Susan Williams, wife of the late actor and comedian Robin Williams, called Lewy body disease "the terrorist inside my husband's brain."
In the US it the second-leading cause of dementia after Alzheimer disease, which is frequently is misdiagnosed as Alzheimer or Parkinson disease.
According to research reported online Wednesday, June 7, in Neurology, the international Dementia with Lewy Bodies Consortium issued new guidelines about diagnosing and treating the disease and called for more clinical trials into the illness.
"The updated clinical criteria and associated biomarkers hopefully will lead to earlier and more accurate diagnosis, and that is key to helping patients confront this challenging illness and maximize their quality of life," says Bradley Boeve MD, a co-author of the paper and a neurologist at Mayo Clinic, which sponsored an international dementia with Lewy bodies conference in December 2015.
Yesterday's report is the first publication to come out of the conference. The previous consensus guidelines were published in 2005. By weighting clinical signs and biomarkers, the new recommendations give detailed guidance to help diagnose dementia with Lewy bodies. Its' symptoms include:
"Despite dementia with Lewy bodies being relatively common, some physicians and many in the public still have never heard of this disorder," Dr Boeve says.
Protein deposits -- named after Frederick Lewy who discovered them -- develop in brain cells and are believed to cause some to die and others to malfunction. The new guidelines give treatment recommendations, such as using holinesterase inhibitors to try to improve cognition by triggering nerve impulses from one brain cell to the next.
"Previously, there has been little agreement on the optimal medication and non-medication approaches for patients and their families," Dr Boeve notes.
The report has more than 60 contributors, worldwide experts in their field.
The National Institute on Aging and National Institute of Neurological Disorders and Stroke of the National Institutes of Health supported this work, among others.
