Author Information
Author(s): Omori Naoki, Ishida Manabu, Takamura Masahiro, Abe Satoshi, Nagai Atsushi
Primary Institution: Shimane University
Hypothesis
This study aimed to analyze the association between anemia and brain volume using magnetic resonance imaging data from brain health checkups.
Conclusion
The study suggests that anemia may be associated with smaller brain volumes, particularly in the limbic system, with notable differences between sexes.
Supporting Evidence
- Anemia is a risk factor for dementia development.
- Lower blood hemoglobin levels were associated with smaller total intracranial and gray matter volume.
- Male participants with anemia had smaller bilateral frontal lobe volumes.
- Female participants with anemia had smaller limbic system volumes.
Takeaway
Anemia might make parts of your brain smaller, especially in women, which could affect how well you think.
Methodology
Participants underwent brain health checkups, blood samples were taken to measure hemoglobin, and MRI scans were analyzed using voxel-based morphometry.
Potential Biases
Potential confounding factors such as nutritional status and alcohol use were not measured.
Limitations
The study is cross-sectional, which limits causal inferences, and the sample may not represent the general population.
Participant Demographics
Participants were mainly middle-aged or older adults living in the local community, with 45.87% being women.
