With a Z-score of 1.35 (91.2th percentile), this represents mild enlargement; whole brain volume measures 1,094,250 mm³, 12.3% above the reference mean. With a Z-score of 1.54 (93.9th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (59.1% above reference mean), and whole brain volume is moderately enlarged (12.3% above reference mean), but cognitive scores (MMSE 30, MoCA 29) are intact, and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (structural changes are present but not accompanied by cognitive decline or genetic risk)",
