  Lewy body dementia is the second most common type of dementia after Alzheimer’s disease. Protein deposits called Lewy bodies develop in nerve cells in the brain. The protein deposits affect brain regions involved in thinking, memory and movement. This condition is also known as dementia with Lewy bodies. […] Lewy body dementia causes a decline in mental abilities that gradually gets worse over time. People with Lewy body dementia might see things that aren’t there. This is known as visual hallucinations. They also may have changes in alertness and attention. […] People with Lewy body dementia might experience Parkinson’s disease symptoms. These symptoms may include rigid muscles, slow movement, trouble walking and tremors. […] Lewy body dementia symptoms can include: […] Visual hallucinations. Seeing things that aren’t there, known as hallucinations, might be one of the first symptoms of Lewy body dementia. This symptom often occurs regularly. People with Lewy body dementia might see shapes, animals or people that aren’t there. Hallucinations involving sounds, smells or touch are possible.

• #2 Dementia with Lewy bodies – Wikipedia

  https://en.wikipedia.org/wiki/Dementia_with_Lewy_bodies

  Dementia with Lewy bodies (DLB) is a type of dementia characterized by changes in sleep, behavior, cognition, movement, and regulation of automatic bodily functions. Unlike some other dementias, memory loss may not be an early symptom. The disease worsens over time and is usually diagnosed when cognitive impairment interferes with normal daily functioning. […] A presumptive diagnosis can be made if several disease features or biomarkers are present; the diagnostic workup may include blood tests, neuropsychological tests, imaging, and sleep studies. A definitive diagnosis usually requires an autopsy. […] The earliest symptoms are constipation and dizziness from autonomic dysfunction, hyposmia (reduced ability to smell), RBD, anxiety, and depression. RBD may appear years or decades before other symptoms. Memory loss is not always an early symptom.

• #2 What Is Lewy Body Dementia?

  Visual hallucinations, which occur in up to 80% of people with LBD, often early on. […] Individuals with mild symptoms can often function close to normally. As the disease progresses and thinking and movement abilities decline, people with LBD will need more help and may depend on caregivers full time. […] In dementia with Lewy bodies, problems with thinking, unpredictable changes in attention and alertness, and visual hallucinations develop early in relation to movement symptoms, such as slow movement, difficulty walking, and muscle stiffness. […] Dementia with Lewy bodies is often hard to diagnose early because symptoms may at first look like Alzheimer’s or a mental illness such as schizophrenia. […] Although LBD currently cannot be prevented or cured, treatments may be able to help with some of the symptoms. A treatment plan may involve medications, physical and other types of therapy, and counseling. Changes to make the home safer, equipment to make everyday tasks easier, and social support are also important.

  Over time, though, both diagnoses will appear the same. Most people with LBD develop a similar spectrum of problems that include variations in attention and alertness, recurrent visual hallucinations, shuffling gait, tremors, and blank expression, along with various sleep disorders. […] As with Alzheimers disease or Parkinsons disease, the symptoms of Lewy body dementia worsen over time, with intellectual and motor functions deteriorating, typically over several years. […] While patients with LBD lose cognitive function, they are less prone to the short-term memory loss associated with Alzheimers disease. More commonly, they experience greater problems with executive functions of planning, decision-making, and organization, as well as difficulties with visual perception, such as judging and navigating distances.

  Up to 80% of people with Lewy body dementia experience visual hallucinations in the first stage of the condition. This means they see things that are not there. Less commonly, people may hear or smell things that are not there. […] Some people may experience difficulties with movement in the early stages of the condition. However, these changes can be mild and hard to notice, such as a change in handwriting. […] People with Lewy body dementia commonly experience REM sleep behavior disorder (RBD), which can begin several years before other symptoms. […] As Lewy body dementia progresses, a person may experience memory problems. […] A person might develop fluctuating concentration, attention, alertness, and wakefulness. This can change from day to day and even during the same day. […] Their ideas appear disorganized, unclear, or illogical. This feature of the condition also sets it apart from Alzheimers disease and helps doctors distinguish the two conditions.

• #4 Symptoms – Lewy Body Dementia Association

  Each person with LBD is different in terms of which symptoms they have in the beginning. The most common symptoms include changes in thinking, behavior, movement, and sleep. […] Dementia refers to a significant decline in thinking ability. With LBD it affects memory, decision making, problem solving, planning, and abstract or analytical thinking. […] Cognitive fluctuations involve unpredictable changes in concentration, alertness or attention. […] Parkinsons-like symptoms include slowness of movement, rigidity or stiffness, shuffling gait, tremors, and balance problems. […] Behavioral changes include hallucinations, delusions or changes in mood. […] Changes in mood, including depression, anxiety, and apathy, are extremely common in LBD and may significantly affect your quality of life.

[…] While its similar to other dementias, such as Alzheimers disease, LBD can feature a more aggressive cognitive decline and fluctuating symptoms that set it apart. […] Early stage LBD might not be obvious. It can mimic natural age-related cognitive changes. Unlike other dementias, early stage LBD is associated with greater cognitive challenges related to multitasking, as opposed to memory decline. […] Visual hallucinations can also be a common early stage symptom in LBD. […] Early stage changes to your motor function, such as tremors, rigidity, or difficulty walking, are also seen in LBD.

[…] Lewy body dementia (LBD) symptoms may resemble those of other neurological disorders, like Alzheimer’s disease and Parkinson’s disease. Symptoms fluctuate over time and vary from person to person. […] One of the core features of LBD is parkinsonism, which is an umbrella term that refers to brain conditions that cause movement issues including slowed movements (bradykinesia), rigidity or stiffness, and tremors. […] Fluctuating cognitive (mental) function is a relatively specific feature of Lewy body dementia.

  Clinically, whether dementia comes before motor symptoms or soon after (ie, within 1 year) is what distinguishes LBD from PDD, in which the motor symptoms come first. Onset occurs from age 50 to 80. […] Typically, patients with LBD present with cognitive decline with little to no memory impairment and visuospatial processing difficulties, visual hallucinations, autonomic findings, parkinsonian motor fluctuations, or REM sleep behavior disorder (ie, acting out dreams while still asleep). […] Fluctuating delirium-like symptoms are more prevalent in LBD; it is not uncommon for a patient with LBD to have been treated emergently with haloperidol or risperidone for symptoms of delirium only to have their motor symptoms worsen markedly, even to the point of patients being institutionalized unnecessarily.

  Cognitive challenges are a very common non-motor symptom of Parkinsons disease (PD). […] You may have heard of another condition called Dementia with Lewy Bodies (DLB). […] In DLB, the cognitive difficulties and hallucinations develop much sooner in the disease course than in PDD, sometimes even prior to the movement difficulties. […] In both PDD and DLB, symptoms caused by Lewy bodies in the lower brainstem (e.g. constipation, depression, sleep disorders), midbrain (e.g. resting tremor, slowness, stiffness) and cortex (e.g. cognitive difficulties, hallucinations,) can all occur. […] The motor symptoms of slowness, stiffness and walking difficulties can be treated with levodopa. […] Cognitive symptoms in DLB can be treated with the same medications developed for other dementias. These include medications such as donepezil and rivastigmine. Memantine is sometimes used as well.

  Typically, DLB is faster in progression, less responsive to levodopa, and associated with visual hallucinations and fluctuations in the level of alertness. Another distinguishing point is that in DLB, the memory loss precedes the parkinsonism or begins around the same time, whereas in PDD, the parkinsonism typically precedes the memory loss by several years. One symptom seen most commonly with DLB (but also in PD) is REM sleep behavior disorder (RBD), in which there is an absence of the usual paralysis during dream sleep (rapid eye movement REM), resulting in acting out dreams. […] Treatment for Dementia with Lewy Bodies is mainly supportive, meaning medications for cognition, parkinsonism and hallucinations, but these medications tend to provide only modest, and often short-lived, benefit for DLB. Physical therapy can be helpful as well. Avoidance of neuroleptics (antipsychotics) such as haloperidol (Haldol), risperidone (Risperdal), aripiprazole (Abilify), olanzapine (Zyprexa), prochlorperazine (Compazine), metoclopramide (Reglan) is key because of the higher risk of adverse effects in patients with DLB.

  Another characteristic early symptom of LBD is rapid eye movement (REM) sleep behavior disorder. According to the National Library of Medicine, this symptom can appear years before other LBD symptoms develop. […] According to the NIA, the average timeline for LBD to progress from receiving a diagnosis to dying is 5–8 years. However, in some cases, the condition can last up to 20 years. […] LBD progression is typically marked by cognitive function, movement, and mood declines. REM sleep behavior disorder can occur early in the disease but diminishes as other symptoms progress.

  In LBD, sleep disorders are common. Rapid eye movement (REM) sleep behavior disorder is a feature that sets LBD apart from other dementias. […] In late stage dementia, a state of dependency has been reached. You may need full or partial assistance during daily life because symptoms impair your physical and mental function. […] In LBD, behavioral symptoms become worse as the condition progresses. […] One of the most defining characteristics of LBD is the presence of fluctuating cognition. Unlike in other dementias, cognitive changes in LBD can come and go, occurring through all its stages. […] LBD is often more aggressive than other types of dementia. On average, the time between diagnosis and end of life is 5 to 8 years. […] As in all dementia, late stage LBD involves significant loss of independent function, behavioral changes, and major memory deficits. […] Theres no cure for this condition, but even during its late stage, cognitive symptoms may abruptly go into remission due to whats known as fluctuating cognition.

  Lewy body dementia (LBD) is a brain disorder that can lead to problems with thinking, movement, behavior, and mood. Visual hallucinations, or seeing things that are not there, are a common symptom, and tend to happen early on. […] It is a progressive disease, meaning symptoms start slowly and worsen over time. […] People with LBD live on average five to eight years but may live as few as two years or as long as 20 years from the time of diagnosis to death. How fast symptoms develop and change varies depending on the persons overall health, age, and level of symptoms. […] The most common symptoms of LBD include changes in thinking abilities, movement, sleep, and behavior. The degree of symptoms can vary widely and people with LBD may not have every symptom. Common symptoms include: Trouble with attention, planning, multitasking, problem-solving, and reasoning. Memory problems are also common but may not be noticeable early on.

  https://www.alzheimers.org.uk/about-dementia/types-dementia/dementia-with-lewy-bodies

  Dementia with Lewy bodies (DLB) is a type of dementia caused by Lewy bodies, which are clumps of protein in the cells of the brain. […] Lewy bodies cause a range of symptoms, some of which are shared by Alzheimers disease and some by Parkinsons disease. For this reason, DLB is often wrongly diagnosed. […] In DLB, the symptoms of dementia begin before or around the same time as the person develops problems with movement. […] Many people with DLB also have a build-up of other proteins that cause Alzheimers disease. This is common in people over about 80 years old. For people with both DLB and Alzheimers, dementia symptoms are often more severe and progress more quickly. […] Around 5% of people with a diagnosis of dementia are recorded as having DLB, but there is good evidence that the condition is under-diagnosed. Scientists think DLB may account for up to 20% of all dementia. […] Dementia with Lewy bodies affects men and women roughly equally. As with most other types of dementia, DLB becomes increasingly common over the age of 65. It can also affect people younger than this.

  https://www.alzheimers.org.uk/about-dementia/types-dementia/dementia-with-lewy-bodies-symptoms

  Symptoms of DLB include having difficulties staying focused, experiencing delusions, and having problems with movement and sleep. […] The way someone is affected by DLB will depend partly on where the Lewy bodies are in the brain: Lewy bodies at the base of the brain are closely linked to problems with movement. These are the main feature of Parkinsons disease. Lewy bodies in the outer layers of the brain are linked to problems with mental abilities, which is a feature of DLB and other types of dementia. […] When DLB starts to affect someone, early symptoms may not cause too many difficulties. Gradually though, these get worse and cause problems with everyday living. […] Both DLB and Alzheimers disease can cause problems with staying focused, difficulties with making decisions, memory loss, problems with the way the person sees things around them.

  In contrast, in LBD, difficulties with problem-solving or spatial problems tend to arise before memory difficulties. But any of these symptoms can occur first or in combination, and they may fluctuate. Perception is often affected, which can manifest as visual hallucinations. Delusions (false beliefs) are also common as the disease progresses. […] „Whereas hallucinations and delusions are common late in the course of Alzheimer’s disease, visual hallucinations often arise early in LBD. For example, a person with LBD might see people or animals that aren’t there,” he says. „Such hallucinations are only rarely perceived as threatening.” […] People with LBD may act out their dreams. Known as REM sleep behavioral disorder, this problem often arises even before thinking problems start. […] People with Lewy body dementia often move slowly and stiffly, developing tremors and gait changes and becoming prone to falls.

  Lewy body dementia is a progressive, complex and challenging condition which is thought to account for 10- 15% of all those with dementia. Around 10% of younger people with dementia have dementia with Lewy bodies. In the early stages it is often mistaken for Alzheimer’s disease and can be diagnosed wrongly. […] Lewy body dementia includes two subtypes; dementia with Lewy bodies and Parkinson’s dementia. It particularly affects the person’s ability to think and move and can cause hallucinations, fluctuations in alertness and sleep disturbances which can be extremely distressing for the person and their family. […] The main difference between the two types of Lewy body dementia is when certain symptoms first occur: Dementia with Lewy bodies – changes in thinking, visual perception (cognitive symptoms) and sleep may be experienced first and difficulty with movement (Parkinsonian symptoms) – occur at the same time or later.

  Dementia with Lewy bodies is the third most common disease that causes dementia. […] The word dementia is used to describe a group of symptoms. These include: memory loss, confusion, changes to communication, mood and behaviour. These symptoms affect day-to-day life. […] For every 100 people who have dementia, about 10-15 will have dementia with Lewy bodies. […] As DLB progresses, Lewy bodies build up and this accumulation is accompanied by damage to nerve cells. This damage affects the way that our brain cells communicate. […] Dementia with Lewy bodies is closely related to Parkinson’s disease (PD). […] Dementia with Lewy bodies and Parkinson’s disease dementia can affect people in very similar ways, and people will receive a diagnosis of one or the other dependent on the timing of certain symptoms.

  Fluctuating cognitive function is a relatively specific feature of dementia with Lewy bodies. […] Memory is impaired, but the impairment appears to result more from deficits in alertness and attention than in memory acquisition; thus, short-term recall is affected less than digit span memory (ability to repeat 7 digits forward and 5 backward). […] Visual hallucinations are common and often threatening, unlike the benign hallucinations of Parkinson disease. […] Autonomic dysfunction is common, and unexplained syncope may result. […] Sleep problems are common. Many patients have rapid eye movement (REM) sleep behavior disorder, a parasomnia characterized by vivid dreams without the usual physiologic paralysis of skeletal muscles during REM sleep. […] In Parkinson disease dementia (unlike in dementia with Lewy bodies), cognitive impairment that leads to dementia typically begins 10 to 15 years after the onset of motor symptoms. […] In dementia with Lewy bodies, traditional antipsychotics, even at very low doses, tend to acutely worsen extrapyramidal symptoms and are best avoided.

  Dementia with Lewy bodies (DLB) is one of the most common types of degenerative dementias, second to Alzheimer disease (AD). In addition to dementia, distinctive clinical features include visual hallucinations, parkinsonism, cognitive fluctuations, rapid eye movement (REM) sleep behavior disorder (RBD), dysautonomia, and neuroleptic sensitivity. […] There is increasing consensus that DLB is a clinically distinct disorder, distinguished by early onset of dementia and more rapid progression. By contrast, dementia occurs much later in patients with PDD, sometimes as much as 10 years after the onset of Parkinson disease (PD). […] DLB is comparatively underrecognized and harbors a poorer prognosis, with an average disease duration of five to eight years from symptom onset. […] Clinical diagnostic criteria for DLB are continually being refined to improve specificity and sensitivity. Appropriate diagnosis is critical in order to provide the best treatment in regard to maximizing efficacy and limiting adverse effects.
