Abstract: In the last years, many clinical studies highlighted sex-specific differences in the pathophysiology of Alzheimer’s disease (AD). The recent paper published in the Journal of Alzheimer’s Disease shows the influence of sex on amyloid-β plaque deposition, behavior, and dopaminergic signaling in the 5xFAD mouse model of AD, with worse alterations in female mice. This commentary focuses on the importance of recognizing sex as a key variable to consider for a more precise clinical practice, with the challenge to develop sex-specific therapeutic interventions in neurodegenerative diseases such as AD.
