The same study found that other areas in the DMN are turned on more than in controls.

Intuitively, the idea that depression could change activity in the DMN makes sense, since depression is linked to problems with concentration and attention, as well as with the tendency for rumination.

It seems like almost any activitythat forces the problem-solving areas of the brain to engage and DMN to quiet down (diving into work you love, or maybe even attempting a Sudoku) might be able to help keep the brain healthy for longer.
