Gamasutra reports that a hospital in Japan has begun renting out DSes and suggesting the title Brain Training to older patients, in an effort to stave off dementia. From the article: "Sixty-seven year old retiree Isamu Shishido is quoted as saying, 'I don't want to end up some crazy old man. I want to play a little everyday before going to bed.' Neurosurgeon Dr Takeshi Kihara comments that, 'The game won't cure dementia. But it's a good form of stimulation, especially for old people living alone.'"
