With a Z-score of 0.36 (64.2th percentile), this represents normal volume ; whole brain volume measures 906,318 mm³, 2.4% below the reference mean. With a Z-score of -0.28 (38.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, but the MMSE score of 21 suggests mild cognitive impairment (MCI), while the MoCA score of 24 is borderline normal. Given the age (88.5) and absence of APOE4, this is more likely age-related cognitive decline rather than dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
