Eligibility Criteria

Age 25 - 60 · Male Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Patients must be taking their current medication for at least 2 months before implantation and agree not to increase the dosage or add any new medications for the first 6 months of the study, unless it is medically necessary.
Stage 2 level of treatment resistance as per Sippel et al.136 refers to a clinical record that documents failure to respond to adequate (minimum 3 month, with adherence) trials of at least 3 of the following evidence-based treatments including at least one pharmacologic agent below, and at least one trauma-focused individual cognitive-behavior psychotherapy among the following: Pharmacologic: sertraline, paroxetine, fluoxetine or venlafaxine, at maximally tolerated FDA recommended doses
The person has had a minimum baseline past month CAPS-5 score of 47, with full PTSD diagnostic criteria met, and scores of ≥ 3 on at least one item from the intrusive (CAPS-5 items 1-5) and hyperarousal (CAPS-5 Items 15-20) clusters
PTSD is the most common diagnosis among people who experience chronic or treatment-refractory distress
Some patients who are unable to complete trauma-focused psychotherapy may be included in the study if they began treatment, but had to stop because the risks of continuing treatment outweighed the potential benefits.
All psychotherapy for PTSD that is backed by evidence must be completed at least three months before someone can enroll.
The man is between the ages of 25 and 60 years old.
The patient had the ability to give consent in accordance with institutional policies and participated in the 4-year follow-up, involving assessments and stimulator adjustments.
The study psychiatrist confirmed that PTSD was the primary psychiatric diagnosis after interviewing the patient and using the CAPS.
A person must have had a minimum of 5 years of illness, with no 6-month period of remission during the 2 years prior to study entry.
