  "gpt_diagnosis": "Reasoning: The patient shows significant cognitive impairment with an MMSE of 21 (below the typical cutoff of 24 for dementia) and a MoCA of 15 (well below the typical cutoff of 26 for MCI). The presence of two APOE4 alleles increases the risk for Alzheimer's disease, but the normal AV45 (amyloid PET scan) suggests no significant amyloid deposition.  \nDiagnosis: Dementia (likely non-Alzheimer's etiology, such as vascular or mixed dementia)  \nConfidence: Medium (cognitive scores strongly suggest dementia, but normal AV45 complicates the Alzheimer's diagnosis)",
