The present invention relates to a method for screening stem cells effective in the treatment of brain-nervous system diseases and, more specifically, to an evaluation platform which mimics the states of brain-nervous system diseases by using a three-dimensional brain organoid, and treats the brain organoid with stem cells so as to compare and analyze treatment effects, thereby being capable of predicting the treatment effect of the stem cells in advance, and selecting only the stem cells effective in treatment. Compared to conventional methods which have blindly applied stem cell treatment without verification, the provision of the method for screening stem cells, according the present invention, is expected to innovatively improve the treatment effects and increase the uniformity of treatment results, and ultimately, to suggest an alternative which enables stem cell treatment to be utilized universally.
