With a Z-score of -0.99 (16.1th percentile), this represents normal volume ; whole brain volume measures 1,022,180 mm³, 5.3% below the reference mean. With a Z-score of -0.69 (24.6th percentile), this represents normal volume . ",
  "text_data": "Age is 79.3 years. Gender is Male. Education: 14 years. MMSE: 27.0. Logical Memory: 13.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 27 is within the normal range (≥26). However, the presence of two APOE4 alleles increases Alzheimer's risk, but current cognitive and structural data do not indicate impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to APOE4 risk but normal clinical and imaging findings)",
