With a Z-score of 0.53 (70.2th percentile), this represents normal volume ; whole brain volume measures 1,131,400 mm³, 4.8% above the reference mean. With a Z-score of 0.63 (73.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The ventricular and whole brain volumes are within normal ranges (Z-scores close to 0, percentiles ~70th), and the MMSE score of 30/30 indicates no cognitive impairment. The presence of one APOE4 allele increases Alzheimer’s risk but does not confirm pathology in the absence of clinical or structural deficits.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
