With a Z-score of -0.41 (34.1th percentile), this represents normal volume ; hippocampal volume measures 7,552 mm³, 5.9% below the reference mean. With a Z-score of -0.59 (27.7th percentile), this represents normal volume ; whole brain volume measures 1,079,410 mm³, 4.9% below the reference mean. With a Z-score of -0.69 (24.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,748 mm³, 12.1% below the reference mean. With a Z-score of -0.84 (20.2th percentile), this represents normal volume ; fusiform gyrus volume measures 20,752 mm³, 4.2% above the reference mean. With a Z-score of 0.35 (63.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 24,008 mm³, 7.1% above the reference mean.

  "text_data": "Age is 62.5 years. Gender is Male. Education: 16 years. MMSE: 30.0. MoCA: 25.0. Laboratory findings: Creatine Kinase: 313.00 (profound elevated); GGT: 58.00 (profound elevated); ALT (SGPT): 34.00 (significant elevated); AST (SGOT): 33.00 (significant elevated).

  "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. The MMSE score of 30 is optimal, and the MoCA score of 25 is within the normal range (though slightly below the typical cutoff of 26, it may still be normal depending on education level). The presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to borderline MoCA score, but no structural or significant cognitive deficits)",
