With a Z-score of 0.11 (54.5th percentile), this represents normal volume ; hippocampal volume measures 7,922 mm³, 1.3% below the reference mean. With a Z-score of -0.13 (44.8th percentile), this represents normal volume ; whole brain volume measures 1,209,760 mm³, 6.6% above the reference mean. With a Z-score of 0.94 (82.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges, with no significant atrophy. The MMSE score of 30 is normal, but the MoCA score of 24 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: MCI  \nConfidence: Medium",
