With a Z-score of 0.57 (71.4th percentile), this represents normal volume ; whole brain volume measures 930,612 mm³, 4.5% below the reference mean. With a Z-score of -0.57 (28.5th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is slightly above the reference mean but still within the normal range (Z-score 0.57), while whole brain volume is slightly below the reference mean but also normal (Z-score -0.57). The MMSE score of 25 is borderline, and the presence of two APOE4 alleles increases Alzheimer's risk, but structural brain changes are not yet significant.  \n**Diagnosis:** Mild Cognitive Impairment (MCI)  \n**Confidence:** Medium",
