项目介绍
经颅直流电刺激（tDCS）在一般公立医院参考费用约¥140-400，三甲医院参考费用约¥200-500，常用于相关诊断评估与就医安排，费用随医院及地区有所差异。
主要用途
Primary clinical and research applications include: adjunctive treatment for major depressive disorder (especially treatment-resistant depression), cognitive rehabilitation in stroke and traumatic brain injury, modulation of motor cortex excitability in Parkinson’s disease and chronic pain syndromes, enhancement of working memory and attention in healthy aging and ADHD, and experimental use in addiction, anxiety, and schizophrenia — always as part of multimodal therapy under professional supervision.
正常值范围
tDCS is not a diagnostic laboratory test with quantitative 'values' or reference ranges; it is a non-invasive neuromodulation technique. Parameters are set by the clinician and include: current intensity (typically 1–2 mA), session duration (20–30 minutes), electrode size (25–35 cm²), and electrode placement (e.g., F3/F4, C3/C4 per 10–20 EEG system). No biological 'normal range' exists for tDCS output — safety thresholds are defined by international guidelines (e.g., ≤2 mA, ≤30 min, current density ≤0.08 mA/cm²).
偏低可能原因
Low perceived or measured stimulation effect may result from: 1) Subthreshold current intensity (<1 mA), 2) Inadequate electrode contact or high skin impedance, 3) Incorrect electrode placement (e.g., misaligned montages), 4) Insufficient session duration (<15 min), 5) Individual neuroanatomical variability (e.g., skull thickness, cortical atrophy).
偏高可能原因
Excessive or unintended stimulation effects may arise from: 1) Current intensity exceeding 2 mA (off-label/unapproved), 2) Prolonged session duration (>30 min), 3) Small electrode size leading to elevated current density (>0.08 mA/cm²), 4) Use of conductive gels/solutions with uncontrolled ion concentration, 5) Concurrent use with other neuromodulatory agents (e.g., certain medications lowering seizure threshold).
