Detaljeret beskrivelse
This open-label, single-arm clinical trial aims to evaluate the efficacy and safety of Temporal Interference (TI) stimulation targeting the bilateral amygdala in patients with post-traumatic stress disorder (PTSD).
All enrolled patients receive active TI stimulation delivered twice daily for 20 minutes per session over 7 consecutive days, followed by follow-up assessments for up to 3 months. Comprehensive clinical assessments, self-reported symptom scales, magnetic resonance imaging(MRI), magnetoencephalography(MEG),electroencephalography (EEG), and cognitive function tests are conducted before and after the treatment to ensure data consistency.

Beskrivelse
Inclusion Criteria:
- Age 18-50 years, male or female
- Diagnosis of PTSD per DSM-5 (assessed by CAPS-5), with symptom duration of at least 3 months, and PTSD as the current primary diagnosis; comorbid depressive disorder or anxiety disorder is allowed
- If currently receiving psychiatric medication, the dosage must be stable for at least 4 weeks prior to enrollment
- At least 9 years of education (junior high school or above)
Exclusion Criteria:
- Any DSM-5 diagnosis other than PTSD, depressive disorder, or anxiety disorder
- PTSD symptoms too severe to complete required assessments
- Received electroconvulsive therapy (ECT) within the past 6 months
- Received any other form of neuromodulation within the past 2 months (see Item 3 for ECT)
- Severe medical illness or any condition that may induce seizures or intracranial hypertension (e.g., cardiovascular or respiratory diseases)
- History of neurological disorders (e.g., epilepsy, cerebrovascular accident) or brain injury/surgery
- Presence of intracranial stents, cardiac pacemakers, coronary stents, cochlear implants, or any other MRI-incompatible implants
- Current significant suicidal behavior risk per investigator judgment
- Pregnancy or planning to become pregnant during the study period
- Initiation of structured psychotherapy for PTSD within 3 months prior to screening, with expected change during the 10-week treatment period

Eksperimentel: Bilateral Amygdala Group (BLA-TI)
Open-label, single-arm.
Participants receive active Temporal Interference (TI) stimulation targeting the bilateral amygdala.
Stimulation is delivered twice daily (20 minutes per session) for 7 consecutive days.
Parameters: carrier frequencies 2000 Hz and 2160 Hz, envelope frequency 160 Hz, intensity 3-4 mA (adjusted to individual tolerance).
Target localization is performed using each participant's MRI data to construct an individualized 3D head model, generating scalp stimulation coordinates for the bilateral amygdala.
|
The TI stimulation device delivers temporally interfering electrical fields with a 160 Hz envelope frequency, generated by high-frequency carrier waves (2000 Hz and 2160 Hz).
Stimulation is applied for 20 minutes per session, with a peak current of 3-4 mA per channel, adjusted based on individual tolerance.
The stimulation target is the bilateral amygdala.
Stimulation is administered twice daily, with the treatment phase lasting 7 consecutive days.

post-traumatic stress disorder symptoms improvement
Tidsramme: Baseline, immediately post-treatment (Day 7), and at follow-up visits (Week 1, Week 4, Month 3 post-treatment)
|
PTSD symptom severity will be assessed using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), a clinician-rated structured interview with a total severity score range of 0 to 80. Higher total scores indicate more severe post-traumatic stress symptoms.
