Low-Intensity Focused Ultrasound (LIFU) Neuromodulation

Summary

This study is a prospective, single-center, single-arm early feasibility study, to establish safety and tolerability of LIFU for neuromodulation in patients with mild cognitive impairment ( MCI) due to Alzheimer's disease.

Eligibility

Inclusion Criteria:

* Males and non-pregnant females, aged 45-85 years
* Able and willing to give informed consent

* If receiving concurrent treatment with an AChEI and/or memantine, has been on a stable dose for at least 45 days
* Able to communicate sensations during the LIFU procedure

Exclusion Criteria:

* Unable to undergo MR-imaging because of implanted pacemakers, medication pumps, aneurysm clips, metallic prostheses (including metal pins and rods, heart valves or cochlear implants), shrapnel fragments, permanent make-up or small metal fragments in the eye that welders and other metal workers may have, or if candidates are uncomfortable in small spaces (have claustrophobia).
* Participants with more than 30% of the skull area traversed by the sonication pathway are covered by scars, scalp disorders (e.g., eczema), atrophy of the scalp, or implanted objects in the skull or the brain.
* Participants with a history of seizure disorder.
* Participants with clinically significant chronic pulmonary disorders e.g., severe emphysema, pulmonary vasculitis, or other causes of reduced pulmonary vascular cross-sectional area.
* Participant does not speak English
