  "gpt_diagnosis": "Reasoning: The MMSE score of 28 and MoCA score of 25 are within normal ranges, suggesting intact cognitive function. However, the presence of one APOE4 allele and moderate amyloid burden (AV45) indicates elevated Alzheimer's risk, but current cognitive performance does not meet criteria for impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting biomarkers and normal cognitive scores in an older adult)",
