With a Z-score of -0.05 (48.2th percentile), this represents normal volume ; whole brain volume measures 886,432 mm³, 9.1% below the reference mean. With a Z-score of -1.14 (12.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.14, 12.7th percentile) but normal ventricular volume. The MMSE score of 25 is borderline, but there is no APOE4 genetic risk factor. Mild atrophy and slightly reduced MMSE may suggest early cognitive changes, but not definitive dementia.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
