With a Z-score of -1.21 (11.4th percentile), this represents mild atrophy; whole brain volume measures 985,969 mm³, 1.6% below the reference mean. With a Z-score of -0.27 (39.5th percentile), this represents normal volume . ",

Cognitive scores are mixed (MMSE 29 is normal, MoCA 23 suggests mild impairment), but APOE4-negative status and preserved MMSE reduce dementia likelihood.  \nDiagnosis: MCI  \nConfidence: Medium",
