With a Z-score of 0.93 (82.3th percentile), this represents normal volume ; whole brain volume measures 912,435 mm³, 1.7% below the reference mean. With a Z-score of -0.20 (41.9th percentile), this represents normal volume . ",
  "text_data": "Age is 87.2 years. Gender is Female. Education: 16 years. MMSE: 24.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly elevated but still within the normal range, and whole brain volume is only marginally below the reference mean. The MMSE score of 24 is borderline but not definitively indicative of dementia, especially given the patient's advanced age. The absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE and age-related considerations)",
