With a Z-score of -0.35 (36.2th percentile), this represents normal volume ; whole brain volume measures 961,652 mm³, 10.9% below the reference mean. With a Z-score of -1.42 (7.8th percentile), this represents mild atrophy. ",
  "text_data": "Age is 75.5 years. Gender is Male. Education: 12 years. MMSE: 29.0. Laboratory findings: Triglycerides (GPO): 292.00 (profound elevated); GGT: 49.00 (profound elevated); AST (SGOT): 33.00 (significant elevated). APOEε4 alleles: 2.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, but the whole brain volume shows mild atrophy (Z-score -1.42, 7.8th percentile). Despite this, cognitive performance (MMSE 29/30) remains intact, and the presence of two APOE4 alleles increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild atrophy but preserved cognition)",
