With a Z-score of 0.80 (79.0th percentile), this represents normal volume ; hippocampal volume measures 7,984 mm³, 3.9% above the reference mean. With a Z-score of 0.44 (66.9th percentile), this represents normal volume ; whole brain volume measures 1,037,000 mm³, 0.8% above the reference mean. With a Z-score of 0.09 (53.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,684 mm³, 5.4% below the reference mean. With a Z-score of -0.42 (33.9th percentile), this represents normal volume ; fusiform gyrus volume measures 18,922 mm³, 3.9% above the reference mean. With a Z-score of 0.44 (67.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,167 mm³, 1.7% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 28) are also within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
