With a Z-score of 2.13 (98.3th percentile), this represents significant enlargement; hippocampal volume measures 4,565 mm³, 29.7% below the reference mean. With a Z-score of -2.38 (0.9th percentile), this represents significant atrophy; whole brain volume measures 1,001,380 mm³, 7.9% above the reference mean. With a Z-score of 0.95 (82.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The significant hippocampal atrophy (Z-score -2.38) and ventricular enlargement (Z-score 2.13) are strong indicators of neurodegeneration, consistent with Alzheimer's pathology. The MMSE (25) and MoCA (23) scores suggest mild cognitive impairment, though not severe enough for a dementia diagnosis.  \n\n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **High**",
