With a Z-score of -0.56 (28.8th percentile), this represents normal volume ; whole brain volume measures 1,020,260 mm³, 4.7% above the reference mean. With a Z-score of 0.59 (72.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges, and the MMSE score of 29 indicates intact cognitive function. The presence of one APOE4 allele increases Alzheimer's risk but does not currently manifest as cognitive impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
