With a Z-score of 1.74 (95.9th percentile), this represents moderate enlargement; whole brain volume measures 766,180 mm³, 17.5% below the reference mean. With a Z-score of -2.09 (1.8th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant whole brain atrophy (Z-score -2.09) and moderate ventricular enlargement, which are structural changes commonly associated with dementia. The MMSE score of 14.0 is well below the normal range (typically 24-30), indicating severe cognitive impairment.  \n\nDiagnosis: Dementia  \nConfidence: High",
