Selective Attention Deficits and Neuromodulation in Major Depressive Disorder: Using EEG and MRI-guided iTBS Study

Обзор

Multimodal study (Behavior, TMS, EEG) combining a sham-controlled intermittent theta burst stimulation (iTBS) intervention with an additional-singleton task and EEG to evaluate whether left dorsolateral prefrontal cortex (DLPFC) stimulation enhances cognitive control and modulates maladaptive attention processes in MDD and whether the effects are influenced by neuronavigated versus manual (Beam F3 method) localization of the stimulation site.

Подробное описание

Major Depressive Disorder (MDD) is associated with impaired selective attention and disrupted top-down control, yet the underlying neurophysiological mechanisms remain poorly understood. The present double-blind, sham-controlled trial will test whether iTBS over the left DLPFC, an FDA-approved rTMS site, can restore top-down distractor suppression in MDD (active-iTBS: n = 30; sham-iTBS: n = 30). Neuronavigated iTBS will be delivered across sessions, and effects will be assessed on the behavioral level (additional singleton paradigm) and the neurophysiological level (using concomitant EEG). Key aim of the project is to compare neuronavigated (active-iTBS) versus manual (Beam F3 method, sham-iTBS group) localization of the stimulation site.

Вмешательства

  • Устройство intermittent theta burst stimulation (iTBS) intervention
    iTBS protocol: Intervention with an 80-120% resting threshold was used. In the active group, the left dlPFC was selected as the stimulation site and a stimulation protocol with iTBS parameters was given. This was a neuro-modulation protocol of excitatory sequences, with theta burst stimulation at 50 Hz, repeated at 5 Hz, stimulation for 2 s with an interval of 8 s, for a total of 1,800 pulses, with a treatment time of about 20 min/session, two sessions per day, with a15-30 min rest between sessi

Первичные конечные точки

Вторичные конечные точки (3)
  • Intervention-related ERPs changes in the additional singleton task after 2 weeks of active/sham iTBS treatment. [Срок оценки: 30-60 minutes before the first iTBS treatment and 30-60 minutes after last iTBS treatment.]
  • Intervention-related brain connectivity after 2 weeks of active/sham iTBS treatment. [Срок оценки: 30-60 minutes before the first iTBS treatment and 30-60 minutes after last iTBS treatment.]
  • Intervention-related behavior changes in the additional singleton task after 2 weeks of active/sham iTBS treatment. [Срок оценки: 30-60 minutes before the first iTBS treatment and 30-60 minutes after the last iTBS treatment.]
