Brief Summary
The goal of this clinical trial is to test the efficacy of transcutaneous vagus nerve stimulation (tVNS) in borderline personality disorder. The main question it aims to answer is: • Is tVNS effective in acutely reducing emotional reactivity in borderline personality disorder? Participants will be randomized to a single session of tVNS or sham-tVNS while going through an affect-inducing procedure. It will consist of the presentation of one neutral and three negative affect-inducing videos in sequence, each of which is followed by a post-induction period during which participants will rate the quality and intensity of their current self-reported emotions. Researchers will compare the tVNS and sham tVNS groups to see if there is a difference in the intensity of the self-reported emotions between the groups.

Outcome Measures
Primary Outcomes (1)
Change in negative emotional arousal from baseline at immediately after affect-induction (post-induction ratings) as assessed by PANAS
The emotional arousal will be measured through the self-reported ratings of negative emotions on the PANAS (PANAS-N). The scale uses adjectives that describe mood states rather than discrete emotions and are rated from 1 = very slightly or not at all to 5 = extremely.
Baseline and immediately after every of the four videos.
Secondary Outcomes (3)
Change in negative emotional arousal from baseline at prior to affect-induction (pre-induction ratings) as assessed by PANAS
Baseline and 4 minutes after the tVNS/sham tVNS has begun, before the affect induction procedure.
Change in negative emotional arousal from immediately after affect-induction at 4 minutes after affect induction (recovery ratings) as assessed by PANAS
Immediately after and at 4 minutes after every of the three affect inducing videos
Perceived effectiveness in managing emotions (PEME) during affect induction.
Immediately after every of the four videos
Study Arms (2)
Transcutaneous vagus nerve stimulation (tVNS)
EXPERIMENTAL1 tVNS session of ca 45 minutes The electrodes are placed at the left ear concha. The ear concha is principally innerved by the afferent branch of the vagus nerve
Sham Transcutaneous vagus nerve stimulation (tVNS)
SHAM COMPARATOR1 sham tVNS session of ca 45 minutes The electrodes are attached to the center of the left ear lobe, which is known to be free of cutaneous vagal innervation
Interventions
The electrodes are placed at the left ear concha. The ear concha is principally innerved by the afferent branch of the vagus nerve
The electrodes are attached to the center of the left ear lobe, which is known to be free of cutaneous vagal innervation
Eligibility Criteria
You may qualify if:
- Swedish-speaking and able to provide informed consent to participate in the study
- Female and between the ages 18 and 50 years old.
- Current DSM-5 (Diagnostic and statistical manual of mental disorder-5) diagnosis of BPD based on the Structured Clinical Interview for DSM-5 Personality Disorders (SCID-5-PD)
- Capable (in the Investigator's opinion) and willing to comply with all study requirements.
You may not qualify if:
- Any unstable medical and/or neurological condition
- Currently pregnant
- Any significant neurological disorder or condition likely to be associated with increased intracranial pressure or cognitive impairment (e.g., a space occupying brain lesion, a history of stroke, a cerebral aneurysm, a seizure disorder, Parkinson's disease, Huntington's chorea, multiple sclerosis)
- Current diagnosis of delirium, dementia or another cognitive disorder secondary to a general medical condition
- Established diagnosis of a developmental and neuropsychiatric disorder (e.g. Down syndrome, autism-spectrum disorder, ADHD)
- Non-correctable clinically significant sensory impairment (i.e., cannot hear or see well enough to complete the affect induction procedure, follow and answer the survey instructions and questions)
- Alcohol or substance use disorder (relating to opioids, cocaine, amphetamine or benzodiazepine) currently or within the past 1 month
- Daily treatment with antiepileptics (e.g., carbamazepine, gabapentin, lamotrigine, levetiracetam, pregabalin, sodium valproate, topiramate) or benzodiazepines (last dose over 7 days before the screening)
- Alcohol or substance use disorder (relating to opioids or cocaine) currently or within the past 1 month
- Intracranial implant (e.g., aneurysm clips, shunts, stimulators, cochlear implants, or electrodes) or any other metal object within or near the head, excluding the mouth, that cannot be safely removed
- History or diagnosis of bipolar or chronic psychotic disorder (e.g., schizophrenia, schizoaffective disorder).
