Brief Summary

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.

Outcome Measures

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

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

Secondary Outcomes (5)

  • Change in the Neuropsychiatric Inventory total score.

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

  • Change in the Animal Fluency Test score

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

  • Change in the Disability Assessment for Dementia total score.

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

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

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

  • Change in plasma Aβ42/40

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

Study Arms (2)

Received transcranial pulse stimulation (TPS) treatment

EXPERIMENTAL

Receiving transcranial pulse stimulation (TPS) as part of an investigation into its effectiveness for improving cognitive function, memory, functional status, and neuropsychiatric symptoms in subjects with Alzheimer's Disease (AD).

Device: transcranial pulse stimulation (TPS)

Received transcranial pulse stimulation (TPS) sham treatment

SHAM COMPARATOR

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.

Device: transcranial pulse stimulation (TPS-Sham)

Interventions

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

Model Details: Participants with early AD, confirmed via blood tests, are randomly assigned to either a TPS treatment group or a placebo group. The treatment protocol involves an intensive TPS treatment period over two weeks followed by a continuous treatment period with additional treatments over some weeks. The placebo group receives sham treatment.
