  "gpt_diagnosis": "Reasoning: The hippocampal and whole brain volumes are within normal ranges (Z-scores close to 0), and the MMSE score of 30 is intact. However, the MoCA score of 24 suggests mild cognitive impairment (MCI), as it falls below the typical cutoff of 26. The absence of APOE4 reduces Alzheimer's risk but does not rule out MCI.  \nDiagnosis: MCI  \nConfidence: Medium",
