With a Z-score of -0.16 (43.7th percentile), this represents normal volume ; whole brain volume measures 985,221 mm³, 8.7% below the reference mean. With a Z-score of -1.13 (12.9th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.13, 12.9th percentile) but normal ventricular volume. The MMSE score of 28 is within the normal range, and there is no significant cognitive impairment reported. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
