the right upper and lower limb. The patient has mild vibratory sense loss in the distal lower extremities. She also complained of pain in right upper abdominal area. What is the pathophysiology of her condition?
