With a Z-score of 4.60 (100.0th percentile), this represents profound enlargement; whole brain volume measures 726,036 mm³, 32.7% below the reference mean. With a Z-score of -4.25 (0.0th percentile), this represents profound atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (192.2% above mean) and whole brain atrophy (32.7% below mean), both with extreme Z-scores (>4 SD from mean). Combined with very low cognitive scores (MMSE 11, MoCA 6), this indicates severe neurodegeneration. The presence of one APOE4 allele further supports Alzheimer's pathology.  \n\nDiagnosis: Dementia (likely Alzheimer’s disease)  \nConfidence: High",
