Description of the Invention [Technical Fields of the Invention] The present invention provides a technical field of a simulation space and an evaluation system, and more particularly, to provide a spatial cognitive ability evaluation method and system for dementia, by which the system and method are Evaluate the state of intelligence and then determine the severity of dementia. 〇 〇 [Prior Art] The Morris water maze was designed for mouse experiments in the design of Morris. It mainly describes the development of the behavioral pattern of the mouse's spatial orientation. The experimental procedure is to place the mouse in a large circular sink. The mouse can leave the environment by a hidden platform in the pool. The first experiment places the platform below the water surface. The second experiment is about the pool. For turbid opaque liquids, the platform is hidden, while this does not provide any hints to help the mouse. In principle, the mouse should be arbitrarily in the process of escaping. The path of the search platform...μ疋 has no systematic trajectory. However, after the non-prepared, the normal mouse will quickly learn how to use the map from the flat point of any point around the ancient platform of the 乂 platform to swim directly toward and toward. This exact directionality can be μ # Φ ^ ρβ , . ^ to also suggest that the normal mouse can be in the two fields (and remember _ I can escape the pool, this ability has been hidden) to shorten each platform The search time of the world. The world has gradually entered the Senior Citizens Association, and its 75% of the elderly 3 200924717 will have one or more chronic diseases, and "old dementia" is a common disease. Symptoms of mental illness are staged deterioration. Early symptoms. There is a slight forgetfulness, and the way to go home does not recognize the way home. In the medium term, it will gradually enter a state of insanity and memory loss, even if it is near the home, it can be lost. This is Symptoms that most family members are worried about. • It is estimated that the prevalence of dementia in the developed countries is about 3% to 6%. However, in the past, the traditional methods for assessing dementia were mostly filled with the paper's dementia scale. The SCDR of the Intelligence Scale needs to be assisted by professionals, and the results of the MMSE assessment are also affected by the educational level. The filling process of the test questions is also boring. [Invention] Technical problems to be solved · In the past, traditional methods for assessing dementia were mostly filled with the paper's dementia scale.

This example is Ο ❹: results of different status group analysis : It is a young person (Η), an annual person, (5 1) has better spatial cognition ability, so it is possible to learn the position of a platform in a dilemma. The other is a normal old man (5" The normal elderly (5 2 ), although the spatial learning ability and response are slow, but their spatial cognitive ability has not been lost, so the curve declines slowly, and finally the relationship between the space can be memorized, and then the platform can be quickly found. : For the elderly with dementia (53) 'The demented tendency to the elderly (53) because of the loss of spatial cognitive ability, so after many tests, the learning curve is still high. With such a test, The step determines the difference between the spatial cognition and learning ability of the three types of subjects, and further proves that the elderly with dementia tend to have symptoms of loss of spatial cognition. See the sixth figure to get the first stage of loss. After the assessment of intellectual orientation, S has recorded the time of the test, the length of the track and the number of times across the quadrant.
