t-pemf headband stimulation for patients with moderate to servere depression

Conditions: Moderate Depression; Severe Depressive Episode Without Psychotic Symptoms; Recurrent Depressive Disorder, Current Episode Moderate; Recurrent Depressive Disorder, Current Episode Severe Without Psychotic Symptoms

Summary: an 8-week, two-armed, randomized-controlled trial that examines the antidepressant effect of treatment with transcranial pulsed electromagnetic fields (t-pemf) in patients diagnosed with moderate to severe depressionusing using a new device, the moodheadband (mhb). the participants will use an active or placebo mhb for 30 minutes daily for 8 weeks. additionally, the following research questions will be answered: 1. if the time to respond to treatment differ between the active treatment and sham group 2. if there is a positive effect on the patients' emotional and non-emotional cognition after 8 weeks of active treatment compared to the sham group and if possible early changes in the emotional cognition can predict the treatment response after 8 weeks of treatment. 3. if the t-pemf treatment provides improvement in restorative sleep after 8 weeks of treatment

the purpose of this study is to clarify whether daily treatment over eight weeks with weak pulsating electromagnetic fields (t-pemf) can achieve a safe effect on depression compared to the same treatment with a placebo t-pemf. the study will furthermore explore possible effects on cognition and the hypothesized sleep-ameliorating effect of t-pemf. previous danish studies have shown a significant antidepressant effect of other t-pemf devices in the treatment of patients with depression. the study is designed as a blinded, randomized study where active treatment is compared with inactive (placebo) treatment. at the same time, possible side effects in the use of the headband (moodheadband, mhb) are investigated. the project was initiated june 2024. patients consecutively referred are asked after an initial interview whether they wish to participate in the study. if they give informed consent to this, they will be randomized to active or placebo treatment. the treatment itself takes place at home, 30 minutes once a day, for 8 weeks. "treatment as usual" takes place in parallel to the study treatment, and consists of psychotherapy in a group or individually and antidepressive medications. follow-ups will be conducted weekly either as visits at the clinic, via videocall or as telephone calls. the participants will receive weekly surveys they are encouraged to fill out prior to the weekly follow-ups. the severity of the depression, including its symptomatology will be examined weekly during the study, the cognitive test-battery is applied at baseline, week 1 and at the final visit, the patients sleep-pattern and possible disturbances are examined via the weekly surverys. no significant side effects have been registered when using the same type of magnetic field treatment in the previous danish studies. it has also been shown that it is possible to carry out the treatment at home without significant problems.
