» Voxel Based Morphometry (VBM)
We use voxel based morphometry (VBM) on clinical and population based samples. We are highly interested in adding factors known to have an impact on brain volume in our statistical analyses. Population based data obtained at the same MRI are a huge challenge for that approach. The main parameters included as confounds are demographic (age, sex see: Lotze et al., 2019), social (education time, income, social interaction), and health behaviour (smocking, alcohol, sports in leisure time, body mass index). Other parameters are often applied for exclusion of participants (radiologic pathology, chronic diseases, psychiatric or neurologic diseases) or for additional information of possible other impact on the brain (e.g., medication). Additional quality parameters and the total brain volume are used as confounders for the statistical analysis too. Many parameters interact in the same direction on the same areas of the brain such as chronic pain (e.g., Fritz et al., 2015; Domin et al., 2021), smoking habits (Fritz et al., 2014), sleep deficit, or chronic stress. Some of these findings have been obtained in large samples of different research groups and seem to be quite robust. The absence of these factors increase quality of life (Hahm et al., 2019) and interacts with income (Lotze et al., 2020). In addition, these participants spent more time with leisure sports (Eyme et al., 2018) and therefore show opposite effects on the brains GMV (increase in medial prefrontal GMV with higher quality of life; increase in hippocampus/amygdala GMV with higher income and less stress).An interesting topic is the interaction of these factors with brain maturation which is investigated in cohorts including younger participants. In contrast, protective effects for age related decline in GMV has been investigated for the effect of education (Lotze et al., 2020), and sports (Eyme et al., 2018). A big challenge are longitudinal assessments which are however challenging to evaluate and need more elaborate statistical processes.
