  "text_data": "Age is 75.7 years. Gender is Male. Education: 14 years. MMSE: 29.0. MoCA: 21.0. Logical Memory: 8.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.97 SUVR (normal ). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.67). The MMSE score of 29 is normal, but the MoCA score of 21 suggests mild cognitive impairment (MCI). No amyloid pathology (AV45 normal) and no APOE4 risk allele further support MCI rather than dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
