With a Z-score of 0.29 (61.4th percentile), this represents normal volume ; hippocampal volume measures 4,350 mm³, 42.5% below the reference mean. With a Z-score of -4.14 (0.0th percentile), this represents profound atrophy; whole brain volume measures 1,080,550 mm³, 0.1% above the reference mean. With a Z-score of 0.01 (50.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (Z-score -4.14, 0th percentile), which is strongly associated with Alzheimer's pathology. The MMSE (24) and MoCA (22) scores indicate mild cognitive impairment, and the presence of two APOE4 alleles increases Alzheimer's risk. Ventricular and whole brain volumes are normal, suggesting focal rather than generalized atrophy.  \n\nDiagnosis: **MCI** (likely due to Alzheimer's pathology)  \nConfidence: **High**",
