With a Z-score of 0.57 (71.6th percentile), this represents normal volume ; whole brain volume measures 1,158,320 mm³, 12.6% above the reference mean. With a Z-score of 1.56 (94.1th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, and the whole brain volume is moderately enlarged, which is atypical for Alzheimer's but not indicative of neurodegeneration. The MMSE score of 30 is perfect, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
