Relationship between Body Mass index and microstructural indices in the fornix and parahippocampal cingulum as well with whole brain and hippocampal volume for the normal and overweight individuals (BMI 20–30) (n = 34).

Abbreviations: AD: axial diffusivity; BMI: Body Mass Index; BPF: Brain Parenchymal Fraction; FA: Fractional Anisotropy; HCV: Hippocampal volume; MD: Mean diffusivity; PHC: parahippocampal cingulum (collapsed across hemispheres); RD: radial diffusivity. Pearson correlation coefficients significant at Bonferroni corrected level of p<0.005 are highlighted in bold and correlations with significance below the uncorrected 5% level are highlighted in italics.
**p≤0.01;
***p≤0.001.
