With a Z-score of -1.16 (12.4th percentile), this represents mild atrophy; whole brain volume measures 945,293 mm³, 8.1% below the reference mean. With a Z-score of -1.07 (14.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 81.9 years. Gender is Male. Education: 19 years. MMSE: 24.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows mild atrophy in both ventricular and whole brain volumes, with Z-scores slightly below the reference mean. The MMSE score of 24 is borderline, but the absence of APOE4 reduces genetic risk.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (due to mild atrophy and borderline MMSE, but no strong genetic or severe structural markers)",
