With a Z-score of -1.21 (11.4th percentile), this represents mild atrophy; whole brain volume measures 967,173 mm³, 6.0% below the reference mean. With a Z-score of -0.79 (21.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The patient shows mild ventricular atrophy (Z-score -1.21) but normal whole brain volume (Z-score -0.79). Cognitive testing (MMSE 24, MoCA 21) indicates mild impairment, consistent with MCI. The presence of one APOE4 allele increases Alzheimer's risk but is not definitive.  \nDiagnosis: MCI  \nConfidence: Medium",
