Study Notes

Sex effects on drug metabolism contribute to differences in treatment outcomes for Parkinson's and schizophrenia
Specific sex-genotype interactions, such as APOE genotype x sex, affect treatment response for Alzheimer's disease

Evolutionary theory, genetic differences, and environmental factors may produce sex differences in human brain organization
Sex differences in the prevalence and presentation of brain-based diseases, such as Alzheimer's and Parkinson's, provide indirect evidence for sex differences in brain organization

Individual differences in sex chromosome complement and gonadal sex steroids may directly impact brain organization
Presence of the SRY gene on the Y chromosome leads to differentiation of testes, whereas absence of this gene leads to differentiation of ovaries in placental mammals
Gonadal divergence leads to distinct concentration profiles of sex steroids (e.g., estrogens, androgens) throughout development

Highly reproducible sex differences in regional brain anatomy exist above and beyond sex differences in overall brain size
These differences are characterized by small-to-moderate effect sizes and show largely overlapping distributions
The microstructural basis, causal factors, and behavioral implications of these differences are not yet understood

There is a pressing need to better understand the developmental unfolding of sex differences in human brain anatomy over time
Large longitudinal neuroimaging datasets and recent advances in modeling dynamic sex differences will facilitate this research
