  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is above the reference mean (Z-score 0.68), indicating no significant atrophy. Cognitive scores (MMSE 30, MoCA 25) are within normal limits for age, and the presence of one APOE4 allele does not necessarily indicate impairment.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
