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, but the MoCA score of 25 suggests mild cognitive inefficiency, though not severe enough for MCI or dementia. APOE4 carrier status increases Alzheimer's risk but does not confirm pathology.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to borderline MoCA score and APOE4 status, but no structural or severe cognitive deficits)",
