Study summary

Obsessive Compulsive Disorder (OCD) is a psychiatric disorder in which involuntary thoughts and irresistible behaviors are seen and its prevalence affects 2%-3% of the general population. Deep TMS is a treatment method that provides stimulation of lower parts of the brain and larger brain volume, and in addition to drug treatment and psychotherapy approaches, magnetic stimulation of localized brain regions and disease symptoms are addressed. The presence of the medial prefrontal cortex and anterior cingulate cortex in the dysfunction on the specified cycle seen in OCD patients indicates that the stimulation of these regions is necessary for a meaningful result in the treatment of deep TMS; studies show that the effect of the deep TMS method emerges as a result of the stimulation of these regions. 30 patients with OCD will included into the study and dividen into 3 groups (DTMS (n=10), DTMS + Paroxetine (n=10), Control(n=10)). Patients will evaluated in terms of depression, quality of life, and EEG before and after the intervention.

Study arms

  • Active comparator
    Deep Transcranial Magnetic Stimulation

    The treatment will be carried out for 6 weeks, 5 days a week, in total 30 sessions; 20 hz using Brainsway H-7 helmet. It will be applied to the mPFC and ACC simultaneously with a total of 2000 beats at a frequency of 50 beats in each string.

    Device: Deep Transcranial Magnetic Stimulation

  • Experimental
    Deep Transcranial Magnetic Stimulation and Paroxetine

    The treatment will be carried out for 6 weeks, 5 days a week, in total 30 sessions; 20 hz using Brainsway H-7 helmet. It will be applied to the mPFC and ACC simultaneously with a total of 2000 beats at a frequency of 50 beats in each string. In addtion to DTMMS, paroxetine will applied.

    Device: Deep Transcranial Magnetic Stimulation · Drug: Paroxetine

  • Active comparator
    Paroxetine

    Paroxetine is a type of antidepressant known as an SSRI (selective serotonin reuptake inhibitor). It's often used to treat depression in OCD.

    Drug: Paroxetine

Interventions

  • DeviceDeep Transcranial Magnetic Stimulation

    Deep TMS, unlike traditional TMS, is a treatment method that provides stimulation of lower parts of the brain and larger brain volume, in addition to drug treatment and psychotherapy approaches, in addition to localized brain regions magnetic stimulation is a treatment method where disease symptoms are addressed.

  • Paroxetine is a type of antidepressant known as an SSRI (selective serotonin reuptake inhibitor). It's often used to treat depression.

What researchers measure

Primary outcomes

  1. Electroencephalography

    It is an electrophysiological neuroimaging method frequently used in neuroscience and clinic, in which the activity between neural circuits can be measured and observed non-invasively in the form of electrical waves.

    Time frame: 6 weeks after baseline

Secondary outcomes

  1. Beck Depression Scale

    It is the scale used for evaluated the level of depression. Higher score means worse result.

    Time frame: 6 weeks after baseline

  2. World Health Organization Quality of Life Scale Short Form

    It is the scale used for evaluated the level of quality of life. It contains a total of 26 questions. Higher score means better result.

    Time frame: 6 weeks after baseline

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2020 to primary completion in Oct 2021, 17 months.

Of 230 non-industry interventional studies with no phase under Obsessive-Compulsive Disorder, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 68. This study's 17 months is below that.

Counting every sponsor, half of 232 studies reached it within 43 months; a quarter within 22 and three quarters within 65.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 12, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
