With a Z-score of 3.05 (99.9th percentile), this represents profound enlargement; whole brain volume measures 985,325 mm³, 4.3% below the reference mean. With a Z-score of -0.56 (28.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 3.05), indicating substantial atrophy, while whole brain volume is within normal limits (Z-score -0.56). The cognitive scores (MMSE 22, MoCA 19) are below expected norms for age, suggesting cognitive impairment.  \nDiagnosis: Dementia  \nConfidence: High",
