On April 7-9, the 2nd Guangdong Hong Kong Macao Greater Bay Area Brain Science Summit Forum and the Guangzhou "Brain Science and Brain like Research" Academic Salon were held in Guangzhou. More than 400 experts and scholars from both domestic and foreign countries conducted intense discussions on brain science research and diagnosis and treatment.

  The key project of the National Key Research and Development Program "Active Health and Population Aging Technology Response" led by Professor Hu Xiquan from the Rehabilitation Medicine Department of Zhongshan Third Hospital - "Key Technology and System Research and Development of Assessment and Early Warning of Elderly Consciousness/Cognitive Impairment and Multi physical Factor Collaborative Stimulation Intervention" was launched simultaneously with the forum. The main focus is to demonstrate the overall framework and implementation plan of the project, ensuring the rationality, compliance, and operability of the implementation plan, ensuring that the project is well organized and laid the foundation for the organization and implementation of the project and the achievement of goals. Ultimately, a consensus was reached on the formal launch of the project, and iFlytek Co., Ltd., as a participating unit of the project, participated in this meeting.

  This project integrates cutting-edge technologies in fields such as medicine, engineering, and artificial intelligence, and conducts research from four aspects: mechanism exploration, evaluation and early warning, stimulus intervention, and application verification. Ultimately, it will establish an early warning system for cognitive decline diseases, develop a cognitive training system based on human-machine intelligent interaction, and complete the tasks of electricity, magnetism, light, sound, and force High performance fabrics and other non-invasive multi physical factor stimulation devices are used to intervene and improve diseases, and to form prevention and treatment plans, guidelines, and intervention standards for elderly consciousness/cognitive impairment. At present, the national key research and development plan has become a scientific and technological issue related to China's national economy and people's livelihood. Research on professional technical projects in the field of national economy and social development has significant strategic significance.

  According to the statistics from the 7th National Population Census in 2021, the aging population in China is becoming increasingly severe, with the number of people aged 60 and above reaching 264 million. As the aging society approaches, it is accompanied by common diseases among the elderly. Among them, elderly consciousness/cognitive impairment seriously affects the quality of life of elderly patients, which is a difficult point in the field of neurological rehabilitation. In this project, iFLYTEK aims to conduct early screening for cognitive impairment in the elderly. Based on multimodal data such as speech and writing, as well as artificial intelligence models, a multi-dimensional comprehensive evaluation early warning system will be constructed to assist in the construction of China's cognitive impairment prevention and control system. The goal is to extract key acoustic and language features used to characterize cognitive impairment by combining external knowledge such as voice physical parameter analysis and patholinguistics, Integrate the features obtained from data-driven methods to obtain a better speech feature representation for cognitive impairment, and further integrate the written features extracted from dynamic trajectory analysis to establish a high-precision cognitive degradation screening model. Design a multi-level comprehensive evaluation index system for cognitive impairment, and develop an early warning system for cognitive impairment in the elderly.
