  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range (typically 24-30), and the APOE4 status is negative. While Aβ is mildly elevated, T-tau and P-tau are normal, suggesting minimal Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mildly elevated Aβ, but other markers and cognitive performance are normal)",
