With a Z-score of -0.05 (48.2th percentile), this represents normal volume ; whole brain volume measures 919,270 mm³, 5.7% below the reference mean.

  "gpt_diagnosis": "Reasoning: The MoCA score of 9.0 is significantly below the typical cutoff for cognitive impairment (<26), strongly suggesting cognitive dysfunction. While brain volumes are within normal ranges for age, the severe cognitive deficit is more indicative of dementia rather than MCI or normal aging.  \n\nDiagnosis: **Dementia**  \nConfidence: **High**",
