What vitamin deficiency is associated with hypoxic-ischemic encephalopathy (HIE)?

Hypoxic-ischemic encephalopathy (HIE) is a condition resulting from a lack of oxygen and blood flow to the brain, often seen in newborns. Vitamin B6, also known as pyridoxine, plays a crucial role in brain development and function, and its deficiency can contribute to neurological issues.

In the context of HIE, Vitamin B6 is significant because it is involved in the synthesis of neurotransmitters, including gamma-aminobutyric acid (GABA) and serotonin, which are essential for proper neuronal signaling and development. A deficiency in this vitamin may exacerbate the damage done during hypoxic-ischemic events by impairing neurotransmitter activity and neuroprotective mechanisms. Therefore, recognizing the link between Vitamin B6 deficiency and HIE is crucial in understanding the broader implications for neonatal brain health and development.

While other vitamins are important for various metabolic functions, their direct association with HIE is not as substantiated as that of Vitamin B6. Vitamin A is primarily involved in vision and immune function, Vitamin D in bone health and immune response, and Vitamin C in antioxidant defense and collagen synthesis, but none have a direct and clear link to the mechanisms involved in hypoxic-ischemic injury as does
