With a Z-score of 0.06 (52.3th percentile), this represents normal volume ; whole brain volume measures 1,152,890 mm³, 6.8% above the reference mean. With a Z-score of 0.88 (81.2th percentile), this represents normal volume . ",

Medical history: Psychiatric; Neurologic; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Respiratory; Dermatologic-Connective Tissue; Musculoskeletal; Endocrine-Metabolic; Renal-Genitourinary; Allergies or Drug Sensitivities; Major Surgical Procedures.

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 25 is borderline but not definitively indicative of cognitive impairment. The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MMSE is slightly low for age, but structural and genetic data support normal cognition)",
