Normalized temporalis muscle volume

1. Normalized temporalis muscle volume protects against dementia in humans (HR 0.3 (95% CI 0.1-0.8)).

   “Males, but not females, with higher normalized temporalis muscle volume were protected against conversion to early dementia (HR(95%CI):0.3(0.1‐0.8))”

1. Normalized temporalis muscle volume is associated with precuneus volume in humans.

   “Correlation analyses showed a direct relationship between the volume of the temporalis muscles and volume of the precuneus and entorhinal cortices”
