With a Z-score of -0.45 (32.5th percentile), this represents normal volume ; whole brain volume measures 997,342 mm³, 7.6% below the reference mean. With a Z-score of -0.99 (16.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 29 is well within the normal cognitive range (≥26). The presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
