Vitamin B6 (Pyridoxine) The diagnosis of pyridoxine dependency should be suspected in every infant with convulsions in the first eighteen months of life. Certain clinical features may be indicative, including: Seizures of unknown origin in a previously normal infant without an abnormal gestational or perinatal history. A history of severe convulsive disorders, in both the family and the individual. The occurrence of long-lasting focal or unilateral seizures, often with partial preservation of consciousness. Irritability, restlessness, crying and vomiting preceding the actual seizure.* If large amounts of B6 alone are given, the need for other B vitamins, particularly vitamin B2 and pantothenic acid, is so increased that harm can be done unless they too are supplied. *Morello, Gaetano.
