With a Z-score of 2.61 (99.5th percentile), this represents significant enlargement; whole brain volume measures 734,116 mm³, 28.7% below the reference mean. With a Z-score of -3.76 (0.0th percentile), this represents profound atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (Z-score 2.61) and profound whole brain atrophy (Z-score -3.76), which are strong indicators of neurodegeneration. Despite relatively preserved MMSE (26) and borderline MoCA (21), the structural changes are severe and consistent with dementia.  \nDiagnosis: Dementia  \nConfidence: High",
