Interactive computer-based cognitive training in patients with Alzheimer's disease.

The present paper presents data from ten patients suffering from mild to moderate Alzheimer's disease (AD), all of whom were trained to use an interactive computer-based program. Using photographs of the patient and his or her personal surroundings, an everyday task of relevance to the patient was simulated on a PC-touch screen, which the patient was trained to operate. After three weeks of training (three to four sessions a week), the patients needed less help in performing the programs, they became faster, and eight out of ten made fewer mistakes. The results were most pronounced in patients with a poor performance at the beginning, and there was no difference between early-onset (EO) and late-onset (LO) AD patients. Although the training was generally well received, there was no evidence of a general cognitive improvement, and it remains an open question whether the results achieved with PC training can be transferred to real-life situations.
