With a Z-score of 0.13 (55.2th percentile), this represents normal volume ; whole brain volume measures 1,060,150 mm³, 6.6% below the reference mean.

  "text_data": "Age is 64.8 years. Gender is Male. Education: 16 years. MMSE: 19.0. MoCA: 13.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is within normal range, but the whole brain volume is slightly reduced (6.6% below reference mean). Cognitive scores (MMSE 19, MoCA 13) are significantly impaired, consistent with cognitive decline. The presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **Dementia** (likely Alzheimer’s disease given APOE4 status and cognitive deficits despite relatively preserved hippocampal volume).  \nConfidence: **Medium** (imaging is not strongly supportive, but cognitive scores and genetic risk strongly suggest dementia).",
