  "text_data": "Age is 77.1 years. Gender is Male. Education: 12 years. MMSE: 28.0. MoCA: 23.0. Logical Memory: 14.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.89). Cognitive scores are mixed (MMSE 28.0 is normal, MoCA 23.0 suggests mild impairment), but no APOE4 risk allele is present.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (MoCA suggests impairment, but hippocampal volume is not strongly indicative of neurodegeneration)",
