Problems solved by technology

However, the existing detection methods for cognitive impairment are time-consuming and costly, and cannot be popularized and used in a large-scale elderly population. Moreover, the existing methods require the testees to go to a special hospital department to receive the test. Potential Most patients with cognitive impairment often do not know that they have this disease at the early stage of the disease, and they do not go to the hospital for examination until the disease is more serious, or even developed into dementia, and the best time for early detection is missed

[0090] see figure 1 , is a schematic flowchart of a cognitive assessment method provided in this embodiment, the method includes the following steps:

[0091] S101: Record the sound data of the person to be detected within the target time period.

[0092] In this embodiment, any person to be tested who implements cognitive assessment in this embodiment is called a person to be tested. Elderly people with cognitive impairment can also be normal people with severe cognitive impairment or without cognitive impairment.

[0093] In order to evaluate the cognitive status of the subject to be detected conveniently, quickly and at low cost, it is first necessary to record the sound data of the subject to be tested within the target time period, wherein the target time period can be set according to the actual situation, for example, the If the target time period is set to 24 hours, then correspondingly, the sound data of the person to be detected within 24 hours can be recorded. It ...

[0139] It should be noted that, in addition to recording the sound data of the person to be detected within the target time period (ie, the first type of data and the second type of data) in step S101 of the first embodiment, within the target time period, it is also possible to record The voice data of the conversation partner of the person to be detected, and the voice data of the conversation partner can reflect the cognitive status of the person to be detected from the side. For example, when the speech comprehension ability of the person to be tested declines and he cannot quickly understand faster speech, the conversation partner will have to slow down the speech speed, change the tone, repeat it many times, etc. Thus, the first characteristic data corresponding to the subject to be detected can be combined with the characteristic data related to the conversation partner to more accurately evaluate the cognitive status of the subject to be detected.

[0204] This embodiment will introduce a cognitive assessment device, and for relevant content, please refer to the above method embodiments.

[0205] see Figure 6 , which is a schematic diagram of the composition of a cognitive assessment device provided in this embodiment, the device 600 includes:

[0206] Sound data recording unit 601, for recording the sound data of the person to be detected within the target time period;

[0207] A feature data extraction unit 602, configured to extract acoustic and / or linguistic feature data from the voice data of the person to be detected as first feature data;

[0208] A cognitive status evaluation unit 603, configured to evaluate the cognitive status of the subject to be detected according to the first feature data corresponding to the subject to be detected.

[0209] In an implementation of this embodiment, the feature data extraction unit 602 includes:

[0210] The first data extraction subunit is used to filter out the first typ...

Abstract

The invention discloses a cognitive evaluation method and device. The method includes the steps that after the sound data of an object to be detected in a target time period is recorded, the feature data of the object to be detected in an acoustical aspect and a linguistic aspect can be extracted from the sound data and used as first feature data corresponding to the object to be detected, and then a cognitive condition of the object to be detected can be evaluated according to the first feature data corresponding to the object to be detected. It can be seen that the method evaluates the cognitive condition of the object to be detected based on the acoustical and / or linguistic feature data extracted from the sound data of the object to be tested, does not pass an existing cognitive assessment scale for evaluation, does not require the use of medical imaging and blood tests to rule out the effects of other diseases, and easier, faster and less costly evaluates the cognitive condition ofthe object to be detected.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a cognitive assessment method and device. Background technique [0002] Cognitive impairment, also known as mild cognitive impairment (MCI), is considered to be the first stage of Alzheimer's disease, and it can also be considered as a transition period from normal development to dementia. Patients with cognitive impairment are usually accompanied by certain short-term memory loss, and various aspects such as executive function, logical reasoning, visual construction, and language ability will be affected to varying degrees. The decline of language ability is reflected in the early stage of cognitive impairment. Typical language deficits in patients with cognitive impairment include naming difficulties, impaired comprehension of spoken and written language, fluent but empty speech and semantic aphasia. Without intervention, as the disease progresses, patients with co...
