With a Z-score of 0.53 (70.3th percentile), this represents normal volume ; hippocampal volume measures 7,705 mm³, 1.9% above the reference mean. With a Z-score of 0.19 (57.5th percentile), this represents normal volume ; whole brain volume measures 1,084,680 mm³, 0.5% above the reference mean. With a Z-score of 0.06 (52.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges, with Z-scores close to the mean. Cognitive scores (MMSE and MoCA) are perfect (30/30), and there is no APOE4 genetic risk factor.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
