- NCT06371352
- Lead Sponsor
- Jakub Antczak
- Brief Summary
Intermittent and continuous theta-burst stimulation (iTBS and cTBS respectively) are the newer modalities of transcranial magnetic stimulation with documented efficacy in treatment of depressed mood but with conflicting results regarding their efficacy in treatment of other symptoms of depression such as insomnia, daytime sleepiness and fatigue. This study will investigate the efficacy of iTBS over the left dorsolateral prefrontal cortex (DLPFC) and cTBS over the right DLPFC, compared to sham stimulation, in treatment of insomnia, daytime sleepiness and fatigue in depression.
- Detailed Description
Intermittent and continuous theta-burst stimulation (iTBS and cTBS respectively) are the newer modalities of conventional repetitive transcranial magnetic stimulation (rTMS) with documented noninferiority in improving mood in depressive disorders. The effect of both modalities on other significant depression symptoms has not been studied. In this feasibility study investigators aim primarily to assess the safety and therapeutic potential of iTBS over the left dorsolateral prefrontal cortex (lDLPFC) and cTBS over the right dorsolateral prefrontal cortex (rDLPFC) on sleep quality, sleep propensity, fatigue, and daytime sleepiness in patients with major and bipolar depression.

Group Intervention Description iTBS over the left DLPFC iTBS Active iTBS with intensity of 120% of the resting motor threshold recorded from the right first dorsal interosseus will be administered over the left DLPFC. Therapy will include 90 sessions (three sessions in each of 20 consecutive working days - four weeks in total). In every session 900 magnetic pulses will be elicited. Sham stimulation Sham Active iTBS or cTBS will be administered over the left or right DLPFC respectively with sham coil. Therapy will include 90 sessions (three sessions in each of 20 consecutive working days - four weeks in total). In every session 900 or 1200 magnetic pulses will be elicited. cTBS over the right DLPFC cTBS Active cTBS with intensity of 120% of the resting motor threshold recorded from the left first dorsal interosseus will be administered over the right DLPFC. Therapy will include 90 sessions (three sessions in each of 20 consecutive working days - four weeks in total). In every session 1200 magnetic pulses will be elicited.
- Primary Outcome Measures
Name Time Method Pittsburgh Sleep Quality Index Before intervention - four weeks after finishing intervention. Pittsburgh Sleep Quality Index is a questionnaire to identify sleep disturbances. It consists of a combination of Likert-type and open-ended questions, which are later converted to scaled scores. Scores for each question range from 0 to 3, with higher scores indicating greater sleep disturbances. The minimum value of the total score is 0 and the maximum is 21 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention.
Beck Depression Inventory 2 Before intervention - four weeks after finishing intervention. Inventory consisting of 21 items measuring cognitive, affective, somatic, and vegetative symptoms of depression. Each item is scored from 0 to 3, with a higher score denoting more severe depression. Items are related to the criteria from the Diagnostic and Statistical Manual of Mental Disorders-IV. The minimum value of the total score is 0 and the maximum is 63 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention.
- Secondary Outcome Measures
Name Time Method Sleep propensity non-rapid eye movement 2 sleep stage Through study completion, an average of 1 year A 23-channel electroencephalography (EEG), 2-channel electrooculogram (EOG) and a chin electromyogram (EMG) recorded through 45 minutes in lying position with eyes closed. The recordings will then be divided into 30 second epochs. Each epoch will be assigned to particular sleep stage or wake, according to standards of sleep staging issued by the American Academy of Sleep Medicine \[Silber et al. 2007\]. The difference in the latency of non-rapid eye movement 2 sleep stage (the time from light off to the first epoch of the non-rapid eye movement 2 sleep stage) before and after intervention will be assessed.
Brief Psychiatric Rating Scale Before intervention - four weeks after finishing intervention. An 18-item scale assessing negative symptoms, such as emotional withdrawal (e.g. withdrawal from relations), motor slowness and blunted affect. Each item is rated from 1 to 7 with 7-point Likert scaling, where 7 means the most severe disturbance. The minimum value of the total score is 18 and the maximum is 126 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention.
Epworth Sleepiness Scale Before intervention - four weeks after finishing intervention. An eight-item scale. Each item refers to a situation such as driving a car or sitting quietly. The subject is asked to assess the chance of dosing in each situation, ranging from 0 (no chance) to 3 (dosing very likely). The minimum value of the total score is 0 and the maximum is 24 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention.
Sleep propensity non-rapid eye movement 1 sleep stage Through study completion, an average of 1 year A 23-channel electroencephalography (EEG), 2-channel electrooculogram (EOG) and a chin electromyogram (EMG) recorded through 45 minutes in lying position with eyes closed. The recordings will then be divided into 30 second epochs. Each epoch will be assigned to particular sleep stage or wake, according to standards of sleep staging issued by the American Academy of Sleep Medicine \[Silber et al. 2007\]. The difference in the latency of non-rapid eye movement 1 sleep stage (the time from light off to the first epoch of the non-rapid eye movement 1 sleep stage) before and after intervention will be assessed.
Quality of Life in Depression Scale Before intervention - four weeks after finishing intervention. A 34-item, self-reported scale to assess the impact of depression on the quality of life. The scale is scored binomially with higher scores indicating a lower quality of life. The minimum value of the total score is 0 and the maximum is 34 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention.
Fatigue Assessment Scale Before intervention - four weeks after finishing intervention. A 10-item scale to assess the severity of fatigue. Each item is an expression describing the fatigue, such as: "I am bored by fatigue" or "Mentally I feel exhausted". Each item is answered using a Likert-type scale ranging from 1 (never) to 5 (always). The minimum value of the total score is 10 and the maximum is 50 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention.
