The Effects of Early-Life Iron Deficiency on Brain Energy Metabolism
Thomas W Bastian 2020https://doi.org/10.1177/2633105520935104
Iron deficiency (ID) is one of the most prevalent nutritional deficiencies in the world.
Iron deficiency in the late fetal and newborn period causes abnormal cognitive performance and emotional regulation, which can persist into adulthood despite iron repletion.
Potential mechanisms contributing to these impairments include deficits in brain energy metabolism, neurotransmission, and myelination. ...
We conclude that early-life ID impairs energy metabolism in a brain region- and age-dependent manner, with particularly strong evidence for hippocampal neurons.
Additional studies, focusing on other brain regions and cell types, are needed.

Among the tricarboxylic acid (TCA) cycle enzymes, aconitase and succinate dehydrogenase are iron-dependent.

Deficits in hippocampal energy metabolism also likely contribute to long-term hippocampal dysfunction through impaired neuronal structural maturation or persistently impaired energetic capacity
