  "gpt_diagnosis": "Reasoning: The MMSE score of 30.0 (perfect) and MoCA score of 27.0 (above the typical cutoff of 26 for MCI) indicate intact cognitive function. The moderate reduction in AV45 (amyloid PET) suggests amyloid pathology, but the absence of cognitive impairment suggests resilience or preclinical Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to the discrepancy between amyloid burden and preserved cognition, which could indicate preclinical AD or resilience)",
