German Registry of Alzheimer's Disease Treated With Transcranial Pulse Stimulation (GE-R-A-TPS)

July 15, 2026 updated by: Heinrich-Heine University, Duesseldorf

German (GE) Multicenter Prospective Data Collection (Registry) on Treatment With Transcranial Pulse Wave Stimulation (TPS) in Patients With Alzheimer's Disease (A)

This study will primarily investigate the safety and secondarily the effect and applicability of Transcranial Pulse Wave Stimulation (TPS) for the treatment of Alzheimer's disease in the context of a PMCF study (Post-Market Clinical Follow-up). The multicenter, prospective data collection should help to optimize the stimulation protocol, as well as to record frequent to occasional adverse effects of the product and cognitive, affective and subjective scores.

Detailed Description

This study will primarily investigate the safety and secondarily the effect and applicability of Transcranial Pulse Wave Stimulation (TPS) for the treatment of Alzheimer's disease in the context of a PMCF study (Post-Market Clinical Follow-up). The multicenter, prospective data collection should help to optimize the stimulation protocol, as well as to record frequent to occasional adverse effects of the product and cognitive, affective and subjective scores. Adverse effects and adverse events without a clear causal relationship will be documented in terms of frequency and severity. Furthermore, the progression of improvement in Alzheimer's symptoms as a result of TPS treatment is summarized in various neuropsychological scales.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

AD Patients undergoing TPS

Description

Inclusion Criteria:

i. Age = 18 to 85 ii. N>=100, clinical Alzheimer's syndrome, defined by a gradually progressive change in memory function (for severity using the MMSE as a screening tool) and impairment of activities of daily living for more than six months iii. MRI scan, in vivo evidence from CSF and/or PET using the NIA-AA criteria, which categorize the underlying pathological processes based on biomarkers, should be added if possible, but are optional. These biomarkers are categorized as ß-amyloid deposition, pathological tau and neurodegeneration [AT(N)], which can be detected on imaging and in biofluids. If possible, patients with Alzheimer's disease (AD) or Alzheimer's continuum should be included.

iv. TPS treatment in a center of a neurological or psychiatric specialist and performed under supervision of a specialist

Exclusion Criteria:

i. Relevant intracerebral pathologies not related to Alzheimer's disease, such as vascular encephalopathy Fazekas grade 3, tumors, vascular malformations, pregnancy, metal implants, CAA according to Boston criteria, Z.n. or during antibody therapy ii. Blood coagulation disorders or oral anticoagulation iii. Epilepsy iv. Medical conditions leading to non-compliance with the protocol

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Measure Description
Time Frame

Time Frame: through study completion, an average of 1 year
