How does dementia with lewy bodies typically progress?

LBD is a type of memory disorder that causes a progressive decline in mental faculty and sadly, it will get worse. Hallucinations and decline or changes in alertness or attentiveness are common symptoms and get worse as the dementia progresses. It often leads into more serious conditions like Parkinson's disease which has symptoms like walking difficulty, stiffness, limb rigidity and tremors. Unfortunately there is no known cure.
