what is the difference between vascular dementia and lewy body dementia?

Regardless of the initial symptom, over time all three presentations of LBD will develop very similar cognitive, physical, sleep and behavioral features, all caused by the presence of Lewy bodies throughout the brain. Vascular dementia is caused by a series of small strokes that deprive the brain of vital oxygen.

Alzheimer's Disease: What is the Difference? Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Alzheimer's is the most common cause of dementia. Alzheimer's is a specific disease.

About 10% of Lewy body dementia cases appear to be tied to heredity, where the person inherits the disease from a parent. When someone has had Lewy body dementia or Parkinson's disease, his or her family members have a higher risk of developing Lewy body dementia.

Having high blood pressure is a risk factor for vascular dementia. If you can lower your blood pressure through lifestyle changes and medicines, you can reduce your risk. Vascular dementia is most commonly caused by the effects of a stroke.

Frontotemporal dementia (FTD) and dementia with Lewy bodies (DLB) are distinct neurodegenerative syndromes. FTD is characterized by a gradual and progressive change in behavior and personality, executive dysfunction, and language impairment. Consensus criteria for the diagnosis of FTD exist.

Dementia is an umbrella term used to describe a range of progressive neurological disorders, that is, conditions affecting the brain. There are over 200 subtypes of dementia, but the five most common are: Alzheimer's disease, vascular dementia, dementia with Lewy bodies, frontotemporal dementia and mixed dementia.

Treatment can help prevent further damage to the brain in people with vascular dementia and may slow down its progression. But there's currently no cure for the condition or a way to reverse the damage that's already happened.

Inheritance Pattern When dementia with Lewy bodies is caused by SNCA or SNCB gene mutations, it is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In these cases, an affected person usually has one parent with the condition.

On average, people with vascular dementia live for around five years after symptoms begin, less than the average for Alzheimer's disease. In many cases, the person's death will be caused by a stroke or heart attack.

People often mistakenly think that dementia is just another name for Alzheimer's disease, and that dementia and senility are one and the same. But dementia is actually a variety of medical conditions and illnesses that impair a person's cognitive health. Alzheimer's disease is one type of dementia.

After the symptoms of dementia with Lewy bodies begin, people live on average for six to twelve years. However, each person will experience dementia with Lewy bodies differently.

Visual hallucinations are one of the hallmark symptoms in Lewy body dementia (LBD) and often occur early in the illness. In other dementias, delusions are more common than hallucinations, which occur well into the disease cycle, if at all, and are less often visual.

Dementia with Lewy bodies is often hard to diagnose because its early symptoms may resemble those of Alzheimer's or a psychiatric illness. As a result, it is often misdiagnosed or missed altogether. As additional symptoms appear, it is often easier to make an accurate diagnosis.

If blood flow is only interrupted for short time, it's known as a transient ischemic attack (TIA), or “ministroke.” TIA symptoms lasts less than 24 hours before disappearing. Both ischemic stroke and TIA are associated with vascular dementia. Vascular dementia is the second most common form of dementia.

Dementia caregivers describe knowing what to expect as an unmet need and many are unaware that dementia can be a terminal condition. Dementia with Lewy bodies (DLB) is a common neurodegenerative dementia with unique features which may affect the end of life (EOL).

Lewy body dementia (LBD) is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and mood.
