#12I think the difference in outcomes is likely to be down to "continuous learning of new movement patterns and choreographies" vs "participants performed the same exercises repeatedly ... We avoided combined arm and leg movements in order to keep coordinative demands low". That said, I think dance is great.

#16"Regarding cognition, both groups improved in attention and spatial memory, but no significant group differences emerged." So, the dance group showed increase volume of brain matter. Is there a benefit to having the extra brain volume, even if it doesn't lead to improved cognition? Is it possible that increased volume just helped them become better dancers?
(IMO the headline-level conclusion of this study is unsurprising - dancing is far more cognitively demanding than gym exercise!)

#19The brain data claims to show that the dance vs. exercise groups showed different levels of improvement in various regions. However, the brain effects are tiny and are probably just random noise (I'm referring to those red spots, which are very small and almost certainly don't reflect proper correction for multiple hypotheses given that the authors effectively tested 1000s or 10000s of different areas). The authors' claims about BDNF are supported by a p-value of p = .046, and having main conclusions hinge on p-values of p > .01 usually means the conclusions are rubbish.
In general, my priors on "we can detect subtle changes in brain matter over a 6-week period" are also very low. Perhaps, a study with this sample size could show that activity of some kind influences the brain over such a short length, but I am extremely skeptical that this type of study could detect differences between dance vs. exercise effects.

#20Probably some styles of martial arts would (do imho) work well then. Disclaimer ; did not RTFA. Edit: +styles of
