  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range, but the MoCA score of 21 suggests mild cognitive impairment (MCI). The brain volume is slightly reduced but still within normal limits, and the absence of APOE4 reduces Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
