With a Z-score of 0.74 (77.2th percentile), this represents normal volume ; whole brain volume measures 885,182 mm³, 9.2% below the reference mean. With a Z-score of -1.16 (12.4th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.16) but normal ventricular volume. Combined with an MMSE score of 25 (borderline for mild cognitive impairment) and APOE4 carrier status, this suggests early cognitive decline but not yet dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
