With a Z-score of -1.42 (7.8th percentile), this represents mild atrophy; whole brain volume measures 1,021,140 mm³, 0.8% below the reference mean. With a Z-score of -0.10 (45.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy (Z-score -1.42), but whole brain volume is normal (Z-score -0.10). The MMSE score of 28 is within the normal range, and while APOE4 homozygosity increases Alzheimer's risk, there are no clear cognitive deficits.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild atrophy but preserved cognition and normal MMSE)",
