With a Z-score of -0.41 (34.2th percentile), this represents normal volume ; whole brain volume measures 994,981 mm³, 3.3% below the reference mean. With a Z-score of -0.44 (33.2th percentile), this represents normal volume . ",
  "text_data": "Age is 85.3 years. Gender is Male. Education: 20 years. MMSE: 25.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges, and the MMSE score of 25 is borderline but not strongly indicative of cognitive impairment. The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE score in an older individual, but otherwise normal biomarkers)",
