Difference Between Cortical Dementia and Subcortical Dementia

The significant difference between cortical and subcortical dementia indicates that cortical dementia is a kind of dementia influencing the brain's cerebral cortex. In contrast, subcortical dementia is a kind of dementia affecting the subcortex region of the brain, which consist of white matter and has to do with many areas, which include the striatum, substantia nigra, and globus pallidus. Dementia is a disorder that leads to the inadequate capacity to recall, guess, or make determinations. It can influence various areas of the brain. Dementia can be classified into two kinds, cortical or subcortical dementia. Cortical dementia affects the cerebral cortex part of the brain, which is higher than the subcortex, whereas subcortex dementia influences the subcortex part of the brain.

What is Cortical Dementia?

Cortical dementia often explains dementia influencing the cerebral cortex of the brain. The cerebral cortex is the brain’s external layer and possesses gray substances. It operates different essential processes. There are various kinds of cortical dementia, including Alzheimer’s ailments, Lewy body dementia, posterior cortical atrophy, frontotemporal lobe dementia, and creutzfeldt-jakob diseases. The indications of cortical dementia may have to do with modifications in character, disposition, and demeanor, loss of memory, confusion, alterations in determination, disorientation, incapability to identify familiar faces or known objects, difficulties in swallowing and walking, problems in speaking, and language, and emotional problems. However, cortical dementia can be triggered by the creation of proteins described as beta-amyloid in the brain, a varying quantity of tau protein, and another type of protein described as TDP-43 in the brain as a result of gene transformations. Cortical dementia can be diagnosed via physical tests, blood exams, genetic examinations, family records, and cerebrospinal fluid samples. Also, the treatment for cortical dementia can be performed by providing drugs such as aducanumab, anti-anxiety mechanisms, occupational therapy, speech therapy, and physical therapy.

What is Subcortical Dementia?

Subcortical dementia results from harm to the subcortex area of the brain. There are various subcortical dementias related to Huntington’s ailments, Parkinson’s ailment, and AIDs dementia complications. The indications of subcortical dementia may have to do with problems performing specific assignments, problems in adhering to commands, forgetting present and previous occurrences, language problems, getting lost more often, misplacing items, modification to sleep methods, losing attraction in people, preliminary determination, fantasies, hallucinations, alterations in the disposition, and incapability to perceive threats. However, subcortical dementia is triggered by tiny vessel ailments that decrease blood discharge to the brain and harm the axons or white substance. Subcortical dementia can be diagnosed using physical tests, medical records, blood examinations, cognitive ability exams, and imagery exams such as MRIs and CT scans. Also, subcortical dementia can be treated using drugs to manage increased blood pressure, increased cholesterol, an anticoagulant or reduced dose of aspirin to decrease the threat of blood clumps, and therapies that have to do with cognitive incitation therapy, cognitive rehabilitation, creative arts therapy, occupational and music therapy.

Cortical dementia is a kind of dementia that influences the brain’s cerebral cortex. In contrast, subcortical dementia is a kind of dementia that affects the subcortex region of the brain, which consist of white substances and has to do with many areas which, include globus pallidus, striatum, and substantia nigra. However, this is the primary difference between cortical and subcortical dementia. Also, cortical dementia harms the neural cell bodies and dendrites, described as gray substances and axon terminals. On the contrary, subcortical dementia breaks the axons or white substance.
