With a Z-score of -0.01 (49.4th percentile), this represents normal volume ; whole brain volume measures 1,019,810 mm³, 5.5% below the reference mean. With a Z-score of -0.72 (23.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges despite being slightly below the reference mean. The MMSE score of 24 is borderline, suggesting possible cognitive impairment, but not definitive for dementia. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
