How iron-deficiency anemia in later childhood affects the brain and thinking

Neurocognitive Effects of Late-Childhood Iron Deficiency Anemia

['FUNDING_R01'] · WASHINGTON UNIVERSITY · NIH-11169048

This project looks at girls and young women aged 12–21 with iron-deficiency anemia to see how it changes brain metabolism, blood flow, and thinking using cognitive tests and MRI scans.

What this research studies

If you are a girl or young woman aged 12–21 with iron-deficiency anemia, researchers will invite you to do memory and attention tests and have MRI scans that measure brain blood flow, oxygen use, and brain connections at the time your anemia is diagnosed and at follow-up. The team plans to enroll about 88 participants and will link the MRI measures to performance on cognitive tests to understand how anemia affects the brain. They will look for signs that some brain changes improve with treatment while others may last longer. The goal is to map short- and long-term effects of late-childhood anemia on brain structure, function, and thinking.

Who could benefit from this research

Good fit: Ideal participants are females aged 12–21 who have been diagnosed with iron-deficiency anemia.

Not a fit: People without iron-deficiency anemia, males, or those outside the 12–21 age range are unlikely to be eligible or directly benefit from this specific project.

Why it matters

Potential benefit: If successful, the work could show which brain effects of late-childhood iron-deficiency anemia are reversible and guide better timing for screening and treatment.

How similar studies have performed: Previous studies have linked early- and late-childhood iron deficiency to poorer cognitive performance, but applying MRI measures of cerebral metabolism and connectivity in this age group is relatively new.
