With a Z-score of 0.10 (54.0th percentile), this represents normal volume ; hippocampal volume measures 7,045 mm³, 6.8% below the reference mean. With a Z-score of -0.66 (25.4th percentile), this represents normal volume ; whole brain volume measures 989,226 mm³, 8.4% below the reference mean. With a Z-score of -1.08 (13.9th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The hippocampal and whole brain volumes show mild atrophy, but ventricular volume is normal. Cognitive scores (MMSE 27, MoCA 22) suggest mild cognitive impairment, particularly given the MoCA score below the typical cutoff of 26. No APOE4 allele reduces genetic risk but does not rule out neurodegeneration.  \nDiagnosis: MCI  \nConfidence: Medium",
