Some forms of hormone replacement therapy (HRT) can slightly shrink the brains of post-menopausal women, a US study has suggested.

The findings may help explain previous work linking HRT to an increased risk of memory loss and dementia.

A team led by researchers at Wake Forest University carried out brain scans on 1,400 women aged 71 to 89 who took part in an earlier HRT trial.
