With a Z-score of 2.56 (99.5th percentile), this represents significant enlargement; whole brain volume measures 988,286 mm³, 8.4% below the reference mean. With a Z-score of -1.10 (13.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (106.9% above reference mean, Z-score 2.56) and mild whole brain atrophy (8.4% below reference mean, Z-score -1.10), consistent with advanced neurodegeneration. The MMSE score of 17 (indicating moderate-severe cognitive impairment) and APOE4 homozygosity further support a dementia diagnosis.  \n\nDiagnosis: **Dementia**  \nConfidence: **High**",
