Brief summary
The SPARK Cognitive Status Indicator software uses an algorithm to assess a resting state EEG recording as being consistent with a cognitive status of unimpaired, mild cognitive impairment (MCI; MCI AD- or MCI AD+), or dementia (dementia AD-, or dementia AD+). This study will compare SPARK Cognitive Status Indicator output to Adjudication Committee panel-based diagnosis of cognitive status and Alzheimer's disease.
Detailed description
Up to 600 subjects (and informants) may be enrolled and have a brain scan, cognitive, and blood assessments collected: Visit 1-Screening: -Salzburg (SDTP)- remote via telephone or video visit Visit 2/3-Evaluations: * EEG Scan (brain scan) * Mini-Mental State Exam (MMSE)-at home visit * Functional Assessment Staging Tool (FAST)- at home via video visit * blood- Amyloid Beta 42/40 ratio, p tau- at laboratory or home visit There are three instances of subject engagement with the study team after informed consent. One, during screening which may be a remote visit and and two different home or remote visits (or laboratory visit). The study participation ends when all of the assessments have been collected. The total duration of subject participation should be no more than 2-3 days within a 90 day period. The output of the investigational software used in the analysis to determine a identification of cognitive and Alzheimer's status based the data from the EEG scan shall be compared to the identification of cognitive and Alzheimer's status from a group of dementia specialists forming an Adjudication Committee which shall review all data (except for investigational device output).
Interventions
DIAGNOSTIC_TESTSPARK Cognitive Status Indicator (software support data collected via EEG)
The SPARK Cognitive Status Indicator software (collected via EEG) is being validated to aid in the diagnosis of Alzheimer's disease in persons aged 65-90 with suspected cognitive impairment. The device, once validated, shall provide a clinician with a positive or negative output to indicate whether the subject's electroencephalogram (EEG) is consistent with EEGs of subjects diagnosed with Alzheimer's disease.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of SPARK Cognitive Status Indicator compared to Adjudicated cognitive status | Day 1 | Software output of investigational device shall be compared to the cognitive status as determined by an Adjudication Committee |
| Sensitivity of SPARK Cognitive Status Indicator when identifying Alzheimer's disease in impaired subjects | Day 1 | Software output sensitivity will be computed from device AD+ output compared to the Adjudication Committee findings of AD positive cases (MCI and dementia subjects) |
| Specificity of SPARK Cognitive Status Indicator when identifying Alzheimer's disease in impaired subjects | Day 1 | Software output specificity will be computed from device AD- output compared to the Adjudication Committee findings of AD negative cases (MCI and dementia subjects) |
