  "text_data": "Age is 79.8 years. Gender is Male. Education: 15 years. MMSE: 30.0. MoCA: 22.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.21 SUVR (normal ); Amyloid beta: 1103.00 pg/mL (normal ); Total tau: 275.90 pg/mL (normal ); Phosphorylated tau: 23.93 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 30 is normal, but the MoCA score of 22 suggests mild cognitive impairment (MCI). Biomarkers (Aβ, T-tau, P-tau, AV45) are all normal, and there is no APOE4 risk allele, which reduces the likelihood of Alzheimer's pathology.  \nDiagnosis: MCI  \nConfidence: Medium  \n\n(Note: The discrepancy between MMSE and MoCA is notable—MMSE is less sensitive to early cognitive changes, while MoCA often detects MCI better. The normal biomarkers suggest non-Alzheimer's etiology, but the cognitive scores still indicate impairment.)",
