Multimodal brain imaging neurotransmitter marker study of TD: a review of TCM effect mechanisms and precise diagnosis and treatment combining traditional Chinese and western medicine.
Review in American journal of translational research, 2026. 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
objectiveTo systematically summarize findings from multimodal brain imaging and neurotransmitter marker studies in Tic disorders (TD), to explore potential neurobiological mechanisms underlying Traditional Chinese Medicine (TCM) interventions, and to propose a precision diagnosis framework integrating TCM and Western medicine.
methodsThis is a critical narrative review. A systematic literature search was conducted in PubMed, CNKI, and Wanfang databases up to October 2025 using keywords including "TD", "Tourette syndrome", "multimodal imaging", "neurotransmitter", and "TCM", ensuring comprehensive coverage. However, data synthesis followed a narrative, hypothesis-generating approach rather than a formal systematic review or meta-analysis framework.
resultsStructural MRI reveals basal ganglia volume reductions and cortical thickness abnormalities; functional MRI shows disrupted cortico-striato-thalamo-cortical (CSTC) connectivity and compensatory activation; DTI demonstrates white matter microstructural alterations; PET/SPECT identifies dopaminergic hyperactivity and serotonergic dysfunction; MRS indicates GABA-glutamate imbalance. TCM interventions (herbal formulas, acupuncture) modulate these imaging phenotypes with good safety profiles. However, most human imaging evidence for TCM remains correlational and preliminary, with animal models providing mechanistic hypotheses that require cautious translation.
conclusionsMultimodal biomarkers enable objective subtyping and treatment monitoring. Limitations include small sample sizes, cross-sectional designs, comorbidity confounding, and TCM-specific challenges (herbal quality control, blinding difficulties). Future research should prioritize large-scale longitudinal cohorts, standardized TCM randomized controlled trials, and low-cost biomarker translation for primary care implementation.
