Inclusion criteria
Inclusion criteria: 1. Age from 55 to 80 years old, male or female. 2. Years of education >= 8 years (junior high school or above). 3. The visual acuity or corrected visual acuity was normal, and the hearing of both ears was normal. They are all right handed. 4. The informed consent was signed, and the peripheral blood and cerebrospinal fluid were collected. Multimodal MRI scanning was also completed for each participant. The inclusion criteria of SCD were as follows: (1) memory loss: memory loss was assessed by the simplified Chinese version of memory questionnaire, which could be completed by patients or their family members. The score of the questionnaire >=3 and the course of disease =6 months were considered as memory loss. (2) Normal objective cognitive function tests: Mini-mental state examination (MMSE) >=24, Montreal cognitive assessment (MoCA) >=26, Clinical dementia rating (CDR) =0; (3) Activity of daily living (ADL) was normal. MCI inclusion criteria: according to the core clinical diagnostic criteria of MCI caused by AD in NIA-AA 2011: (1) Patients had a complaint of memory impairment and the course of disease was >=6 months; (2) Impaired objective episodic memory cognitive domain (-20 min delayed recall of auditory verbal learning test lower than the corresponding norm); (3) The general cognitive function was normal and did not meet the diagnostic criteria of clinical Dementia: MMSE>=24, Mattis Dementia Rating Scale (MDRS) >120, CDR=0.5; (4) Independent in daily life: ADL26; (2) Global cognitive decline: MMSE=26, MDRS>120, normal ADL, Hamilton Depression Scale (HAMD) <=7, Hachinski Ischemia Scale (HIS) <=4; (4) The multidimensional neu
