Description

Brainwave-Based Rehabilitation Training System for Cognitive Impairment The present invention relates to a brainwave-based cognitive impairment rehabilitation training system that identifies the degree and grade of individual cognitive impairment based on brainwave signals and provides personalized cognitive impairment rehabilitation training content corresponding thereto, thereby moving away from conventional uniform training methods and providing personalized training content optimized for each individual. This not only enhances interest and immersion in the cognitive impairment rehabilitation training content but also further improves the efficiency of cognitive function rehabilitation through motivation, such as providing reward measures. Generally, cognitive impairment refers to a state in which memory, attention, language ability, visuospatial ability, and judgment are impaired. The severity varies from very mild to severe, and in cases of severe cognitive dysfunction, it can interfere with daily life and social activities. In other words, cognitive impairment is a brain disorder characterized by impairment of overall cognitive function while conscious, usually caused by chronic or progressive brain disease, and is a syndrome in which impairment occurs in multiple higher cerebral functions such as memory, thinking, understanding, calculation, learning, and language judgment. On the other hand, mild cognitive impairment refers to a condition where cognitive function, particularly memory, is lower than that of the same age group, but the ability to perform daily activities is preserved. This can be considered an intermediate stage between normal and severe cognitive impairment; as the earliest stage detectable through testing, it is known to maximize the effectiveness of treatment. Recently, various programs such as puzzle games, drawing, and storytelling to activate the brain have been proposed as measures to prevent and treat cognitive impairment-related diseases. However, despite these efforts, conventional cognitive training programs aimed at preventing and treating various cognitive impairments are failing to generate interest among patients and are mostly conducted using uniform training methods, so they are not achieving effective results.
