  "gpt_diagnosis": "Reasoning: The patient shows mild reductions in Aβ and mild elevations in P-tau, which are indicative of early Alzheimer's pathology. However, cognitive scores (MMSE 25, MoCA 27) are within normal ranges, suggesting no significant cognitive impairment at this stage.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting biomarkers and normal cognitive scores but presence of early pathological changes)",
