With a Z-score of 0.07 (52.8th percentile), this represents normal volume ; hippocampal volume measures 6,154 mm³, 18.6% below the reference mean. With a Z-score of -1.81 (3.5th percentile), this represents moderate atrophy; whole brain volume measures 1,081,660 mm³, 0.2% above the reference mean. With a Z-score of 0.03 (51.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,597 mm³, 12.3% below the reference mean. With a Z-score of -0.83 (20.2th percentile), this represents normal volume ; fusiform gyrus volume measures 17,532 mm³, 6.9% below the reference mean. With a Z-score of -0.59 (27.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,231 mm³, 9.9% below the reference mean.

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows moderate atrophy (Z-score -1.81, 3.5th percentile), which is a strong biomarker for Alzheimer's pathology. The MMSE is normal (29/30), but the MoCA (23/30) suggests mild cognitive impairment, particularly in executive function or visuospatial abilities. The presence of two APOE4 alleles increases Alzheimer's risk.  \n\nDiagnosis: **Mild Cognitive Impairment (MCI)**  \nConfidence: **High**",
