With a Z-score of 0.18 (57.0th percentile), this represents normal volume ; whole brain volume measures 877,348 mm³, 5.5% below the reference mean. With a Z-score of -0.66 (25.5th percentile), this represents normal volume . ",
  "text_data": "Age is 89.1 years. Gender is Female. Education: 16 years. MMSE: 27.0. MoCA: 27.0. Logical Memory: 7.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume measurements (ventricular and whole brain) fall within the normal range despite slight deviations from the reference mean. Cognitive scores (MMSE and MoCA) are both 27/30, which are within normal limits for age, and APOE4 status (heterozygous) alone does not confirm pathology.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to normal cognitive scores and brain volumes, but age and APOE4 status warrant monitoring for future decline)",
