Types of Dementia

dementiaDementia is a chronic or persistent disorder of the mental processes caused by brain disease or injury and marked by memory disorders, personality changes, and impaired reasoning. Dementia usually gets worse over time and how long this takes is different for each person. It is a difficult disorder and one that is very difficult to work with. Alzheimer’s disease is one common form of dementia in the elderly, possibly accounting for up to 70% of dementia in the elderly. In fact, in the US there are at least 5 million individuals with age-related dementias.

Hi, this is Anthony Diaz from Rosa’s Chant’e Adult Care and today I want to help you understand that there are several types of dementia. This is from the Info by Emeritus website and we have used it to help you understand the different types of dementia.

Alzheimer’s Disease

Alzheimer’s causes plaques and tangles in the brain that interrupt the transmission of information between neurons, blocking messages from getting through to their intended target. Alzheimer’s is a progressive disease, meaning that symptoms – primarily memory loss – will almost always get worse.

Vascular Dementia

Vascular dementia is caused by an impaired blood flow to the brain because of blocked arteries or other damage to blood vessels. People often develop vascular dementia after a stroke. Factors that raise your risk of heart disease and stroke – high blood pressure, high cholesterol and smoking – also increase your risk of vascular dementia.

Lewey Body Dementia

With Lewey Body Dementia (LBD), abnormal microscopic protein deposits — called Lewy bodies — develop in regions of your brain involved in thinking and movement. Lewy bodies disrupt the brain’s normal functioning causing it to slowly deteriorate. The effects include a degradation of cognitive functioning, similar to Alzheimer’s disease, or a degradation of motor control, similar to Parkinson’s disease. Because its symptoms mirror other types of dementia, it is frequently misdiagnosed. Other symptoms of LBD include visual hallucinations and delusions.

Parkinson’s Disease

Parkinson’s, like other forms of dementia, is a degenerative disease of the brain. The difference is that symptoms usually begin with physical movements of the body, including trembling and stiffness. Not all people with Parkinson’s will develop cognitive impairment. If they do, this is called dementia resulting from Parkinson’s.

Frontal Lobe

Frontal lobe dementia is a relatively rare form of dementia, caused by a shrinking of the frontal and temporal lobes, areas of the brain that control personality, behavior and language. Like some other forms of rarer types of dementia, frontal lobe is often misdiagnosed. It is a form of dementia that tends to hit people at a younger age – typically anywhere from 40 to 70.

Psychiatric issues and dementia

There is increasing evidence that certain psychiatric issues – particularly depression and bipolar disorder can increase one’s chance of getting dementia. People who develop depression late in life have a greater tendency to get Alzheimer’s disease, while mid-life depression was mostly connected with vascular dementia. With both depression and bipolar disorder, the more episodes of someone being hospitalized with either disorder increased their chance of getting dementia.
