Kokeellinen: Focused Ultrasound Neuromodulation
Focused Ultrasound Neuromodulation: Participants will receive two sessions of Magnetic Resonance-guided focused ultrasound neuromodulation targeting regions within the cortical-striatal-thalamic circuit (CSTC) implicated in treatment-resistant depression.
Treatments will be spaced four weeks apart.
All participants will receive the same intervention and will be followed for 4 weeks post-treatment to evaluate clinical outcomes, adverse events, and depression symptoms.
|
Osallistujat saavat kaksi istuntoa magneettikuvausohjatusta keskittyneestä ultraääni-neuromodulaatiosta, joka on etäisyydellä neljän viikon välein seuraavan sukupolven kupolikypärääkkeen avulla.
Käsittelyt kohdistuvat CSTC -piirin alueille, jotka on tunnistettu edistyneillä MRI -skannauksilla.
Jokainen istunto sisältää esikäsittelyn arvioinnit, syvien aivojen rakenteiden tarkkoja ääniä, reaaliaikaisen turvallisuuden seurannan ja hoidon jälkeisen kuvantamisen.

Change in Obsessive-Compulsive Symptom Severity Measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS)
Aikaikkuna: Assessments will be conducted at baseline; 24 hours after each treatment; at 1 and 2 weeks after each treatment; and 4 weeks after the second treatment.
|
Evaluate the effectiveness of FUS Neuromodulation in reducing obsessive-compulsive symptom severity using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS).
The Y-BOCS is a clinician-administered scale assessing the severity of obsessive-compulsive symptoms.
Total scores range from 0 to 40, with higher scores indicating greater symptom severity (0-7 subclinical, 8-15 mild, 16-23 moderate, 24-31 severe, and 32-40 extreme).
|
Assessments will be conducted at baseline; 24 hours after each treatment; at 1 and 2 weeks after each treatment; and 4 weeks after the second treatment.

Change in Quality of Life as Measured by the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q)
Aikaikkuna: Assessments will be conducted at baseline; 24 hours after each treatment; at 1 and 2 weeks after each treatment; and 4 weeks after the second treatment.
|
Quality of life will be assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q).
The Q-LES-Q is a self-report measure assessing quality of life across multiple domains.
Total scores are typically transformed into a percentage of the maximum possible score, with higher percentages indicating greater life satisfaction and functioning.
Change from baseline will be evaluated at each assessment time point.
