  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal range (Z-score -0.37), cognitive scores (MMSE 30, MoCA 27) are intact, and all biomarkers (Aβ, tau, AV45) are normal. There is no evidence of cognitive impairment or neurodegenerative pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
