Characterization of disease-related covariance topographies with SSMPCA toolbox: effects of spatial normalization and PET scanners.

abstract：:Depressive symptoms often coexist with memory deficits in older adults and also are associated with incident cognitive decline in the elderly. However, little is known about the neural correlates of the association between depressive symptoms and memory deficits in nondemented elderly. Fifteen amnestic mild cognitive ...
