With a Z-score of 0.02 (50.8th percentile), this represents normal volume ; whole brain volume measures 862,050 mm³, 16.2% below the reference mean. With a Z-score of -2.13 (1.7th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.13, 1.7th percentile) despite normal ventricular volume. Cognitive testing reveals a discrepancy between MMSE (normal) and MoCA (mild impairment), which is common in early neurodegenerative processes. The absence of APOE4 reduces Alzheimer's risk but doesn't exclude it.  \nDiagnosis: MCI  \nConfidence: Medium",
