With a Z-score of 0.56 (71.1th percentile), this represents normal volume ; hippocampal volume measures 7,137 mm³, 5.6% below the reference mean. With a Z-score of -0.54 (29.3th percentile), this represents normal volume ; whole brain volume measures 1,079,790 mm³, 0.0% above the reference mean. With a Z-score of 0.00 (50.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,675 mm³, 10.4% below the reference mean. With a Z-score of -0.70 (24.1th percentile), this represents normal volume ; fusiform gyrus volume measures 19,319 mm³, 2.6% above the reference mean. With a Z-score of 0.22 (58.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,215 mm³, 0.6% below the reference mean. With a Z-score of -0.05 (47.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements (hippocampal, entorhinal cortex, and others) are within normal ranges, with only mild deviations from the reference mean (all Z-scores within normal limits). Cognitive scores (MMSE 29, MoCA 26) are also within normal ranges for age, and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
