What is the difference between cortical and subcortical?
In humans, the cortex is where many of the higher-level functions take place (e.g. decision-making and language). ‘Subcortex’ means ‘beneath the cortex’. The subcortex is where we process more primitive functions (e.g. emotion processed in the amygdala).
Is Alzheimer’s cortical or subcortical?
Alzheimer’s disease, the most common of all types of dementia, accounts for between 60 and 80 percent of all cases of dementia and is a cortical dementia. Cortical dementia is the name given to the types of dementia caused by disorders that affect the brain’s cerebral cortex.
What is mixed cortical and subcortical vascular dementia?
Cortical or multi-infarct dementia and subcortical vascular dementia (SVD) are suggested to be the two main forms of VaD. The main clinical features of SVD comprise decreased motor performance, early impairment of attention and executive function with slowing of information processing.
What are cortical regions of the brain?
The cortex can be divided into three functionally distinct areas: sensory, motor, and associative. The main sensory areas of the brain include the primary auditory cortex, primary somatosensory cortex, and primary visual cortex. In general, the two hemispheres receive information from the opposite side of the body.
Is vascular dementia subcortical or cortical?
Vascular dementia is sometimes further classified as cortical or subcortical dementia. Vascular disease produces either focal or diffuse effects on the brain and causes cognitive decline. Focal cerebrovascular disease occurs secondary to thrombotic or embolic vascular occlusions.
What is meant by subcortical?
: of, relating to, involving, or being a part of the brain below the cerebral cortex subcortical lesions.
What is the difference between cortical dementia and subcortical dementia?
Clinical reports suggest that subcortical syndromes (eg, Parkinson’s disease) involve less severe intellectual and memory dysfunction and lack the aphasia, agnosia, and apraxia typical of the cortical dementias (eg, dementia of the Alzheimer type).

What does subcortical mean?
Definition of subcortical. : of, relating to, involving, or being a part of the brain below the cerebral cortex subcortical lesions.
What is subcortical dysfunction?
Subcortical vascular cognitive impairment, characterized by subcortical and executive cognitive dysfunction, is now recognized to be the most common form of vascular cognitive impairment . It arises on the basis of small vessel cerebrovascular disease, in turn, causing lacunar infarcts and ischemic damage to the deep white matter.
What is cortical activity in the brain?
Cortical neurons are the cells of the brain’s largest region, the two hemispheres of the cerebral cortex. Most of the complex activity of the brain enabling thought, perception, and voluntary movement is connected to the activity of these neurons.
What is the cortical region?
cortical area region, area – a part of an animal that has a special function or is supplied by a given artery or nerve; “in the abdominal region” cerebral cortex, cerebral mantle, cortex, pallium – the layer of unmyelinated neurons (the grey matter) forming the cortex of the cerebrum
