Study Safety and Efficacy of Deep Brain Stimulation (DBS) and Cervical Deep Lymphoid-venous Anastomosis (LVA) in Alzheimer's Disease

This early trial tests two surgical procedures in people with severe Alzheimer's: deep brain stimulation, which uses implanted electrodes, and a lymphatic-to-vein bypass in the neck. Researchers are looking at safety first, then effects on thinking, mood and quality of life. It is a Phase 1 trial, meaning an early look at safety, not proven or approved.

  • Ability to ambulate independently or with the aid of a walker/cane.
  • Adequate visual and auditory capacity to cooperate with examinations and treatment.
  • Voluntary participation with written informed consent provided by both the subject and their legal guardian.

You're excluded if

  • Comorbidity with other neurological disorders such as multiple sclerosis, epilepsy, or Parkinson's disease.
  • Psychiatric disorders: e.g., anxiety, depression, other affective disorders, or drug-induced psychosis.

  • Severe auditory or visual impairment.
  • Clinical comorbidities with life expectancy \<2 years.
  • History of cranial surgery.
  • Contraindications to MRI or transcranial alternating current stimulation (tACS) (e.g., cardiac pacemaker, post-deep brain stimulation surgery).
  • Eczema or sensitive skin.
  • Familial Alzheimer's disease.
  • Other types of dementia: e.g., vascular dementia, Lewy body dementia, frontotemporal dementia, or infectious dementia;
  • Any other condition deemed by the investigator as unsuitable for the study
