With a Z-score of -3.58 (0.0th percentile), this represents profound atrophy; whole brain volume measures 956,912 mm³, 1.8% below the reference mean. With a Z-score of -0.23 (40.9th percentile), this represents normal volume . ",
  "text_data": "Age is 74.9 years. Gender is Female. Education: 17 years. MMSE: 29.0. MoCA: 25.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows profound hippocampal atrophy (Z-score -3.58, 0.0th percentile) but normal whole brain volume. Cognitive scores are borderline (MoCA 25/30, MMSE 29/30), and APOE4 carrier status increases Alzheimer's risk. Hippocampal atrophy is strongly associated with early Alzheimer's pathology.  \nDiagnosis: **MCI** (mild cognitive impairment, likely due to underlying Alzheimer's pathology)  \nConfidence: **Medium** (high for neurodegeneration, but cognitive scores are not yet in dementia range)",
