Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this feasibility study is to evaluate the safety of DBS-f in patients with mild Alzheimer's disease by assessing all device and/or therapy related adverse events. The secondary objective is to preliminarily estimate the treatment effect size on the outcomes of interest at 12 months post-randomization. The objectives do not involve formal tests of hypotheses.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. 45-85 years of age (inclusive)
2. Probable Alzheimer's disease according to the National Institute of Aging Alzheimer's disease Association criteria.

4. If female, subjects who are post-menopausal or surgically sterile or willing to use birth control methods for the duration of the study.
5. An available caregiver willing to participate.
6. Subject is living at home and likely to remain at home for the study duration.
7. The subject is currently taking a stable dose of cholinesterase inhibitor (AChEI) medication for at least 60 days

Exclusion Criteria

1. Must meet certain criteria on cognitive and behavioral rating scales
2. Current major psychiatric disorder such as schizophrenia, bipolar disorder or major depressive disorder based on psychiatric consult at screening visit
3. History of head trauma in the 2 years prior to signing the consent to participate in the study
4. History of brain tumor, subdural hematoma, or other clinically significant (in the judgment of the investigator) space-occupying lesion on CT or MRI

9. Contraindications for MRI scanning, including implanted metallic devices (e.g. non-MRI-safe cardiac pacemaker or neurostimulator; some artificial joints metal pins; surgical clips; or other implanted metal parts), or claustrophobia or discomfort in confined spaces.
10. Abnormal lab results that, in the opinion of the investigator and/or enrollment review committee, would preclude participation in the study.
11. Abnormal cardiovascular or neurovascular disorder that, in the opinion of the investigator and/or enrollment review committee, would preclude participation in the study.
12. Unstable doses of any medication prescribed for the treatment of memory loss or Alzheimer's disease.
13. Currently prescribed any non-AD medications that, in the opinion of the investigator and/or enrollment review committee, would preclude participation in the study.
14. Is unable or unwilling to comply with protocol follow-up requirements.
15. Has a life expectancy of \< 1 year.
