  "gpt_diagnosis": "Reasoning: The hippocampal volume is above the reference mean, cognitive scores (MMSE and MoCA) are within normal ranges, and biomarker data (APOE4 negative, normal P-tau and AV45) do not strongly suggest Alzheimer's pathology. Mildly elevated T-tau is non-specific and could be due to other factors.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
