About this study
The purpose of this open label study is to evaluate longer term tolerability and early efficacy of transcranial ultrasound in the treatment of patients with mild cognitive impairment or dementia.
Read the detailed description
The present study is designed as an open label study of patients with mild cognitive impairment (MCI) or dementia to evaluate longer term tolerability and early efficacy of transcranial ultrasound treatment.
Baseline and outcome measures in this study utilize validated tests that are appropriate for repeated measures which are not affected by practice effects. For patients with amnestic predominant cognitive change, the target will be the mesial temporal lobe through a trans temporal scalp window. Targeting will include reference to scalp fiducials based on the obtained MRI and Transcranial Doppler (TCD) waveform confirmation will be obtained because of the ability of TCD to record Doppler signal from the posterior cerebral artery that runs medial to the mesial temporal lobe.
On the day of the ultrasound appointment, patients will undergo ten to thirty minutes of transcranial ultrasound treatment. The sonification device will be aimed at the hippocampus or the putamen and substantia nigra, depending on the predetermined condition. Targeting will include reference to scalp fiducials based on the obtained MRI; confirmation of target accuracy will either be obtained by Doppler waveform confirmation or optical tracking technology which co-registers patient neuroimaging with real space. Patients will undergo 8 total sessions of focused ultrasound. Patients will be evaluated at baseline and upon final ultrasound treatment using the same measures obtained upon entry. Safety and any adverse events will be monitored closely.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Focused Transcranial UltrasoundDevice
The FDA has determined the power intensity limits that are safe for clinical use; the proposed equipment works within these parameters. Furthermore, monitoring sessions up to one hour as proposed in this study are routinely used in patients even with acute brain injury at 2 megaHertz without any reports of complications induced by the ultrasound device. No brain heating, cavitation or bleeding has been identified with the proposed equipment and protocol. For each individual safety can be followed by performing a selective mental status exam at each session completion (for example for hippocampal targets, there will be a delayed recall memory test).
| Study group | Role | What they receive |
|---|---|---|
| Treatment | Experimental | All patients enrolled will receive transcranial focused ultrasound. Target location is dependent on patient condition. Receives: Device: Focused Transcranial Ultrasound |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quick Dementia Rating Scale
The Quick Dementia Rating Scale (QDRS) is an interview-based tool administered by study officials to participants' caregivers used to obtain observations from a consistent source. The QDRS form consists of 10 categorical questions (5 cognitive, 5 functional), each with 5 detailed options depicting the level of impairment as either 0 (normal), 0.5 (mild/inconsistent impairment), 1 (mild/consistent impairment), 2 (moderate impairment), or 3 (severe impairment). Based on the conversion table outlined in Dr. James Galvin's research (2015), total QDRS scores were converted to Clinical Dementia Rating (CDR) scale levels ranging from 0 (normal aging), 0.5 (mild cognitive impairment), 1 (mild dementia), 2 (moderate dementia), and 3 (severe dementia).
Measured: Baseline
Secondary outcomes (5)
Repeatable Battery Assessment for Neuropsychological Status (RBANS)
RBANS assesses immediate memory, visuospatial skill, language, attention, and delayed memory. Patient performance on each subscale immediate memory, language, attention, visuospatial, and delayed memory are scored relative to validated norms for same-aged peers. A change of 8+ points in the Total Scale score, 11+ points in the Immediate Memory score, 9+ points in the Language score, 4+ points on the Attention score, 14+ points is considered significant for the Visuospatial score, and 10+ points for the Delayed Memory score are considered significant.

Measured: After final ultrasound (8 weeks from baseline)
Montreal Cognitive Assessment (MoCA)
The MoCA evaluates frontal-executive functions (e.g., verbal abstraction and mental calculation), language (e.g., confrontation naming, phonemic fluency), orientation (e.g., person, place, date, day of the week, and time), visuospatial construction (e.g., simple figure copy), divided visual attention, and immediate and delayed memory of unstructured information. MoCA scores range from 0-30 possible points; 26 or greater is considered to reflect normal cognitive status.

Questions about this trial
What is this clinical trial studying?
A study testing Focused Transcranial Ultrasound in people with Mild Cognitive Impairment and Mild Dementia, run by Neurological Associates of West Los Angeles at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 24 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quick Dementia Rating Scale (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04250376, which also lists 44 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2023.
