Differences in specific memory disturbances of subcortical dementias and cortical dementias

Differences in specific memory disturbances of subcortical dementias and cortical dementias

In what ways do the specific memory disturbances of subcortical dementias differ from those of cortical dementias? 

Problems with short-term spontaneous recall occur in both types, but strategies to enhance encoding and recognition cuing are mainly helpful in subcortical dementias.

Incidental memory (details not related to the task at hand, such as what the examiner was wearing) is better in subcortical dementias.

Procedural memory (memory involved in learning tasks) is better preserved in cortical dementias.

Remote memory usually shows a temporal gradient in cortical dementias but not in subcortical dementias.
