NCT07060391

Brief Summary

This research aims to observe the efficacy and safety of surgery compared with traditional medical treatment for moderate to severe dementia in Alzheimer's disease. This is a prospective multicenter RCT clinical research, involving a total of 3 research centers.Patients diagnosed with Alzheimer's disease accompanied by moderate to severe cognitive dysfunction in these three hospitals from January 2025 to January 2027 were included. This research is expected to recruit a total of 186 patients with moderate to severe Alzheimer's disease.93patients received conventional medical treatment, Deep cervical lymphatic-venous anastomosis was performed in 93 patients.Comprehensively evaluate the efficacy and safety of the patients within 48 weeks after treatment.

Outcome Measures

Primary Outcomes (1)

  • ADAS-cog score

    The improvement of 4 points by ADAS-cog is used as the judgment criterion for the clinical therapeutic effect, Compare the remission rates between the experimental group (surgery) and the control group (medication).

    baseline,48 weeks

Secondary Outcomes (5)

  • Imaging data

    From the first week to the 48th week

  • Cerebrospinal fluid examination

    From the first week to the 48th week

  • Markers of Alzheimer's disease in the blood

    From the first week to the 48th week

  • Surgery-related adverse reactions

    From the first week to the 48th week

  • Quality-Adjusted Life Year

    From the first week to the 48th week

Study Arms (2)

Surgical treatment

EXPERIMENTAL

Deep cervical lymphatic-venous anastomosis

Procedure: Deep cervical lymphatic-venous anastomosis

Internal medicine conservative treatment

PLACEBO COMPARATOR

Donepezil drug ,5-10mg,qd,po. All patients stopped taking cognitive-enhancing drugs and marketed therapeutic drugs such as ginkgo, high-dose vitamin E, lecithin, estrogen, non-steroidal anti-inflammatory drugs, Memegan, etc. after enrollment.

Drug: Donepezil drug treatment

Interventions

Lymph node reconstruction was carried out using microsurgical techniques,improve cerebral lymphatic circulation and return, accelerate the excretion of pathological proteins, the metabolic products of the brain, from the brain. This is to delay the degenerative changes of the brain and the progression of Alzheimer's disease.

Surgical treatment

All patients stopped taking cognitive-enhancing drugs after enrollment, and marketed therapeutic drugs include ginkgo biloba, high-dose vitamin E, lecithin, estrogen, non-steroidal anti-inflammatory drugs, memegan, etc.

Internal medicine conservative treatment
