With a Z-score of -2.06 (2.0th percentile), this represents significant atrophy; whole brain volume measures 874,633 mm³, 12.7% below the reference mean. With a Z-score of -2.16 (1.5th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The hippocampal and whole brain volumes show significant atrophy (Z-scores < -2.0), which is strongly associated with neurodegenerative disease. The cognitive scores (MMSE 24, MoCA 18) indicate mild cognitive impairment, and the absence of APOE4 does not rule out dementia given the structural and functional deficits.  \nDiagnosis: **Dementia**  \nConfidence: **High**",
