Dementia with Lewy bodies is a type of dementia that is similar to both Alzheimer's disease and Parkinson's disease but studies on long-term treatments are lacking. A new study from Karolinska Institutet in Sweden, published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association , highlights the potential cognitive benefits of cholinesterase inhibitor treatment. Lewy body disease, which includes dementia with Lewy bodies (DLB) and Parkinson's disease with and without dementia, is the second most common neurodegenerative disorder, following Alzheimer's disease.
DLB accounts for approximately 10–15 per cent of dementia cases and is characterised by changes in sleep, behaviour, cognition, movement, and regulation of automatic bodily functions. There are currently no approved treatments for DLB, so doctors often use drugs for Alzheimer's disease, such as cholinesterase inhibitors and memantine, for symptom relief. However, the effectiveness of these treatments remains uncertain due to inconsistent trial results and limited long-term data.
" Hong Xu, assistant professor at the Department of Neurobiology, Care Sciences and Society, Karolinska Institutet and first author of the paper In the current study, researchers have examined the long-term effects of cholinesterase inhibitors (ChEIs) and memantine compared with no treatment for up to ten years in 1,095 patients with DLB. They found that ChEIs may slow down cognitive decline over five years compared to memantine .
