Eligibility
Inclusion criteria
Inclusion criteria: 1 Mild Alzheimer's disease (AD): (1) Early and significant episodic memory impairments reported by the patient or informant. (2) Insidious onset, gradual progression, with a duration of =6 months. (3) Objective evidence of overall cognitive dysfunction and/or episodic memory impairment assessed using AD-specific cognitive scales. (4) Impairment in activities of daily living (ADL) due to cognitive dysfunction. (5) CDR score of 0.5 or 1. 2 Mild Cognitive Impairment (MCI): (1) Self-reported memory decline by the individual and/or informant. (2) Objective evidence of impairment on neuropsychological tests, particularly in memory (delayed recall = -1.5 SD). (3) Overall cognitive function is normal, with CDR score of 0 or 0.5. (4) Suspicious or mild impairments in instrumental activities of daily living and behavior. (5) Non-dementia condition. 3 Subjective Memory Complaints (SMC): (1) Self-reported memory decline by the individual and/or informant. (2) No objective evidence of impairment on neuropsychological tests (all relevant tests within the normal range). (3) Normal overall cognitive function, with CDR score of 0. 4Normal Cognitive Aging: (1) No self-reported memory decline by the individual or family members. (2) No objective evidence of impairment on neuropsychological tests (all relevant tests within the normal range). (3) Normal overall cognitive function, with CDR score of 0.
Exclusion criteria
Exclusion criteria: Exclusion criteria: 1. Acute onset with a duration of less than 6 months. 2.

Presence of non-degenerative cognitive impairment-related lesions or changes observed in imaging studies (e.g., MRI/CT). 4. Existence of secondary factors that could contribute to cognitive impairment, including but not limited to, traumatic brain injury, cerebrovascular disease, infections, metabolic disorders, endocrine disorders, and psychiatric/emotional factors. 5. Presence of contraindications for magnetic resonance imaging (MRI) and transcranial magnetic stimulation.
