With a Z-score of 0.23 (59.2th percentile), this represents normal volume ; whole brain volume measures 1,005,680 mm³, 6.8% below the reference mean. With a Z-score of -0.89 (18.8th percentile), this represents normal volume . ",
  "text_data": "Age is 79.7 years. Gender is Male. Education: 16 years. Handedness: Right. Race: White. MMSE: 28.0. MoCA: 22.0. Logical Memory: 5.0. APOEε4 alleles: 0.0. Biomarker levels: Flobetaben (FBB): 0.96 SUVR (mild reduced). ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, though whole brain volume is slightly below the mean. The MMSE score is normal (28/30), but the MoCA score (22/30) suggests mild cognitive impairment (MCI), particularly given the age. The absence of APOE4 reduces Alzheimer's genetic risk but does not rule out MCI.  \nDiagnosis: MCI  \nConfidence: Medium",
