With a Z-score of -0.60 (27.6th percentile), this represents normal volume ; whole brain volume measures 904,288 mm³, 2.6% below the reference mean. With a Z-score of -0.31 (37.9th percentile), this represents normal volume . ",
  "text_data": "Age is 84.1 years. Gender is Female. Education: 18 years. MMSE: 26.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 26 is borderline but still within the normal range for age. The absence of APOE4 alleles reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MMSE is slightly low for age, but structural imaging is unremarkable)",
