Y1 - 1 N1 - T2 - Practice of Neural Science: A Case-Based Approach AB - Following a year of erectile dysfunction and nocturnal urinary frequency, a 57-year-old man experiences blurred vision during exercise. Over the next several months, his symptoms increase; when he stands for more than a few minutes or walks a few hundred yards, he experiences constriction of his visual fields and loss of color perception followed by lightheadedness and diffuse weakness. If he does not then sit down, he loses consciousness. Neither pallor nor sweating precedes syncope. Over the next year, he develops slowly progressive facial immobility and bradykinesia but not tremor, ataxia, or dysarthria.
