  "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 the normal range, and cognitive scores (MMSE 30, MoCA 27) are intact. While there are mild elevations in biomarkers (T-tau, P-tau, AV45), these alone do not indicate significant neurodegeneration in the presence of preserved cognition.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild biomarker elevations, but cognition remains unaffected)",
