Brief Summary:
The current study is intended to enrich and extend the database of Alzheimer's Disease (AD) and healthy control (HC) MEG scans and will include patients meeting DSM-IV-TR criteria for dementia of Alzheimer's type, and age- and gender-matched HC subjects meeting criteria of normal neurological function. This study will include 2 MEG and electroencephalography (EEG) scans on approximately 80 AD subjects and 80 HC subjects over approximately 30 days. All subjects will have MEG/EEG scans at baseline and 28 - 35 days after baseline. Within one day of each scan visit AD subjects will undergo 4 standard functional tests while HC subjects will undergo 2 standard functional tests.
This study will test the following hypotheses:
* MEG scans of resting-state, eyes-open brain function reveal patterns of correlated activity that differ between HC subjects and subjects diagnosed with dementia of Alzheimer's type;
* Patterns of correlated activity measured in AD subjects correspond to other measures of disease severity such as standard functional test scores;
* MEG scan patterns for HC subjects are consistent across repeated measures taken over a 30 day period.

Detailed Description:
This study is intended to extend the capabilities of the Synchronous Neural Interaction® (SNI) test, which is under development by the sponsor, Orasi Medical, Inc. Magnetoencephalography (MEG) is an FDA-approved, non-invasive technique used to measure magnetic fields generated by small intracellular electrical currents in neurons. The SNI test evaluates brain function and dysfunction by analyzing brief (1 minute) MEG scans and comparing individual scan results to a database of MEG scans and clinical information. Proprietary software algorithms process the data generated by MEG instruments allowing Orasi to use the SNI test for accurate tracking and diagnosis of neurological disorders such as Alzheimer's disease (AD) and Multiple Sclerosis (MS). The current study is intended to enrich and extend the database of AD and healthy control (HC) MEG scans and will include patients meeting DSM-IV-TR criteria for dementia of Alzheimer's type, and age- and gender-matched HC subjects meeting criteria of normal neurological function. This study will include 2 MEG and EEG scans on approximately 80 AD subjects and 80 HC subjects over approximately 30 days. All subjects will have MEG/EEG scans at baseline and 28 - 35 days after baseline. Within one day of each scan visit AD subjects will undergo 4 standard functional tests while HC subjects will undergo 2 standard functional tests. The results generated in this study will be used to improve the accuracy of the SNI test for diagnosing and tracking the progression of AD. Once a robust training set or template is described, Orasi Medical will conduct additional clinical studies to formally test the diagnostic accuracy of the technology and support applications for regulatory approval to market the SNI test for AD. The objective of this work is to produce and validate a novel tracking and diagnostic technology for AD that is more selective and sensitive than currently available diagnostic tools.
