  "gpt_diagnosis": "Reasoning: The MMSE score of 25 is within the normal range (typically 24-30), but the MoCA score of 19 is below the cutoff for normal cognition (typically ≥26), suggesting possible cognitive impairment. Normal biomarkers (T-tau, P-tau, AV45) and no APOE4 allele reduce the likelihood of Alzheimer's pathology, but the discrepancy between MMSE and MoCA warrants further evaluation.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (due to conflicting MMSE/MoCA results but normal biomarkers)",
