  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal limits (Z-score -0.11, 45.5th percentile), and biomarkers (T-tau, P-tau, AV45) are normal. Cognitive scores are borderline (MMSE 29 is normal, MoCA 24 is slightly below typical cutoff for MCI). No APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MoCA 24 is slightly concerning, but other markers strongly support normal cognition)",
