With a Z-score of -0.54 (29.4th percentile), this represents normal volume ; hippocampal volume measures 7,052 mm³, 0.9% below the reference mean. With a Z-score of -0.08 (46.8th percentile), this represents normal volume ; whole brain volume measures 930,404 mm³, 4.5% below the reference mean. With a Z-score of -0.57 (28.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges, with Z-scores close to the mean. However, the MoCA score of 23 suggests mild cognitive impairment, while the MMSE of 30 is normal. The discrepancy between MMSE and MoCA, along with the presence of one APOE4 allele, raises suspicion of early cognitive decline.  \nDiagnosis: MCI  \nConfidence: Medium",
