  "gpt_diagnosis": "Reasoning: The hippocampal volume is severely reduced (42.8% below mean, Z-score -4.18), indicating significant neurodegeneration. Combined with low MMSE (19) and MoCA (8) scores, this strongly suggests cognitive impairment beyond normal aging.  \nDiagnosis: Dementia  \nConfidence: High",
