Entorhinal cortex and parahippocampus volume reductions impact olfactory decline in aged subjects

ConclusionOur results indicate that olfactory decline may be directly reflected in the medial temporal regions as reduced parahippocampus volumes, rather than as morphological changes in the entorhinal cortex and hippocampus. The parahippocampus may play an important role in the association between memory retrieval and olfactory identification.
