With a Z-score of -0.07 (47.2th percentile), this represents normal volume ; hippocampal volume measures 6,081 mm³, 6.4% below the reference mean. With a Z-score of -0.51 (30.5th percentile), this represents normal volume ; whole brain volume measures 894,522 mm³, 3.6% below the reference mean. With a Z-score of -0.44 (33.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,129 mm³, 9.6% below the reference mean. With a Z-score of -0.52 (30.1th percentile), this represents normal volume ; fusiform gyrus volume measures 14,354 mm³, 10.9% below the reference mean. With a Z-score of -0.82 (20.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,892 mm³, 0.8% below the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges (Z-scores between -0.07 and -0.82, percentiles 20.6–47.3). Cognitive scores (MMSE 29, MoCA 29) are intact, and there is no APOE4 genetic risk. No significant atrophy or cognitive impairment is present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
