About this trial

TPS is a non-invasive therapeutic modality that uses focused, low-energy pulse stimulation to stimulate tissue regeneration and reduce inflammation. In the context of neurological disorders, it is hypothesized that TPS can modulate neuronal activity, enhance synaptic plasticity, and reduce neuroinflammation. It is a relatively new application in neurological disease treatment and is still under intense investigation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adults who have been clinically diagnosed with Alzheimer's Disease in the early stage 2-6a according to the Functional Assessment Staging Test (In Appendix A)

The mental capacity to give informed consent for research is made by an experienced geriatrician based on Appendix A.

Aged 60-90 years old.

Able to make informed consent under assistance, which is witnessed and signed by a family caregiver.

Disqualifiers

Cannot understand Chinese.

Mentally incapacitated, unable to provide informed consent

Inability to remain still for 30 minutes

Lack of available family caregiver to answer questionnaires

Trial design

Design model

Parallel

Treatments tested in this trial

  • transcranial pulse stimulation (TPS)

    Device

    The TPS/Sham-TPS therapy is administered for the first two weeks, followed by additional sessions at some week intervals.

  • transcranial pulse stimulation (TPS-Sham)

    Device

    Participants will undergo an identical procedure using a device that mimics the sound and sensation of active TPS but delivers no therapeutic energy pulses to the brain.

Treatment groups

40 Participants
are divided into 2 treatment groups
Group A: Received transcranial pulse stimulation (TPS) treatmentExperimental treatment 1 intervention
Group B: Received transcranial pulse stimulation (TPS) sham treatmentSham comparator 1 intervention

Trial outcomes

Primary outcomes

1

Change in Alzheimer's Disease Assessment Scale-Cognitive Subscale score.

The lower the score, the better the cognitive function; the higher the score, the more severe the cognitive impairment. Score range: 0-85

Time frame
baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)

Secondary outcomes

1

Change in the Neuropsychiatric Inventory total score.

The lower the score, the milder the neuropsychiatric symptoms; the higher the score, the more severe and frequent the symptoms, and the greater the burden on caregivers. Score range: 0-144

Time frame
baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)
2

Change in the Animal Fluency Test score

The more animal names you say within the specified time (the higher the score), the better your language fluency, cognitive processing speed, and semantic memory ability. Normal cognition typically has ≥ 15-18 (well-educated young or middle-aged individuals typically have ≥ 20). Mild cognitive impairment (MCI) may have 11-16 Dementia (such as Alzheimer's disease) typically has ≤ 12-14 , but may be lower.

Time frame
baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)
3

Change in the Disability Assessment for Dementia total score.

The higher the score, the greater the patient's functional independence and the better the ability to carry out daily life. The lower the score, the more severe the functional impairment and the greater the dependence on others for care. Score range:0-100%

Time frame
baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)
4

Change in oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (HbR) in the cerebral blood

Time frame
baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)
