Lewy Body Dementia, also known as LBD, is a progressive brain disorder that affects thinking, movement, behavior, and sleep. While LBD is a commonly used term, there are other synonyms for this condition, such as dementia with Lewy bodies (DLB), cortical Lewy body disease (CLBD), and diffuse Lewy body disease (DLBD). These terms describe the same disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to impairments in cognitive and motor functions. The different names for Lewy Body Dementia reflect its various clinical features and brain regions affected. Regardless of the name used, individuals diagnosed with LBD and their families face significant challenges in managing the disease and maintaining quality of life.
