With a Z-score of -0.52 (30.1th percentile), this represents normal volume ; whole brain volume measures 838,052 mm³, 9.7% below the reference mean. With a Z-score of -1.17 (12.2th percentile), this represents mild atrophy. ",
  "text_data": "Age is 83.9 years. Gender is Female. Education: 17 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Gastrointestinal; Renal-Genitourinary; Smoking. MMSE: 30.0. MoCA: 29.0. Logical Memory: 19.0. APOEε4 alleles: 0.0.

  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, while the whole brain volume shows mild atrophy. Cognitive scores (MMSE and MoCA) are in the normal range, and there is no APOE4 genetic risk factor present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy could be age-related, but cognitive scores are intact)",
