With a Z-score of -0.09 (46.6th percentile), this represents normal volume ; whole brain volume measures 928,494 mm³, 0.0% above the reference mean. With a Z-score of 0.00 (50.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 30/30 indicates no cognitive impairment. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
