What is being measured
The primary outcome is the main question the study is designed to answer.
Pre-post variability of normal, MCI and dementia at both points of the study.
Through standard deviation of normal subjects, MCI and dementia, variations in language are measured by considering MMSE scores and the most significant variables of accexible's tests (image description test, phonetic verbal fluency test and semantic verbal fluency test).
Measured: Change from the baseline cognitive function at 9 months.
Secondary outcomes (1)
Correlation between cognitive tests and language variables obtained by the platform.
Correlation between: Standard measures of cognition (e.g., MMSE score) + behavioral and psychiatric symptoms of mild cognitive impairment and language.
Measured: Every 6 to 9 months

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pre-post variability of normal, MCI and dementia at both points of the study. (time frame: Change from the baseline cognitive function at 9 months.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
