With a Z-score of 2.49 (99.4th percentile), this represents significant enlargement; whole brain volume measures 953,530 mm³, 11.7% below the reference mean. With a Z-score of -1.51 (6.5th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (103.8% above mean, Z-score 2.49) and moderate whole brain atrophy (11.7% below mean, Z-score -1.51), which are structural changes consistent with neurodegeneration. The MMSE score of 25 is borderline for mild cognitive impairment (MCI), and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
