With a Z-score of -0.43 (33.3th percentile), this represents normal volume ; whole brain volume measures 874,894 mm³, 5.7% below the reference mean. With a Z-score of -0.69 (24.5th percentile), this represents normal volume . ",
  "text_data": "Age is 82.4 years. Gender is Female. Education: 20 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Gastrointestinal; Renal-Genitourinary; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 28.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 28 is within the normal cognitive range (≥26). The presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to normal imaging and MMSE, but age and APOE4 status warrant caution)",
