Latest brain imaging study: changes in female brain during menopause are distinct from those during pregnancy and adolescence

A recent brain imaging study published in the international academic journal Nature Communications found that changes in the female brain during menopause are significantly different from those during pregnancy and adolescence. Puberty and pregnancy are associated with reduced cortical gray matter volume, whereas gray matter volume remains relatively stable during the menopausal transition.
