Presence of underlying neurological diseases that may impair cognitive function, including but not limited to dementia syndrome, Parkinson's disease, epilepsy, and cerebrovascular disease.\n* Presence of severe or unstable organic diseases such as cancer, hydrocephalus, history of central nervous system tumors, or acute brain injury\u002Finfection.\n* Diagnosis of severe mental illness such as major depressive disorder, schizophrenia, schizoaffective disorder, or bipolar disorder.\n* Presence of severe visual or hearing impairment, or other physical conditions that may interfere with the completion of the study.\n* Participation in any other clinical trial within the past 3 months.\n* Having received transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), light therapy, or having taken medications that could significantly affect cognitive function (e.g., nootropics, psychoactive drugs, anticholinergic drugs, benzodiazepines) for any reason within the past 6 months.\n* History of alcohol dependence or substance abuse.\n* Consumption of alcohol or other substances that affect cognitive function, such as caffeine or cocaine, within 24 hours prior to the cognitive assessment.\n\nAny other conditions that the investigator deems unsuitable for participation in this study.","ALL","60

doses of Computerized Cognitive Training (CCT) in improving cognitive function among patients with Mild Cognitive Impairment (MCI), and to explore the potential optimal intervention dose.\n\nTo analyze the interaction between individual characteristics and the intervention dose of CCT.\n\nTo compare the improvement in functional activity ability of MCI patients among different CCT intervention dose groups.\n\nTo compare the symptoms of depression and anxiety among different CCT intervention dose groups.\n\nTo evaluate the adherence to different doses of CCT intervention.\n\nParticipants will:\n\nReceive CCT intervention at varying durations and frequencies over a 12-week period, and will be followed up for cognitive function, functional activity ability,
