With a Z-score of 2.25 (98.8th percentile), this represents significant enlargement; whole brain volume measures 912,309 mm³, 6.4% below the reference mean. With a Z-score of -0.81 (21.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.25) and whole brain volume reduction (Z-score -0.81) indicate substantial atrophy, consistent with neurodegenerative disease. The low MMSE score (17/30) and presence of two APOE4 alleles further support a dementia diagnosis, likely Alzheimer’s disease.  \n\nDiagnosis: Dementia  \nConfidence: High",
