Cognitive impairment affects 40 to 70% multiple sclerosis patients. This condition is characterized by slower information processing, associated with deficits in episodic memory, attention and executive functions. These disorders appear early, regardless of functional impairment, in benign forms and in clinically isolated syndromes of multiple sclerosis. These disruptions can have a significant impact in the socio-professional and personal life of patients and also in the quality of life (job loss risks, daily activities limitations).~Even if these disorders are now well documented, remediation strategies remain less studied. Some studies show that the training methods, often used, do not seem suitable for clinical monitoring, with benefits that do not persist over time. Despite their impact on daily life, no specific care for planning abilities, mental inhibition and flexibility, or even social cognition, have been well studied until today. The same is true concerning metacognitive abilities. Finally, remedial techniques are time consuming and difficult to adapt to patients still in professional activity.
The main goal of this study is to assess the effectiveness of a cognitive remediation program based on a serious game on the information processing speed evolution and the process of learning via episodic memory in multiple sclerosis patients.
