With a Z-score of -0.73 (23.4th percentile), this represents normal volume ; whole brain volume measures 1,032,790 mm³, 6.0% above the reference mean. With a Z-score of 0.75 (77.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 30 indicates intact cognitive function. Biomarkers (Aβ normal, T-tau mildly reduced, P-tau normal) do not suggest Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
