With a Z-score of 0.04 (51.7th percentile), this represents normal volume ; whole brain volume measures 854,872 mm³, 7.9% below the reference mean. With a Z-score of -0.95 (17.2th percentile), this represents normal volume . ",
  "text_data": "Age is 83.0 years. Gender is Female. Education: 15 years. Handedness: Right. Race: Black or African American. Medical history: Cardiovascular; Musculoskeletal; Smoking; Major Surgical Procedures. MMSE: 26.0. MoCA: 18.0. Logical Memory: 5.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "**Reasoning:** The patient shows normal ventricular and whole brain volumes, but the MoCA score of 18 is below the typical cutoff for normal cognition (≥26), suggesting cognitive impairment. The MMSE of 26 is borderline (normal range is typically 24-30), but the MoCA is more sensitive to early cognitive deficits. No APOE4 allele reduces Alzheimer's genetic risk.  \n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (due to borderline MMSE and lack of structural atrophy, but MoCA strongly suggests impairment)",
