Article Abstract
Background: Intermittent theta burst stimulation (iTBS) is an accepted and approved brain stimulation technique to treat patients with treatment-resistant depression.
Aim: Using neuroimaging, this open-label study aimed to predict the response by observing glucose metabolism with the help of 18-FDG PET scan.
Methods: A total of 25 treatment-resistant depression patients received 15 sessions of iTBS on the left dorsolateral prefrontal cortex. Two FDG-PET scans were done for all the patients. Fifty-six percent of patients responded to treatment with iTBS.
Results: We found that there was hypometabolism in left and right prefrontal lateral regions, left and right inferior parietal regions, and left prefrontal medial regions at baseline but no statistically significant difference in the metabolism between responders and nonresponders.
Conclusion: We did not find any statistically significant difference in the metabolism between responders and nonresponders in any brain regions at T0 as well as T1. Further large-scale studies are required.

Electroencephalography (EEG) is a comparatively inexpensive and non-invasive recording technique of neural activity, making it a valuable tool for biomarker discovery in transcranial magnetic stimulation (TMS). This systematic review aimed to examine mechanistic and predictive biomarkers, identified through TMS-EEG or resting-state EEG, of treatment response to TMS in psychiatric and neurocognitive disorders. Nineteen articles were obtained via Embase, APA PsycInfo, MEDLINE, and manual search; conditions included, unipolar depression (k = 13), Alzheimer's disease (k = 3), bipolar depression (k = 2), and schizophrenia (k = 2).

Background: Theta Burst Stimulation (TBS) is a form of non-invasive brain stimulation that can induce neuroplastic changes in the underlying intracortical areas. It has significant potential in clinical and research settings for modulating cognitive and motor performance. Little is known about how TBS affects oxygenations levels within and across brain hemispheres during stimulation of the Dorsolateral Prefrontal Cortex (DLPFC).

Objective: This study evaluates the efficacy and underlying mechanisms of intermittent theta-burst stimulation (iTBS) in improving cognitive function and quality of life in post-stroke patients.
Methods: A total of 80 subacute stroke patients with cognitive deficits were randomly assigned to a control group ( = 40) receiving conventional treatment plus sham stimulation and an experimental group ( = 40) receiving conventional treatment plus iTBS over the left dorsolateral prefrontal cortex for 4 weeks.
Results: Baseline characteristics were comparable between groups.
