With a Z-score of 0.20 (57.8th percentile), this represents normal volume ; hippocampal volume measures 7,265 mm³, 3.9% below the reference mean. With a Z-score of -0.38 (35.2th percentile), this represents normal volume ; whole brain volume measures 1,109,330 mm³, 2.8% above the reference mean. With a Z-score of 0.36 (64.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges, with only slight deviations from the reference mean. Cognitive scores (MMSE 29, MoCA 27) are also within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
