With a Z-score of 2.95 (99.8th percentile), this represents significant enlargement; whole brain volume measures 845,372 mm³, 8.9% below the reference mean. With a Z-score of -1.07 (14.2th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The significant ventricular enlargement (Z-score 2.95) and mild whole brain atrophy (Z-score -1.07) suggest structural brain changes consistent with neurodegeneration. The MMSE score of 24.0 (borderline impaired) in an 86-year-old female without APOE4 risk allele supports mild cognitive impairment rather than normal aging or severe dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
