In a consortium of international scientists met in Newcastle, England, to agree on clinical and diagnostic criteria for DLB [1]. A second report [2] published in somewhat modified the criteria. In order to improve diagnostic reliability and sensitivity, the consortium met again in and agreed to significant amendments [3] in the guidelines.
Recommendations for treatment were made and the concept of DLB being part of a spectrum of alpha-synuclein pathologies was postulated. Finally in the consortium published new guidelines with revised criteria [4]. Although he had loyally served Germany in World War I in charge of field hospitals in France, Russia, and Turkey, he was later persecuted by his native country for being a Jewish person.
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. LBD can also occur alongside other forms of dementia. Talking to both the patient and family members or caregivers can help doctors make a diagnosis.
It is important to tell the doctor about any symptoms involving thinking, movement, sleep, behavior, or mood. 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. A skilled care team can suggest ways to improve quality of life for both people with LBD and their caregivers.
A neurologist should be part of the care team and can help patients and their families work with other types of professionals. Support groups can also be a valuable resource for people with LBD and their caregivers to share experiences and tips with others in the same situation.
Nonprofit organizations and community organizations may provide online or in-person support groups. If you are concerned about symptoms of LBD, talk with your doctor or contact a dementia or movement disorders clinic at an academic medical center to find a specialist. If you or someone you know has been recently diagnosed, explore the resources on this website and linked below to find out more about the disease, care, support, and research.
Researchers are working to better understand LBD and related disorders to treat and prevent these diseases. Consider joining the effort: Researchers need volunteers with and without LBD for clinical trials and studies.

Lewy body dementia LBD is a type of progressive dementia that leads to a decline in thinking, reasoning and independent function because of abnormal microscopic deposits that damage brain cells over time. About Causes and risks Symptoms Treatment Diagnosis.
Most experts estimate that Lewy body dementia is the third most common cause of dementia after Alzheimer's disease and vascular dementia , accounting for 5 to 10 percent of cases.
The hallmark brain abnormalities linked to Lewy body dementia are named after Frederich H. Lewy, M. Alois Alzheimer's laboratory during the early s. Alpha-synuclein protein, the chief component of Lewy bodies, is found widely in the brain, but its normal function isn't yet known. Lewy bodies are also found in other brain disorders, including Alzheimer's disease and Parkinson's disease dementia.
Many people with Parkinson's eventually develop problems with thinking and reasoning, and many people with Lewy body dementia experience movement symptoms, such as hunched posture, rigid muscles, a shuffling walk and trouble initiating movement. This overlap in symptoms and other evidence suggest that Lewy body dementia, Parkinson's disease and Parkinson's disease dementia may be linked to the same underlying abnormalities in how the brain processes the protein alpha-synuclein. Many people with both Lewy body dementia and Parkinson's dementia also have plaques and tangles — hallmark brain changes linked to Alzheimer's disease.

Since Lewy bodies tend to coexist with Alzheimer's brain changes , it may sometimes be hard to distinguish Lewy body dementia from Alzheimer's disease, especially in the early stages. Key differences between Alzheimer's and Lewy body dementia Memory loss tends to be a more prominent symptom in early Alzheimer's than in early Lewy body dementia, although advanced Lewy body dementia may cause memory problems in addition to its more typical effects on judgment, planning and visual perception.
