With a Z-score of 1.36 (91.3th percentile), this represents mild enlargement; whole brain volume measures 989,198 mm³, 12.8% below the reference mean. With a Z-score of -1.81 (3.5th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows moderate whole brain atrophy (Z-score -1.81, 3.5th percentile) and mild ventricular enlargement (Z-score 1.36), which are structural changes consistent with neurodegenerative processes. The MMSE score of 24.0 suggests mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \n\nDiagnosis: MCI  \nConfidence: Medium",
