MMSE: 29.0. MoCA: 26.0. Logical Memory: 5.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.25 SUVR (mild elevated); Amyloid beta: 837.70 pg/mL (normal ); Total tau: 186.60 pg/mL (normal ); Phosphorylated tau: 18.42 pg/mL (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.57). Cognitive scores (MMSE 29, MoCA 26) are normal, and biomarkers (Aβ, T-tau, P-tau) are unremarkable despite mildly elevated AV45. No significant cognitive or structural deficits are present.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
