The biomarker myokine Cathepsin B (CTSB) increased after a 26-week aerobic exercise training program. CTSB may be useful as a marker for cognitive changes  in a population at risk for dementia.

The largest study of its kind has uncovered new insights into how genes are regulated in dementia, including discovering 84 new genes linked to the disease.
