With a Z-score of -1.28 (10.1th percentile), this represents mild atrophy; hippocampal volume measures 6,239 mm³, 3.9% below the reference mean. With a Z-score of -0.32 (37.6th percentile), this represents normal volume ; whole brain volume measures 927,248 mm³, 0.1% below the reference mean. With a Z-score of -0.01 (49.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The ventricular volume shows mild atrophy, but hippocampal and whole brain volumes are within normal ranges. Cognitive scores (MMSE 26, MoCA 24) are borderline but not strongly indicative of dementia, and the absence of APOE4 reduces genetic risk.  \n**Diagnosis:** Mild Cognitive Impairment (MCI)  \n**Confidence:** Medium (due to borderline cognitive scores and mild atrophy, but no strong dementia markers)",
