With a Z-score of 1.76 (96.1th percentile), this represents moderate enlargement; whole brain volume measures 904,333 mm³, 7.2% below the reference mean. With a Z-score of -0.91 (18.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The patient shows significant ventricular enlargement (76.9% above reference mean) and slightly reduced whole brain volume (7.2% below reference mean), which are structural changes often seen in dementia. The MMSE score of 12.0 is severely impaired, strongly suggesting cognitive decline beyond normal aging or MCI.  \nDiagnosis: **Dementia**  \nConfidence: **High**",
