With a Z-score of 0.05 (51.9th percentile), this represents normal volume ; whole brain volume measures 1,067,920 mm³, 1.1% below the reference mean. With a Z-score of -0.14 (44.5th 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",
