With a Z-score of 0.93 (82.4th percentile), this represents normal volume ; whole brain volume measures 1,142,910 mm³, 17.3% above the reference mean. With a Z-score of 2.17 (98.5th percentile), this represents significant enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits (Z-score 0.93), and the whole brain volume is significantly above the reference mean (Z-score 2.17), suggesting no significant atrophy. The MMSE score of 30 is perfect, indicating no cognitive impairment. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
