With a Z-score of -0.91 (18.3th percentile), this represents normal volume ; hippocampal volume measures 6,539 mm³, 8.1% below the reference mean. With a Z-score of -0.74 (22.9th percentile), this represents normal volume ; whole brain volume measures 909,663 mm³, 6.7% below the reference mean. With a Z-score of -0.84 (20.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,223 mm³, 12.2% below the reference mean. With a Z-score of -0.75 (22.6th percentile), this represents normal volume ; fusiform gyrus volume measures 15,998 mm³, 6.0% below the reference mean. With a Z-score of -0.54 (29.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,398 mm³, 4.0% below the reference mean. With a Z-score of -0.35 (36.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 25) are also within normal limits for age, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
