Lewy body dementia takes its name from Lewy bodies, which are abnormal structures found in some nerve cells in the brain of people with the condition. This type of dementia may result in a wide range of symptoms, such as visual hallucinations, tremor, acute confusion, and memory loss. Lewy body dementia is the second most common type of degenerative dementia seen in the elderly. There is no cure; however, treatment with antiparkinsonian drugs, cholinesterase inhibitors, or a combination of these medications may help ease symptoms.
