Eight patients suffering from senile dementia were treated utilizing a series of computerized visual recognition training tasks. The training tasks included one each dynamic and static procedures. The dynamic task was to recognize and pursue a smoothly moving target among several obstacle characters, and the static task was to recognize a specific alphabetic letter among many letters. 0ne training set took about 25-30 minutes, and three sets were done per week for four weeks. After the training period was over, the response time required to recognize the moving target (dynamic task)and a specific letter (static task) was shortened significantly. The right answer rate increased as well. Moreover, the subjects' performance on cognition testing (mini-mental state examination) improved after the four-week rehabilitation training. These results suggest that patients with senile dementia may benefit from this kind of visual recognition training, and the probable mechanism may lie in the reactivity of the brain under cognitive visual stimulation.
