With a Z-score of -0.52 (30.0th percentile), this represents normal volume ; whole brain volume measures 1,001,500 mm³, 2.7% below the reference mean. With a Z-score of -0.35 (36.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 23 is borderline but not definitively indicative of dementia. The absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
