One should really not draw conclusions based on this. * It's a (small) group of 63-80 year olds. * There's no evidence for increased neuro-plasticity. How could there be? There's only an dubious effect on BDNF plasma and "BDNF may be a possible mediating factor of adult neuroplasticity". * The groups start out with a difference, but by misapplying statistics, they conclude there's no difference.
