With a Z-score of 3.99 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 5,660 mm³, 25.1% below the reference mean. With a Z-score of -2.45 (0.7th percentile), this represents significant atrophy; whole brain volume measures 1,130,460 mm³, 4.7% above the reference mean. With a Z-score of 0.61 (73.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The data shows significant hippocampal atrophy (Z-score -2.45) and profound ventricular enlargement (Z-score 3.99), which are strong biomarkers for neurodegenerative disease. However, cognitive scores are mixed (MMSE 29 is normal, MoCA 21 suggests mild impairment), and the absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI  \nConfidence: Medium",
