  "text_data": "Age is 81.7 years. Gender is Female. Education: 14 years. MMSE: 30.0. MoCA: 27.0. Logical Memory: 18.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.27 SUVR (mild elevated); Amyloid beta: 1003.00 pg/mL (normal ); Total tau: 341.10 pg/mL (mild elevated); Phosphorylated tau: 31.12 pg/mL (mild elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal range, and cognitive scores (MMSE 30, MoCA 27) are intact. Biomarkers show mild elevations in tau and AV45, but Aβ is normal, suggesting possible early neurodegenerative changes without significant cognitive impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild biomarker abnormalities despite normal cognition)",
