纳入标准:

1. 有正常的沟通交流能力; 2. 年龄范围:55-80岁之间,性别不限; 3. 经临床标准评估确诊为认知障碍。 所有受试者均接受系统的临床标准评估,包括认知功能筛查、潜在病因排查及严重程度分级。评估通过以下 5 个维度完成:病史采集、体格检查、神经心理评估、实验室检查和影像学检查。 (1) 病史采集 伴有认知功能减退,复杂的工具性日常能力轻微损害,非认知性神经精神症状,如淡漠、抑郁、焦虑; (2) 体格检查 伴有意识、高级皮质功能检查(远近记忆力、理解力、定向力、计算力和判断力)、脑神经、运动系统(肌容积、肌张力、肌力、不自主运动、共济运动、步态)、感觉系统(浅感觉、深感觉、复合感觉)、反射(浅反射、深反射、病理反射)和脑膜刺激征功能异常; (3) 神经心理学评估 根据 Addenbrooke 评估量表(ACE-Ⅲ量表)[13],不同教育水平的认知障碍诊断评分不同:1-9 年教育水平,评分< 72 分;10-15 年教育水平,评分< 78 分;> 16 年教育水平,评分< 80 分;根据临床痴呆评定量表(Clinical Dementia Rating, CDR)对认知障碍的严重程度进行分级,CDR = 0.5 为可以痴呆/轻度认知障碍,CDR = 1.0 为轻度痴呆,CDR = 2.0 为中度痴呆,CDR = 3.0 为重度痴呆; (4) 实验室检查 发现认知障碍病理相关生物标志物; (5) 影像学检查 伴有特征性的代谢降低模式和超越正常年龄老化的、具有疾病特征模式的脑萎缩。

Inclusion criteria

1. Normal communication ability; 2. Age range: 55-80 years old, gender; 3. Diagnosed with cognitive impairment according to clinical standard assessment. All participants underwent systematic clinical standard assessment, including cognitive function screening, potential etiology exclusion, and severity grading. The assessment was completed through the following 5 dimensions: medical history collection, physical examination, neuropsychological assessment, laboratory tests, and imaging examination. (1) Medical history collection Presence of cognitive decline, mild impairment in complex instrumental activities of daily living, and non-cognitive neuropsychiatric symptoms, such as apathy, depression, and anxiety; (2) Physical examination Abnormalities in consciousness, higher cortical function tests (remote and recent memory, comprehension, orientation, calculation, and judgment), cranial nerves, motor system (muscle bulk, muscle tone, muscle strength, involuntary movements, coordination, gait), sensory system (superficial sensation, deep sensation, composite sensation), reflexes (superficial reflexes, deep reflexes, pathological reflexes), and meningeal irritation signs; (3) Neuropsychological assessment According to the Addenbrooke's Cognitive Examination III (ACE-III) [13], cognitive impairment diagnostic cut-off scores vary by education level: 1-9 years of education, score < 72; 10-15 years of education, score < 78; >16 years of education, score < 80; Severity of cognitive impairment is graded using the Clinical Dementia Rating (CDR) scale: CDR = 0.5 indicates questionable dementia/mild cognitive impairment, CDR = 1.0 indicates mild dementia, CDR = 2.0 indicates moderate dementia, CDR = 3.0 indicates severe dementia; (4) Laboratory tests Detection of biomarkers related to cognitive impairment pathology; (5) Imaging examination Presence of characteristic patterns of hypometabolism and brain atrophy with disease-specific patterns that exceed normal age-related changes.

排除标准:

1. 存在精神和心理障碍,不能签署知情同意书或无法配合完成测试者; 2. 脑血管病、肿瘤、感染或自身免疫性疾病的患者; 3. 皮肤问题:在神经调控设备接触区域有皮肤感染、伤口或其他皮肤问题; 4. 心理依赖:有药物滥用或酒精依赖的历史。

Exclusion criteria:

1. Individuals with mental or psychological disorders who cannot sign the informed consent form or are unable to cooperate with the test; 2. Patients with cerebrovascular disease, tumours, infections, or autoimmune diseases; 3. Skin issues: skin infections, wounds, or other skin problems in areas where neurostimulation devices are applied; 4. Psychological dependence: history of substance abuse or alcohol dependence.
