40-Page Free Book on Lewy Body Dementia

Cover of Lewy Body Dementia Book


Free LBD book, from the U.S. government’s NIH, with insights into caregiving, movement, sleep & behavior. More than 1 million American adults have Lewy Body dementia. Learn about this common cousin of Alzheimer’s & Parkinson’s.

More than 1 million American adults are affected by Lewy Body dementia (LBD).
An important publication from the National Institutes of Health (NIH) describes LBD — a brain disorder that can affect cognition, movement, sleep, and behavior. This booklet offers practical advice for people with the disease and caregivers.

The free book, Lewy Body Dementia: Information for Patients, Families, and Professionals, will help you find out more about:

  • Types of LBD: dementia with Lewy Bodies and Parkinson’s disease dementia
  • Causes and risk factors
  • Symptoms, diagnosis, and treatment
  • Caregiving and living with LBD

The 40-page booklet is jointly published by the National Institute on Aging (NIA) and the National Institute of Neurological Disorders and Stroke, both part of NIH.

Get your copy of the book at no charge. A free link appears below.

More on LBD

What is Dementia With Lewy Bodies?

Dementia with Lewy bodies (DLB) is one of the most common types of progressive dementia. The central feature of DLB is progressive cognitive decline, combined with three additional defining features:  (1) pronounced “fluctuations” in alertness and attention, such as frequent drowsiness, lethargy, lengthy periods of time spent staring into space, or disorganized speech; (2) recurrent visual hallucinations,  and (3) parkinsonian motor symptoms, such as rigidity and the loss of spontaneous movement.   People may also suffer from depression.  The symptoms of DLB are caused by the build-up of Lewy bodies – accumulated bits of alpha-synuclein protein — inside the nuclei of neurons in areas of the brain that control particular aspects of memory and motor control.  Researchers don’t know exactly why alpha-synuclein accumulates into Lewy bodies or how Lewy bodies cause the symptoms of DLB, but they do know that alpha-synuclein accumulation is also linked to Parkinson’s disease, multiple system atrophy, and several other disorders, which are referred to as the “synucleinopathies.” The similarity of symptoms between DLB and Parkinson’s disease, and between DLB and Alzheimer’s disease, can often make it difficult for a doctor to make a definitive diagnosis. In addition, Lewy bodies are often also found in the brains of people with Parkinson’s and Alzheimer’s diseases.  These findings suggest that either DLB is related to these other causes of dementia or that an individual can have both diseases at the same time.  DLB usually occurs sporadically, in people with no known family history of the disease. However, rare familial cases have occasionally been reported.

Is there any treatment?

There is no cure for DLB.  Treatments are aimed at controlling the cognitive, psychiatric, and motor symptoms of the disorder. Acetylcholinesterase inhibitors, such as donepezil and rivastigmine, are primarily used to treat the cognitive symptoms of DLB, but they may also be of some benefit in reducing the psychiatric and motor symptoms.  Doctors tend to avoid prescribing antipsychotics for hallucinatory symptoms of DLB because of the risk that neuroleptic sensitivity could worsen the motor symptoms.  Some individuals with DLB may benefit from the use of levodopa for their rigidity and loss of spontaneous movement.

What is the prognosis?

Like Alzheimer’s disease and Parkinson’s disease, DLB is a neurodegenerative disorder that results in progressive intellectual and functional deterioration.  There are no known therapies to stop or slow the progression of DLB.  Average survival after the time of diagnosis is similar to that in Alzheimer’s disease, about 8 years, with progressively increasing disability. 

What research is being done?

The National Institute of Neurological Disorders and Stroke (NINDS) conducts research related to DLB in laboratories at the NIH and also supports additional research through grants to major medical institutions across the country. Much of this research focuses on searching for the genetic roots of DLB, exploring the molecular mechanisms of alpha-synuclein accumulation, and discovering how Lewy bodies cause the particular symptoms of DLB and the other synucleinopathies. The goal of NINDS research is to find better ways to prevent, treat, and ultimately cure disorders such as DLB.

This site was inspired by my Mom’s autoimmune dementia.

It is a place where we separate out the wheat from the chaffe, the important articles & videos from each week’s river of news. With a new post on Alzheimer’s or dementia appearing on the internet every 7 minutes, the site’s focus on the best information has been a help to many over the past 15 years. Thanks to our many subscribers for your supportive feedback.

The site is dedicated to all those preserving the dignity of the community of people living with dementia.
