With a Z-score of -0.95 (17.1th percentile), this represents normal volume ; hippocampal volume measures 7,876 mm³, 4.2% above the reference mean. With a Z-score of 0.41 (65.9th percentile), this represents normal volume ; whole brain volume measures 1,041,220 mm³, 3.5% below the reference mean. With a Z-score of -0.46 (32.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 27) are also within normal limits for age, and APOE4 status (heterozygous) does not strongly indicate elevated risk without other clinical or biomarker evidence.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
