  "gpt_diagnosis": "Reasoning: The patient has normal cognitive scores (MMSE and MoCA both 28/30) and no APOE4 alleles, but shows moderately elevated amyloid burden (AV45). The preserved cognitive function despite amyloid burden suggests resilience or early preclinical changes.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (Amyloid elevation raises concern, but cognition remains intact)",
