With a Z-score of 1.63 (94.9th percentile), this represents moderate enlargement; hippocampal volume measures 5,940 mm³, 14.8% below the reference mean. With a Z-score of -1.27 (10.1th percentile), this represents mild atrophy; whole brain volume measures 1,161,800 mm³, 12.9% above the reference mean. With a Z-score of 1.69 (95.4th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The data shows mild hippocampal atrophy (Z-score -1.27) and moderate ventricular enlargement (Z-score 1.63), which are structural changes often associated with cognitive decline. However, the MMSE score of 30 is normal, while the MoCA score of 23 suggests mild cognitive impairment (MCI). The presence of one APOE4 allele increases Alzheimer's risk but does not confirm dementia.  \n\nDiagnosis: **MCI**  \nConfidence: **Medium** (due to conflicting MMSE/MoCA scores and structural changes without clear functional impairment)",
