With a Z-score of -0.14 (44.5th percentile), this represents normal volume ; whole brain volume measures 990,892 mm³, 3.7% below the reference mean. With a Z-score of -0.49 (31.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,607 mm³, 9.1% below the reference mean. With a Z-score of -0.60 (27.5th percentile), this represents normal volume ; fusiform gyrus volume measures 18,390 mm³, 1.8% above the reference mean. With a Z-score of 0.16 (56.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,621 mm³, 2.2% above the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are all within normal ranges based on Z-scores and percentiles. However, the MoCA score of 21 suggests mild cognitive impairment (MCI), while the MMSE score of 30 is normal. The discrepancy between MoCA and MMSE, along with normal imaging, points to possible MCI rather than dementia.  \nDiagnosis: MCI  \nConfidence: Medium (due to conflicting cognitive scores but normal imaging)",
