With a Z-score of 12.24 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 4,415 mm³, 37.3% below the reference mean. With a Z-score of -20.57 (0.0th percentile), this represents profound atrophy; whole brain volume measures 984,749 mm³, 8.2% above the reference mean. With a Z-score of 0.92 (82.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The data shows profound hippocampal atrophy (Z-score -20.57) and ventricular enlargement (Z-score 12.24), both strong indicators of neurodegeneration. Combined with low cognitive scores (MMSE 20, MoCA 11), this suggests significant cognitive impairment consistent with dementia.  \n\nDiagnosis: Dementia  \nConfidence: High",
