Language training auxiliary system and method based on residual memory of senile dementia

Abstract

The invention discloses a language training auxiliary system and method based on the residual memory of senile dementia, which establishes a personalized patient database that may be well known in thelong-term memory of AD patients and provides five training modules of assisting naming, assisting memorizing poems and patter, asking questions and answering, guiding singing and filling in the blanks. The AD patient personalized database is used as the input of the intelligent training scheduling module to generate training content metadata. The training content metadata is processed by the above five training modules to generate specific training content details, and interactive training is carried out with AD patients through the interactive module. The invention uses the remaining memoryto regain the patter, poems, songs and the like preserved in long-term memory and with good connection function, so as to carry out language expression training on patients and train language expression ability without increasing language work burden. Thus, the mental pressure and nervousness caused by the language barrier are reduced.

Description

technical field [0001] The invention relates to the technical field of geriatric nursing and system functional linguistics, in particular to a language training auxiliary system and method based on the residual memory of senile dementia. Background technique [0002] Alzheimer's Disease (AD), also known as Alzheimer's disease, is a neurodegenerative disease associated with ageing, with insidious onset and progressive development, mainly manifested as chronic progressive cognitive function degradation. The fourth largest "killer" that endangers the health of the elderly. With the increasing aging of the population, the incidence of AD is increasing. It is estimated that in 2050, the number of AD patients in my country will exceed 20 million. The pathological changes of AD are the formation of a large number of amyloid deposits between neuronal cells in the brain, the existence of neurofibrillary tangles in the nerve cells, and the neurofibrillary tangles cause the destructio...

AI Technical Summary

Problems solved by technology

The course of AD can last for more than 20 years. After entering the middle stage, it completely loses the ability to learn and recall new information, but the long-term memory has not been completely lost. The first symptom of AD in the early stage is loss of recent memory. Affected by the loss of recent memory, it appears early Impairment of language function, mainly manifested as difficulty in vocabulary retrieval, difficulty in naming, vocabulary drive, sudden topic change, linear progression and repetitive progression

However, the long-term memory of early AD patients is better than the short-term memory. In the conversation, the "partial coherence" and continuous discourse between the upper and lower sentences are still good.
