  "img_finding": "Image findings: ventricular volume measures 26,178 mm³, 44.3% below the reference mean. With a Z-score of -1.29 (9.9th percentile), this represents mild atrophy; whole brain volume measures 887,229 mm³, 13.8% below the reference mean. With a Z-score of -1.81 (3.5th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 88.8 years. Gender is Male. Education: 11 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Musculoskeletal; Renal-Genitourinary; Major Surgical Procedures. MMSE: 26.0. Logical Memory: 3.0. APOEε4 alleles: 0.0. Biomarker levels: Total tau: 436.30 pg/mL (significant elevated); Phosphorylated tau: 40.96 pg/mL (significant elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The data shows mild to moderate brain atrophy, particularly in ventricular and whole brain volumes, along with significantly elevated T-tau and P-tau levels, which are biomarkers for neurodegeneration. The MMSE score of 26 is borderline but still within the normal range for age, though the atrophy and biomarker elevations suggest early pathological changes.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to borderline MMSE but strong biomarker and atrophy evidence)",
