With a Z-score of -0.19 (42.6th percentile), this represents normal volume ; whole brain volume measures 957,577 mm³, 1.8% below the reference mean. With a Z-score of -0.22 (41.3th percentile), this represents normal volume . ",
  "text_data": "Age is 76.2 years. Gender is Female. Education: 18 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Alcohol Abuse; Smoking. MMSE: 29.0. MoCA: 21.0. Logical Memory: 14.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, indicating no significant atrophy. However, the MoCA score of 21.0 is below the typical cutoff for normal cognition (usually 26+), suggesting possible cognitive impairment despite the normal MMSE (29.0). The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (due to discrepancy between MMSE and MoCA, but MoCA is more sensitive to early cognitive decline)",
