Cognitive Training in Early to Moderate Stages Alzheimer's Disease Patients: Contribution of Digital Remote Training
Cerebral functioning changes with age in order to respond to the impacts of different external and internal factors on the brain, and more generally on the human body. Scaffolding Theory of Aging and Cognition proposes that during life the brain develops specific neural networks to handle with cognitive activities. When these networks are impaired due to factors that damage brain structure and/or brain functioning, the brain adapts and elaborates new networks to cope with this situation. A cognitive reserve built throughout life and an appropriated care such as for example cognitive training, are in the centre of this model because they are involved in building these networks. In general, studies exploring cognitive training in normal aging and in patients suffering from neurodegenerative disease such as Alzheimer's disease have shown some benefits of the training on cognitive functioning. It has been shown not only that the cognitive training improves older adults' cognition, but also that these effects last for a long time and positively influence older people everyday activities. In fact, the benefits from memory training were observed 5 years after the end of the training and those of reasoning and of speed of processing even after 10 years. In addition, majority of the participants declared to notice improvement of their everyday life. Concerning Alzheimer's disease, several studies have observed positive results of cognitive training although there are some controversies about its' effects. Numerous studies point out that for cognitive training being the most efficient, the intervention has to take place as early as possible, preferentially in a premorbid stage of the disease and that it is important to propose trainings that minimize the withdrawal. In this sense, the importance of using computer based training was put forward because it allows the elaboration of multiple exercises with playful aspect and more importantly it can adapt on line the difficulty of the exercises to the patient's performance. However, if it is commonly admitted that computer based training has an important role in physician's, psychologist's or speech therapist's office less is known about the efficiency of this type of training performed at distance, at the patient's place of residence. It seems probable that to propose distance training as an additional training to that performed in a practitioner's office would increase training benefits. To investigators knowledge this was not investigated in a systematic way with Alzheimer's disease patients. The more important advantages of a such additional training are: (1) reduction of patients' travelling, (2) increased flexibility of training scheduling and (3) increased frequency of training sessions per week.
Thus, in the present study investigators will examine in a systematic way, whether the distance training, as an additional training to this performed in practitioner's office, brings incremental short- and long-term benefits coming from cognitive training in mild to moderate Alzheimer's disease patients. Investigators second objective is to determine what would be the best frequency per week of such an additional training.
