With a Z-score of -1.38 (8.4th percentile), this represents mild atrophy; whole brain volume measures 895,818 mm³, 17.0% below the reference mean. With a Z-score of -2.21 (1.4th percentile), this represents significant atrophy. ",
  "text_data": "Age is 77.8 years. Gender is Male. Education: 15 years. MMSE: 30.0. MoCA: 25.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal and whole brain volumes show mild to significant atrophy, but cognitive scores (MMSE: 30, MoCA: 25) remain within normal to borderline ranges, and there is no APOE4 risk allele. The atrophy may reflect aging or early neurodegenerative changes, but current cognitive performance does not meet criteria for MCI or dementia.  \n\nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (due to conflicting imaging and cognitive data, but preserved function suggests no active impairment)",
