  "gpt_diagnosis": "Reasoning: The MMSE score of 26 is within the normal range (typically 24-30), but the MoCA score of 18 is below the cutoff for normal cognition (typically <26 suggests impairment). This discrepancy, along with the presence of one APOE4 allele (a risk factor for Alzheimer's), suggests cognitive impairment. The MoCA is more sensitive to early cognitive deficits, particularly in executive function and attention, which are often affected in MCI or early dementia.  \n\nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (due to the discrepancy between MMSE and MoCA, but MoCA is more indicative of early impairment)",
