Study: Alzheimer’s disease progression differences in men, women should be considered when screening

There’s new research supporting previous findings that there are sex-based differences in Alzheimer’s disease progression that should be considered when it comes to screening protocols.

Researchers at Georgia State University (which is just down the street from me) analyzed brain scans of 332 people at different Alzheimer’s stages. While males show earlier gray matter volume loss, their rate of loss tends to plateau, which may result in “earlier onset but slower progression of structural decline.” Conversely, females showed delayed brain atrophy when compared to males, but when the decline did begin, it was at a steeper rate.

The study explores 3 theories that may have an impact on why Alzheimer’s disease evolves differently in men and women: hormonal pathways, APOE-e4 mechanisms, and women’s higher cerebrovascular burden. As I’m a APOE-e4 carrier, it’s concerning that the body of research so far suggests that it contributes to “more severe outcomes in women.” Obviously there’s nothing I can do about genetics, but it’s important to be aware of such factors.

Research will continue in this area to determine if sex-specific screening may support “earlier, more precise interventions.” This is critical because current treatments typically work best in the earlier stages of the disease.
