About This Trial

To investigate the safety of deep brain stimulation (DBS) and cervical deep lymphoid-venous anastomosis (LVA) in the treatment of severe Alzheimer's disease (AD); to investigate the effectiveness of DBS and LVA in the treatment of severe AD, i.e., effects of deep brain stimulation on cognitive function, emotion and life quality in patients with severe AD.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Alzheimer Disease, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 98 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Alzheimer Disease subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Treatments Being Tested

PROCEDURE

Deep Brain Stimulation, DBS

Deep brain stimulation (DBS) is performed after preoperative MRI and CT images are fused in a planning system to determine the target and trajectory. Under general anesthesia, electrodes are precisely implanted into the fornix or nucleus basalis of Meynert using a stereotactic frame or neurosurgical robot. The electrodes are inserted through a burr hole in the patient's skull and connected to a pulse generator placed subcutaneously in the chest. Optimal stimulation parameters for Alzheimer's disease are not yet established. For fornix targets, settings are typically 3-3.5 V, \~130 Hz, 90 μs; for nucleus basalis targets, 2-4.5 V, 10-20 Hz, 90-150 μs, adjusted according to anatomical features and intraoperative responses.

PROCEDURE

Deep cervical lymphatic-venous anastomosis, LVA

Cervical deep lymphaticovenous anastomosis (LVA) microsurgically connects deep cervical lymphatic vessels to adjacent veins, promoting drainage of brain-derived amyloid-β and tau into the venous system and potentially alleviating Alzheimer's disease symptoms. The minimally invasive neck procedure involves small incisions and high-magnification suturing of lymphatics and veins with ultra-fine (11-0 or 12-0) sutures, creating multiple anastomoses to enhance brain lymphatic outflow.

DRUG

Recognized pharmacological treatments for AD.

Patients in the medication group received only the currently recognized pharmacological treatments for AD, including Memantine Hydrochloride and Donepezil.
