With a Z-score of -0.24 (40.4th percentile), this represents normal volume ; whole brain volume measures 875,246 mm³, 5.7% below the reference mean. With a Z-score of -0.68 (24.7th percentile), this represents normal volume . ",
  "text_data": "Age is 85.6 years. Gender is Female. Education: 18 years. MMSE: 26.0. Logical Memory: 0.0. Laboratory findings: Basophils: 0.13 (profound elevated); Basophils: 1.60 (significant elevated); Total Protein: 8.30 (profound elevated); Albumin: 4.80 (significant elevated); Triglycerides (GPO): 552.00 (profound elevated).

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 26 is borderline but still within the normal range for cognitive screening. The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MMSE is slightly low for age, but other markers are normal)",
