Abstract

Vitamin B12 deficiency causes a variety of symptoms in the hematologic, gastrointestinal tract, and neurologic deficit. We report a rare case of progressive gait disturbance, bradykinesia and dysarthria which was that vitamin B12 deficiency was diagnosed as the cause, and symptoms improved after intramuscular cobalamin treatment. Vitamin B12, homocysteine, and methylmalonic acid tests are recommended for patients with progressive gait disturbance, even in the absence of obvious anemia symptoms.
