With a Z-score of 0.19 (57.4th percentile), this represents normal volume ; hippocampal volume measures 7,653 mm³, 7.6% above the reference mean. With a Z-score of 0.69 (75.6th percentile), this represents normal volume ; whole brain volume measures 919,675 mm³, 5.6% below the reference mean. With a Z-score of -0.71 (23.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,259 mm³, 16.0% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) all fall within normal ranges relative to reference means and Z-scores. However, the MMSE score of 22 suggests mild cognitive impairment, though APOE4-negative status and normal brain volumes reduce the likelihood of Alzheimer's pathology.  \n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium",
