Abstract Background: There are marked sex/gender differences in the prevalence and expression of neurodiversity. Yet, it is unclear how related mechanisms may affect symptoms. In present study we test whether previously reported greater male than female variability neuroanatomy to sex X-linked explain behavioral cognitive variation Method: The included a longitudinal twin (N=990 twins; 56% monozygotic, 7-14 yo). Results: Greater was most pronounced structure development cortical surface area. Twin modeling results support significant role X-chromosome neuroanatomical variation. addition, normative analysis, showed that deviations brain anatomy were associated neurodiverse behavior. Conclusions: These findings together highlight importance studying gender linked mental illness beyond mean group modeling.

Alzheimer disease (AD) is associated with multiple etiologies and pathological mechanisms, among which oxidative stress (OS) appears as a major determinant. Intriguingly, OS arises in various pathways regulating brain functions, it seems to link different hypotheses mechanisms of AD neuropathology high fidelity.

Abstract Most complex human traits differ by sex, but we have limited insight into the underlying mechanisms. Here, investigated influence of biological sex on protein expression and its genetic regulation in 1,277 brain proteomes. We found that 13.2% (1,354) proteins had sex-differentiated abundance 1.5% (150) sex-biased quantitative trait loci (sb-pQTLs). Among genes with expression, 67% concordance between transcript levels; however, effects were more evident at level. Considering 24 psychiatric, neurologic morphologic traits, an average 25% their putatively causal 12 sb-pQTLs. Furthermore, integrating sex-specific pQTLs sex-stratified genome-wide association studies six psychiatric conditions, uncovered another 23 contributing to these one not other.

Some mental health problems such as depression and anxiety are more common in females, while others autism attention deficit/hyperactivity (AD/H) males. However, the neurobiological origins of these sex differences poorly understood. Animal studies have shown substantial neuronal glial cell structure, human brain imaging only small differences, which largely reflect overall body size. Advanced diffusion MRI techniques can be used to examine intracellular, extracellular, free water signal contributions provide unique insights into microscopic cellular structure. extent exist metrics subcortical gray matter structures implicated psychiatric disorders is not known.
