Re: Brain Age/Dr Kawashima's Brain Training

The Nintendo DS is a handheld console, so there are no NTSC or PAL versions of DS games as those are television standards.

NOTE: Since this game was first released in Japan, it is likely optimised for NTSC, as opposed to PAL. As such, I'd recommended downloading the US version, if you can't decide which region to download.
Have fun!!!
