With a Z-score of -0.08 (46.8th percentile), this represents normal volume ; whole brain volume measures 931,192 mm³, 0.3% above the reference mean. With a Z-score of 0.04 (51.6th 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 confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
