In brief: Definition

In most kinds of dementia, autopsy reveals widespread degeneration in the cerebral cortex - such as the plaques and tangles which are the hallmark of alzheimer's disease.
Alzheimer's disease and frontotemporal dementia are therefore sometimes classed as "cortical dementias." in other kinds of dementia, there is targeted damage to regions lying under the cortex, giving rise to sub cortical dementia.

In brief: One of 2 types

One way to divide the kinds of dementia that exist is by looking at what part of the brain is effected.
So there can de dementias that affect the cortex like alzheimers disease as well as those that affect the subcortical areas of the brain like huntington's disease. This way of classifying dementia is less used now. We tend to talk about specific illnesses such as alzheimers or lewy body etc.

In brief: An older term

Subcortical dementia is not a distinct type of dementia.
There is considerable overlap between the traditional "cortical" and "subcortical" dementias, and emphasis should be placed on identifying the precise cause of dementia, not categorizing the dementia as cortical or subcortical. See: http://goo.Gl/vxxzc for a nice review of the topic.
