  "gpt_diagnosis": "Reasoning: The MMSE score of 30 is within the normal range, indicating no significant cognitive impairment. However, mild reductions in Aβ, T-tau, and P-tau suggest early pathological changes, though these are not yet clinically significant.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild biomarker abnormalities despite normal cognition)",
