With a Z-score of -0.40 (34.3th percentile), this represents normal volume ; whole brain volume measures 875,564 mm³, 5.7% below the reference mean. With a Z-score of -0.68 (24.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 25 is borderline but not definitively indicative of cognitive impairment. The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
