Olfactory deficit is prevalent at the very early stage in the Alzheimers disease. The pathological changes occur in the medial temporal lobe, including the primary olfactory cortex (POC) and hippocampus result in the malfunction of olfaction as well as the cognitive functions. In this study, we will systemically measure the POC and hippocampus volume in the AD and normal subjects and statistic the activation voxels in these regions, so that to investigate the relationship of the functional and anatomical changes at the POC and hippocampus regions.
