  "gpt_diagnosis": "**Reasoning:** The MMSE score of 22 and MoCA score of 19 suggest mild cognitive impairment, as both scores are below typical cutoffs for normal cognition (MMSE <24, MoCA <26). The absence of APOE4 and normal AV45 (amyloid PET) reduce the likelihood of Alzheimer's pathology, but age-related neurodegeneration or other causes of MCI remain possible.  \n\n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium (cognitive scores indicate impairment, but normal amyloid reduces certainty of Alzheimer's etiology)",
