研究目的:

旨在全面评估AD源性MCI、AD患者与认知健康人群相比眼底结构(如各层视网膜厚度、黄斑区各层视网膜血管密度、脉络膜血流密度等)和泪液中特定生物标志物(如pTau、Aβ、NfL等)的变化差异,探索上述指标联合是否能够帮助临床医生更早、更准确地无创诊断AD及其早期阶段  

Objectives of Study:

The aim is to comprehensively evaluate differences in fundus structure (such as retinal thickness, retinal vascular density in the macular region, and choroidal blood flow density) and specific biomarkers in tears (such as pTau, Aβ, and NfL) between patients with AD-related MCI and AD, and healthy individuals, and to investigate whether the combination of these markers can assist clinicians in diagnosing AD and its early stages earlier and more accurately in a non-invasive manner.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.可用的脑脊液、PET、CT或MRI数据,用于评估神经退行性病变的存在与否(最好在纳入本研究后1年内获取);
2.OCT/OCTA图像质量评分(0~10)>=7;
3.无可能影响泪液生化参数的眼部疾病(包括眼部感染、眼部炎症、28天内接受过眼部手术或其他急性眼部疾病);
4.已获取书面知情同意并存档;
5.年龄>50岁;
6.无迹象表明无法进行随访(最长12个月);
7.MCI/AD的额外纳入标准:痴呆症的临床诊断将依据《精神障碍诊断与统计手册-5》(DSM-5)中关于重大神经认知障碍的标准进行,同时采用美国国家老龄研究所-阿尔茨海默病协会(NIA-AA)的临床诊断标准,且能够做出知情同意(简易精神状态检查(Mini-mental Status Exam, MMSE)评分>17/30分),其中MCI的诊断要求患者认知功能受损但具备日常生活功能,因此无法被诊断为AD;
8.认知健康对照者的额外纳入标准:基线MMSE评分26–30分,无认知功能问题或治疗史,且当前或过去未因认知问题寻求帮助。

Inclusion criteria

1. Available cerebrospinal fluid, PET, CT or MRI data to assess the presence or absence of neurodegenerative disease (preferably obtained within one year of enrolment in this study);
2. OCT/OCTA image quality score (0–10) >= 7;
3. No ocular conditions likely to affect tear biochemistry parameters (including ocular infections, ocular inflammation, ocular surgery within the previous 28 days, or other acute ocular conditions);
4. Written informed consent obtained and on file;
5. Age > 50 years;
6. No indications of inability to undergo follow-up (up to 12 months);
7. Additional inclusion criteria for MCI/AD: The clinical diagnosis of dementia will be based on the criteria for Major Neurocognitive Disorder in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), in conjunction with the National Institute on Ageing–Alzheimer’s Association (NIA-AA) clinical diagnostic criteria, and the patient must be capable of providing informed consent (Mini-Mental State Examination (MMSE) score > 17/30). The diagnosis of MCI requires that patients exhibit impaired cognitive function but retain the ability to perform activities of daily living, consequently, they cannot be diagnosed with AD;
8. Additional inclusion criteria for cognitively healthy controls: baseline MMSE score of 26–30, no history of cognitive impairment or treatment, and no current or past history of seeking help for cognitive problems.

排除标准:

1.患有其他神经系统疾病(如亨廷顿舞蹈病、多发性硬化症);
2.患有糖尿病、肾病或其他影响脉络膜循环的全身性疾病;
3.长期使用激素;
4.患有可能影响泪液成分的眼部疾病(如眼部感染、炎症或过去28天内进行过眼部手术);
5.危及生命的危重症患者。

Exclusion criteria:

1. Patients with other neurological conditions (such as Huntington’s disease or multiple sclerosis);
2. Patients with diabetes, kidney disease or other systemic conditions affecting choroidal circulation;
3. Patients on long-term steroid therapy;
4. Patients with eye conditions that may affect tear composition (such as eye infections, inflammation or eye surgery within the past 28 days);
5. Patients in a life-threatening critical condition.

所有数据均来源于受试者的现场观察记录,包括:一般资料、诊断信息、病史、眼底影像学参数、泪液生物标志物检测结果、随访记录等。研究采用 EDC 进行数据录入。 所有观察结果需先记录在原始观察记录(电子病历、影像报告、实验室报告、CRF等)中,再由受试者专属研究人员录入EDC。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

All data were derived from on-site observations of the subjects, including: demographic information, diagnostic details, medical history, fundus imaging parameters, tear fluid biomarker test results, and follow-up records. Data entry was performed using an Electronic Data Capture (EDC) system. All observations must first be recorded in the original observation records (electronic medical records, imaging reports, laboratory reports, Case Report Forms, etc.), before being entered into the EDC by the subject’s designated investigator.
