With a Z-score of 0.16 (56.2th percentile), this represents normal volume ; whole brain volume measures 816,419 mm³, 12.0% below the reference mean. With a Z-score of -1.45 (7.4th percentile), this represents mild atrophy. ",

The MMSE score of 22 suggests cognitive impairment, but not severe enough for dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
