neurological deficits is not due to folic acid deficiency but due to lack of B12.

Vit B12 (Cyanocobalmin)--causes Megaloblastic anemia & Neurological deficits, due to the accumulation of methylmalonic acid in the myelin-sheets..
Folic acid def causes only Megaloblastic anemia without any neurologic deficits. So, giving folic acid will correct the anemia, but will not treat the neurologic symptoms. |
