With a Z-score of 0.49 (68.6th percentile), this represents normal volume ; whole brain volume measures 921,163 mm³, 1.3% above the reference mean. With a Z-score of 0.14 (55.6th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and cognitive scores (MMSE 26, MoCA 24) are borderline but not strongly indicative of impairment for a 91-year-old. No APOE4 allele is present, reducing genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to age-related variability in cognitive scores)",
