Advances in transcranial magnetic stimulation for psychological symptom management in Parkinson's disease.
Review in World journal of psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Parkinson's disease patients, in addition to typical motor symptoms, often experience various psychological symptoms, including depression, anxiety, cognitive impairment, impulse control disorders, and psychotic symptoms. These symptoms severely affect patients' quality of life and may even cause a greater disease burden than motor symptoms. This review focuses on the application progress of transcranial magnetic stimulation (TMS) as a non-invasive neuromodulation technique in the treatment of psychological symptoms in Parkinson's disease. Studies have shown that repetitive TMS (rTMS) has significant improvement effects on Parkinson's disease-related depressive symptoms, with mechanisms possibly related to the regulation of the prefrontal-striatal dopamine pathway and the promotion of neuroplasticity. For anxiety symptoms, continuous theta burst stimulation has shown potential in indirect regulation of the amygdala and hippocampal regions. For cognitive impairment, high-frequency rTMS applied to the dorsolateral prefrontal cortex can improve executive function deficits, while bilateral coordinated stimulation protocols help enhance attention and memory functions. For impulse control disorders in Parkinson's disease patients, inhibitory stimulation applied to the orbitofrontal cortex can alleviate pathological gambling and compulsive behaviors. In terms of sleep disorders, TMS has also shown potential efficacy in regulating circadian rhythms and improving rapid eye movement sleep behavior disorder. However, current research still has limitations such as small sample sizes, non-standardized stimulation protocols, and insufficient evaluation of long-term efficacy. Future research directions should focus on optimizing stimulation parameters, exploring individualized treatment protocols, integrating multimodal imaging assessments, and conducting large-sample randomized controlled trials to clarify the clinical application value of TMS in the rehabilitation of psychological symptoms in Parkinson's disease, providing new approaches for the comprehensive management of this common neurodegenerative disease.
