  "gpt_diagnosis": "Reasoning: The MMSE score of 26 and MoCA score of 23 suggest mild cognitive impairment (MCI), as they are below typical cutoffs for normal cognition (MMSE <27, MoCA <26). The AV45 (amyloid PET) shows moderate elevation, indicating amyloid pathology, but CSF biomarkers (Aβ, T-tau, P-tau) are normal, creating some ambiguity.  \nDiagnosis: MCI  \nConfidence: Medium (due to conflicting amyloid biomarkers and borderline cognitive scores)",
