The study aims to investigate the efficacy and safety of intermittent theta burst stimulation (iTBS) guided by the personalized Brain Functional Sector (pBFS) technique in the treatment of patients with chronic post-stroke cognitive impairment.
Cognitive impairment, characterized by memory loss, attention and executive functional impairment, is a common complication following stroke. Intermittent Theta Burst Stimulation (iTBS) is a non-invasive neuromodulation technique that applies pulsed magnetic fields to the cerebral cortex, inducing changes in local or distal neural activity and promoting cognitive function. By employing the personalized Brain Functional Segmentation (pBFS) technique, individualized brain functional networks can be precisely identified based on resting-state functional MRI scans. Within the executive function network, a specific region of the dorsolateral prefrontal cortex (DLPFC) will be selected as the intervention target.
Participants will be randomly assigned to two groups at 1:1 ratio: the active group and the sham group. The stimulation will be administered using a figure-of-8 coil with the assist of a real-time neuronavigation system. Two sessions of 1800 pulses will be applied, totaling 3600 pulses per day, with at least 50-minute interval period between sessions for both groups. The sham stimulation will be administered using a sham coil that mimics the sound and appearance of the active stimulation coil but does not deliver actual stimulation. The intervention will be administered on workdays, over a period of 3 weeks, totaling 15 treatment days.

| change in the Montreal cognitive assessment (MoCA) | The Montreal Cognitive Assessment (MoCA) is a rapid screening tool used to assess mild cognitive impairment (MCI). It evaluates cognitive function across seven domains, including visuo-spatial and executive function, naming, memory, attention, language, abstraction, and delayed recall. The total score on the MoCA is 30, with higher scores indicating better cognitive function. | baseline, end of the 3-week therapy |

| sham iTBS | Device | Participants in this group will receive two sessions of 1800-pulse sham stimulation per day, with an intersession interval of at least 50 minutes. The stimulation will be comprehensively mimic the active condition, and also administered on workdays over a period of 3 weeks, totaling 15 days. |

| baseline, 3 months post-treatment |
| change in the Mini-mental state examination(MMSE) | The Mini-Mental State Examination (MMSE) is a widely employed neuropsychological test for evaluating cognitive decline. It comprises 11 items that assess five key domains: orientation, memory, attention and calculation, recall, and language abilities. The total score on the MMSE is 30, with higher scores indicating better cognitive function. | baseline, end of the 3-week therapy, 3 months post-treatment |
| change in the Rivermead Behavioural Memory Test (RBMT ) | The Rivermead Behavioral Memory Test (RBMT) is a tool utilized to evaluate individuals' daily memory capabilities, encompassing immediate memory, delayed recall, visual memory, and anticipatory memory. A total score of 24 is allocated, with lower scores indicating decreased memory performance. | baseline, end of the 3-week therapy |
| change in the Stroop color word test (SCWT) | The Stroop Color Word Test (SCWT) is employed to evaluate selective attention, cognitive flexibility, and processing speed. The test comprises three components. Higher scores and shorter completion times on the SCWT indicate better performance and outcomes. | baseline, end of the 3-week therapy |
| change in the Symbol Digit Modalities Test (SDMT) | The Symbol Digit Modalities Test (SDMT) is a neuropsychological assessment that measures attention, processing speed, and cognitive flexibility. During the SDMT, participants are tasked with converting symbols into their corresponding numbers within a given time limit, using a symbol-digit control chart as reference. Higher completion rates on the SDMT indicate better performance and outcomes in the test. | baseline, end of the 3-week therapy |
