This is the second Seminar Paper I wrote for University and it is concerning the effects games can have on dementia patients. First explaining what dementia is in detail and what can be useful therapies for it, I'll move on to looking at board games that are used for helping dementia patients. Afterwards I'll elaborate on some digital games that show positive effects in the therapy of dementia patients. I conclude with a small guide of what Game Designers should keep in mind when creating games that should have therapeutical effects on people suffering from dementia.
