  "gpt_diagnosis": "Reasoning: The MMSE score of 30 is within the normal range, and the MoCA score of 25 is slightly below the typical cutoff of 26, suggesting possible mild cognitive changes. However, all biomarkers (T-tau, P-tau, AV45) are normal, and there is no APOE4 risk allele, making significant neurodegeneration unlikely.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MoCA score but otherwise normal biomarkers and MMSE)",
