With a Z-score of -0.11 (45.7th percentile), this represents normal volume ; whole brain volume measures 937,358 mm³, 1.0% above the reference mean. With a Z-score of 0.12 (54.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes 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 alone indicate pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
