Case #2 A 50-year-old smoker with a family history of diabetes, hypertension, coronary artery disease and stroke, enters the urgent care clinic one evening complaining of a loss of sensation in their left lower limb. The physician conducts a complete neurological exam and notes that the patient does not perceive touch, pressure, or pain sensations on the anterior or posterior aspect of the left lower limb, while bilateral reflexes in the lower limbs appear normal. The patient can move their hip, knee, and ankle with full range of motion and does not report having had any back problems (e.g., slipped disks, degenerating disks, spinal stenosis, or muscle strains). The physician refers the patient to a neurologist who orders a functional MRI to assess brain activity in both superficial and deep brain structures.
