With a Z-score of 0.64 (74.0th percentile), this represents normal volume ; whole brain volume measures 851,492 mm³, 17.3% below the reference mean. With a Z-score of -2.26 (1.2th percentile), this represents significant atrophy. ",

Laboratory findings: Serum Glucose: 145.00 (profound elevated); Creatine Kinase: 569.00 (profound elevated); GGT: 68.00 (profound elevated); ALT (SGPT): 39.00 (significant elevated); AST (SGOT): 38.00 (profound elevated).

  "gpt_diagnosis": "Reasoning: The whole brain volume shows significant atrophy (Z-score -2.26, 1.2th percentile), which is concerning for neurodegeneration, but the MMSE score of 27 is within the normal range, suggesting preserved cognitive function. The absence of APOE4 reduces genetic risk but does not rule out sporadic Alzheimer's or other dementias.  \n\nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (due to conflicting imaging and cognitive findings; further clinical correlation needed)",
