With a Z-score of 4.08 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 6,226 mm³, 4.1% below the reference mean. With a Z-score of -0.33 (37.0th percentile), this represents normal volume ; whole brain volume measures 975,438 mm³, 5.1% above the reference mean. With a Z-score of 0.61 (72.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (Z-score 4.08), which is a strong indicator of neurodegeneration, but hippocampal and whole brain volumes are within normal ranges. The MMSE score of 29 is normal, but the MoCA score of 20 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces genetic risk but does not rule out MCI.  \nDiagnosis: MCI  \nConfidence: Medium",
