With a Z-score of -0.13 (44.9th percentile), this represents normal volume ; whole brain volume measures 963,805 mm³, 6.4% below the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, but the MMSE score of 27 is borderline for mild cognitive impairment (MCI). Elevated T-tau and P-tau with mildly reduced Aβ suggest Alzheimer's pathology, though the MMSE is not severely impaired.  \nDiagnosis: MCI  \nConfidence: Medium",
