What is Lewy bodies dementia?

Clinical Features. Neurodegenerative, progressive d/o with  milder physical parkinsonism than parkinson's disease typically. (slowed movements, stiff/rigid muscles & posture, possibly resting tremor). But with early dementia, often with associated psychosis (visual hallucinations/delusional thoughts, excessive sleepiness, depression, anxiety, apathy, & rbd=rem behavior d/o, causing acting-out of dreams in rem sleep.
Lewy body dementia. Second most common cause of dementia after alzheimer's dementia. The is accumulation of abnormal round structures (lewy bodies) in areas of brain responsible for thinking & movements, hence the symptoms my colleague mentioned.
Lewy body dementia. Is one type of dementia characterized by visual hallucinations, fluctuations in alertness and attention and muscle rigidity and tremor. The cause is as yet unknown.
A Type of Dementia. Lewy body dementia (dlb) is a type of dementia where clumps of proteins, called lewy bodies, develop in the brain. It is similar to both alzheimer's and parkinson's diseases. The core symptoms are fluctuating cognition, recurrent visual hallucinations, and motor features of parkinson's disease such as tremors, muscle rigidity, and shuffling gait. Rapid onset and rapid progress are not uncommon.
Second most common. The first symptoms often are visual hallucinations or delusions (fixed false beliefs). At some point there are some motor symptoms similsr to parkinson's disease. There is waxing and waning of symptoms on a daily basis. Falls are common and may be the first symptom noted. Mental rigidity can be a real problem. It is thought to be an illness related to Parkinson's Disease.
Less common dementia. Lbd is either the 2nd or 3rd most common cause of dementia(others are ad and vascular dementia). It is characterized by some features of parkinsons disease, but also includes varying cognition, falls and often vivid visual hallucinations(childrenin the closet a common one). Rarely tremor is present. It is often more rapidly progressive and associated with more behavioral problems.

The essentials. Lewey body dementia is defined by three things, visual hallucinations in the absence of othr drugs, psych diagnoses and parkinson's disease, memory loss and perodic confusion, you can have parkinson symptoms but dont have to. You also usually get behavorial problems and executive problems. The hallucinations tend to be quite vivid and complex. Read more...

Dementia. Dementia with lewy bodies is a leading cause of dementia and people with this have abnormal protein structures in certain parts of the brain. Has similarities with both alzheimer's disease and parkinson's disease. Here's a good starting point for your research: http://sgoti.Ws/tqtza9. Read more...
Rapid Onset. Lewy body dementia is a type of brain disease where both cholinergic and dopaminergic neurons are destroyed causing impairment in cognitive and motor abilities. Lewy bodies, clumps of proteins, can be seen in the brain at autopsy. This dementia usually progresses faster than other dementias and is very sensitive to antipsychotic medications. Often confused with alzheimer's or parkinson's disease. Read more...
Lewy body diagnosis. Best distinguished from the other dementias by the presence of parkinsonian symptoms including rigidity, dysphagia (trouble swallowing), altered gait, and tremor. Also, early on rather than later, psychotic symptoms may be prominent. Unfortunately, these patients do not tolerate antipsychotics very well. Namenda (memantine) - and maybe aricept- can provide relief. Biopsy or new scan sdefinititively diagnos. Read more...

What does Lewy body dementia mean?

Type of dementia. Lewy bodies are a specific type of protein clumps that can accumulate in many places. When they accumulate in the brain, dementia with lewy bodies can occur. It is actually a somewhat common type of neurodegenerative dementia, second only to the more famous alzheimer's disease. If you like, you can look at: www.Lbda.Org for more information. Read more...
Associated with Park. Term is indicative of deposition of Alpha synuclein into nerve cell bodies, which can cause cognitive loss very different from alzheimer's disease. It can be seen prior to, or following parkinson's full blown disease, and although some separate this our from typical parkinson's, it is likely just a sequence variation. There is one approved fda drug, exelon, (rivastigmine) capsule or patch. Read more...

In a nutshell, what is Lewy body dementia?

Three things. It has to include dementia (flucucation in attention and awareness as well as alertness), parkinsonism (not a classical parkinson's) including but not necessarily all of threm - tremors, masking, blinking and shuffling gait, and visual hallucinations. There is abnormal microscopic protein builds up in the brain that disrupts functional brain cells causing them to slowly deterioration of activity. Read more...

Lewy Body risk. We don't have a clear answer for this yet. About 10% of cases are a familial variant and are directly inherited from one parent. The rest may be related to a combination of genes and environmental factors. But the main associated brain change (presence of clumps of alpha-synuclein protein) are also seen in other types of dementia, and so the underlying cause may be similar. Read more...

Who gets dementia with Lewy bodies?

Parkinsons & Lewy. Dementia with lewy bodies can be seen in patients with parkinson's disease, usually appearing about 2 or more yrs following the tremor onset. Alternatively, some patients seem to present first with the dementia and later the parkinsons signs. Both groups are younger than patients with alzheimer's disease, are far more often males, and may have some loose genetic susceptibilities. Read more...

What do Lewy bodies have to do with dementia?

See below. Lewy bodies are accumulated bits of alpha-synuclein protein. They accumulate inside the nuclei of neurons. The areas of the brain where these proteins accumulate will be affected and in turn will affect aspects of functioning that this part of the brain control, either memory or motor control, or both. .

What are the symptoms of dementia with Lewy bodies?

Lewy Body dementia. Lewy bodies are particular types of brain damage, and most often are concentrated in the frontal lobes. Dementia that starts in this brain area is often associated with personality change, motor problems, mood instability, and social inappropriateness, at least initially. Eventually memory loss and global cognitive deficits appear. Read more...
