With a Z-score of -0.67 (25.2th percentile), this represents normal volume ; whole brain volume measures 1,015,120 mm³, 6.0% below the reference mean. With a Z-score of -0.77 (22.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, but the MoCA score of 22 suggests mild cognitive impairment (MCI), especially given the age of 78.3 and presence of one APOE4 allele, which is a risk factor for cognitive decline. The MMSE of 27 is borderline but does not strongly contradict MCI.  \nDiagnosis: MCI  \nConfidence: Medium",
