With a Z-score of 0.42 (66.1th percentile), this represents normal volume ; whole brain volume measures 1,095,870 mm³, 3.4% below the reference mean. With a Z-score of -0.48 (31.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 30.0 indicates no cognitive impairment. The presence of one APOE4 allele increases Alzheimer's risk but does not currently indicate impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
