Dementia with Lewy bodies (DLB) is a specific type of dementia with symptoms quite similar to Parkinson's disease and Alzheimer's disease. Almost 10% of all dementia cases are DLB. Some experts refer to the same condition by other names – the list includes Lewy body variant of Alzheimer's disease, LBD, cortical Lewy body dementia, and senile dementia of Lewy body type. It is worth mentioning that Lewy body dementia symptoms are quite confusing and are usually mistakenly diagnosed as several other conditions. It is therefore important to know the symptomsto identify the most suitable treatment option.
Some of the most common LBD signs and symptom include the following:
It is worth mentioning that as LBD affects that part of your nervous system that deals with automatic bodily functions, such as the heart, muscles, and glands, you may experience the following symptoms as well.
If you think you or someone in your family has these early symptoms of dementia, it is a good idea to discuss it with your general physician. Your GP will perform certain tests to identify the causes behind Lewy body dementia symptoms to determine a plan of action.
Just like other types of dementia, it is hard to pinpoint a test that will help make a decision about your condition. It is more of a "clinical" diagnosis, which means the doctor will use his/her knowledge to determine the cause of DLB in your case.
It is important to mention that some experts believe that DLB and Parkinson's disease dementia are two different names of the same condition caused mainly due to brain's inability to process the protein alpha-synuclein. However, other experts think they are two different disorders. It's DLB if the earliest dementia symptoms point to DLB and both movement symptoms as well as dementia symptoms show at the same time.
It's Parkinson's disease when movement symptoms appear first and dementia symptoms don't appear at the same time – it usually takes a year or so for dementia symptoms to appear. Delusions and hallucinations are more common in DLB than in Alzheimer's disease. Similarly, REM sleep disorder, dizziness, blood pressure drop, urinary incontinence, and falls are more common in early LBD than in Alzheimer's disease.
It is not easy to take care of someone suffering from LBD, but knowledge about certain things will definitely help make it easier for you to manage LBD symptoms better. The good thing is that patients can stay at home with their families, but they will always require close supervision because there are always chances of a fall.
