With a Z-score of 0.44 (66.8th percentile), this represents normal volume ; hippocampal volume measures 6,759 mm³, 5.0% below the reference mean. With a Z-score of -0.46 (32.3th percentile), this represents normal volume ; whole brain volume measures 951,606 mm³, 2.4% below the reference mean. With a Z-score of -0.30 (38.3th percentile), this represents normal volume . ",

Cognitive scores (MMSE 27, MoCA 26) are also within normal limits for age, and there is no evidence of amyloid pathology (AV45 normal) or genetic risk (APOE4 negative).  \nDiagnosis: CN (Cognitively Normal)  \nConf",
