Overview
Brief Summary
This follow-up study is designed to obtain longitudinal clinical and MEG scan data to gain information on Alzheimer's disease (AD) progression, the stability of healthy control (HC) MEG scan data, to enrich the Orasi database of AD and HC subjects, and is intended to extend the capabilities of the Synchronous Neural Interaction® (SNI) test, which is under development by the sponsor, Orasi Medical. The current study is intended to extend the database of AD and HC MEG scans and will include patients who previously enrolled and completed Orasi Protocol ADG 08-01. This study will include MEG scans on up to approximately 50 AD subjects and 70 HC subjects. Additionally, AD subjects will complete 3 standard functional tests while HC subjects will complete 2 standard functional tests. ApoE genotyping also will be determined for all subjects. 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.

- •Informed Consent for details.
- •Subject is a non-smoker.
- •Subject is judged to be in good health other than AD, if applicable
Exclusion Criteria
- •Subject has a history or diagnosis of a significant neurological condition other than Alzheimer's disease including Parkinson's disease, vascular dementia, Lewy body dementia, frontal temporal dementia, human immunodeficiency virus, multiple sclerosis, seizures, epilepsy, stroke, ADHD, dyslexia, or severe traumatic brain injury.
- •Subject has a history of primary psychotic disorder (e.g. schizophrenia, schizoaffective disorder, delusional disorder) or bipolar disorder.

- •The subject has a recent history (within 2 years) of alcohol or substance abuse/dependence.
- •Subject had an MRI within two weeks prior to Study Visit
- •Subject has metal dental braces, pacemaker or other common medical devices that may interfere with the MEG scan.
- •Subject is unable to complete the MEG scan procedure.
- •Investigator has any concern regarding the safe participation of a subject in the study, or if for any other reason the investigator considers the subject inappropriate for study participation
