Dementia, Mild Cognitive Impairment
Conditions
Brief summary
Dementia, especially dementia caused by Alzheimer's disease, is considered one of the most severe health problems of our time. It is currently known that the disease begins many years before clinical symptoms appear. The sooner the patient is diagnosed, the sooner the patient will be in a position to prevent further deterioration. A recent orientation is the analysis of language in relation to the description of images with a high and varied semantic and emotional content. It can be studied that changes in the description of an image check if these changes are associated with the evolution of a person with probable impairment both in memory and cognitive as well as emotional, psychiatric, behavioral and even in their interaction with environmental factors especially those associated with socialization and loneliness. Thus, the purpose of this study is to validate speech analysis AI models.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Vocal biomarkers to assess pre-post variability of normal, MCI and dementia at both point of the study. | Change from the baseline cognitive function at 9 months. | Standard deviation of normal subjects, MCI and dementia to measure variations in language by using vocal biomarkers. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between standard cognitive test (MMSE) and linguistic variables obtained by vocal biomarkers. | Through study completion, an average of 1 year. | With a 95% confidence interval, the correlation between standard cognitive test (MMSE score) and each of the linguistic variables is quantified. |
