With a Z-score of 4.24 (100.0th percentile), this represents profound enlargement; whole brain volume measures 958,309 mm³, 15.5% below the reference mean. With a Z-score of -2.20 (1.4th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (Z-score 4.24) and significant whole brain atrophy (Z-score -2.20), consistent with advanced neurodegeneration. The MMSE score of 14 indicates severe cognitive impairment, aligning with structural brain changes.  \nDiagnosis: Dementia  \nConfidence:",
