With a Z-score of 2.65 (99.6th percentile), this represents significant enlargement; whole brain volume measures 815,746 mm³, 20.7% below the reference mean. With a Z-score of -2.72 (0.3th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (Z-score 2.65) and whole brain atrophy (Z-score -2.72), consistent with advanced neurodegeneration. The MMSE score of 22.0, combined with the structural changes and APOE4 carrier status, strongly suggests dementia.  \nDiagnosis: Dementia  \nConfidence: High",
