  "gpt_diagnosis": "Reasoning: The hippocampal volume is severely reduced (68.2% below mean, Z-score -5.89), indicating profound atrophy. Combined with cognitive impairment (MMSE 22, MoCA 14) and elevated amyloid (AV45+), this strongly suggests Alzheimer's pathology.  \nDiagnosis: Dementia  \nConfidence: High",
