  "gpt_diagnosis": "Reasoning: The patient has normal cognitive scores (MMSE and MoCA both 30/30) and only mild elevation in AV45 (amyloid PET), suggesting early amyloid deposition but no significant cognitive impairment. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild AV45 elevation but preserved cognition)",
