That's a very interesting paper @pattismith . Thanks for sharing. Even though the hippocampus is more vulnerable to oxidative stress due to its higher metabolic rate, it's also a prominent site of neurogenesis, unlike in the cortical brain. So, to oversimplify it a little, the hippocampus may be easily damaged, but it is also easily repaired.
The hippocampus is particularly vulnerable to brain iron deficiency either (for the same reasons)

Abstract
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.

Here, we comprehensively review the existing data that demonstrate diminished brain energetic capacity as a mechanistic driver of impaired neurobehavioral development due to early-life (fetal-neonatal) ID.

We further discuss a novel hypothesis that permanent metabolic reprogramming, which occurs during the period of ID, leads to chronically impaired neuronal energetics and mitochondrial capacity in adulthood, thus limiting adult neuroplasticity and neurobehavioral function.

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.
