Cognitive Effects of Theta-burst Stimulation (TBS) in Suspected Non-Alzheimer Disease Pathophysiology (SNAP) (SNAP)
February 7, 2024 updated by: Chang Gung Memorial Hospital
Cognitive Effects and Potential Mechanisms of Theta-burst Stimulation (TBS) in Suspected Non-Alzheimer Disease Pathophysiology (SNAP): a Pilot Study
This is a pilot study to identify a homogeneous cohort of pathologically specific dementia with SNAP for clinical trial of brain stimulation.

Enrolling by invitation
Intervention / Treatment
Detailed Description
The investigators apply the NIA-AA criteria to identify the individuals of biomarker-defined SNAP endophenotype.
This is a prospective, randomized controlled clinical trial for the first two weeks, followed by an open-label trial for the next two weeks, and combined functional neuroimaging study of 18F-FDG-PET to further explore the potential mechanisms.
A total of 20 SNAP dementia patients will be recruited for consecutive two years, and be subjected to iTBS for 5 daily interventions per week for four consecutive weeks.
Cognitive evaluation will be performed before and immediately after TBS intervention, and 8 weeks after TBS.
Data on functional neuroimaging will be also collected before and after TBS protocol.

Description
Inclusion Criteria:
- Subjects aged 50-90 year.
- Patients meet NIA-AA research criteria for suspected non-Alzheimer disease pathophysiology (SNAP) (Petersen, Smith et al. 1999; Jack, Bennett et al. 2018), and DSM-5 criteria for major neurocognitive disorder of dementia (Regier, Narrow et al. 2013).
- Amyloid PET should ever be performed.
- The CDR of subjects can be 0.5-2.
Exclusion Criteria:
- Any subject has a definite diagnosis of epilepsy or history of seizure attack.
- Current or past history of clinically significant neurological insults affecting brain structure or function like completed stroke, head injury or brain tumor. (cerebrovascular disorders, hydrocephalus and intra-cranial mass, documented by MRI; a history of traumatic brain injury or another neurological disease).
- Any subject has clinically significant or unstable medical diseases including metabolic, renal, liver, lung or cardiovascular disorders including metabolic, renal, liver, lung or cardiovascular disorders.
- Any subject has current alcohol or other substances abuse and/ or dependence within the recent one year, or prolonged history of major psychiatric disorder like schizophrenia, bipolar disorder, and previously prolonged substances abuse.
- Any females who is pregnant or lactating.
- General MRI, TMS and/or PET exclusion criteria including subjects who had received brain aneurysm surgery, or implanted pacemaker, mechanical valves, cochlear implant or other metal devices/ objects that are not MR compatible in the body.
Withdrawal criteria
- Complications onset after intervention that affect efficacy and safety judgments.
- New onset or progression of disease that may affect outcomes.
- Use of other therapies or drugs during the intervention period to change cognitive functions.
- Any subjects who are recognized as high risk of adverse effects by principle investigator.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: active and active
The patients will be subjected to TBS for 5 daily interventions per week for four consecutive weeks.
|
The investigators will perform standard intermittent TBS (iTBS) parameters to left DLPFC of every patient in the study.
The frequency parameters of TBS are 3-pulse 50- Hz bursts, every 200 ms at 5 Hz, and the intensity is 90% of active motor threshold.
A single session of iTBS contains 2 s of TBS repeated every 10 s for 20 times.
In this study, The investigators will give two sessions of iTBS separated by 15 min.
|
Sham Comparator: sham and active
The patients will be subjected to TBS for 5 daily interventions per week for the first two weeks, followed by an open-label trial for the next two weeks.

A single session of iTBS contains 2 s of TBS repeated every 10 s for 20 times.
In this study, The investigators will give two sessions of iTBS separated by 15 min.
Sham stimulation applies the same iTBS protocol with the sham coil.
