With a Z-score of 0.60 (72.4th percentile), this represents normal volume ; whole brain volume measures 1,082,740 mm³, 5.2% above the reference mean. With a Z-score of 0.68 (75.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal and whole brain volumes are within normal ranges, but the MMSE (24) and MoCA (15) scores indicate cognitive impairment. The absence of APOE4 and reduced AV45 (amyloid burden) suggest lower Alzheimer's risk, but the cognitive scores are concerning.  \n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (due to conflicting biomarkers and cognitive scores)",
