About this study

BrainCheck's battery of 12 cognitive assessments will be used in this study, which aims to measure a variety of cognitive domains (memory, attention, mental flexibility, executive function, processing speed, balance, reasoning, visuospatial construction, language, and visual hallucinations).

With the decline in cognition occurring at a quicker rate at older ages, this study aims to collect additional data from healthy older adults to better capture the normative distribution among these age groups from existing and new assessments.

Treatment and study plan

BrainCheck Assessment

Device

A computerized neurocognitive test administered via an electronic device, such as a phone, tablet or computer, that contains several assessments that will aid in establishing an individuals cognitive performance

Primary outcomes

Mean, standard deviation, and percentiles of values of BrainCheck Assessments

Time frame: 5 months

BrainCheck Assessment values will be calculated by descriptive statistics. Mean, standard deviation, and percentiles (1, 5, 10, 25, 50, 75, 90, 95, 99) of the scores will be calculated for each individual assessment.

Secondary outcomes

Test-retest reliability of BrainCheck Assessment values between two different time points

Time frame: 5 months

Evaluate the test-retest reliability of BrainCheck assessments using Pearson Correlation coefficients on the descriptive statistics of each individual assessment.
