With a Z-score of 0.48 (68.3th percentile), this represents normal volume ; whole brain volume measures 1,100,460 mm³, 2.0% above the reference mean. With a Z-score of 0.25 (60.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 22 suggests mild cognitive impairment (MCI) rather than dementia. The absence of APOE4 reduces Alzheimer's risk but does not rule out MCI.  \nDiagnosis: MCI  \nConfidence: Medium",
