Dementia with Lewy Body happens when abnormal structures, called Lewy bodies, build up in certain areas of the brain. There are important distinctions to note in the difference between Alzheimer’s and DLB. Alzheimer's affects the brain's ability to store new information in the form of memories, while Lewy body dementia targets a different set of cognitive functions - specifically problem-solving and reasoning.

It can include both Parkinson’s disease dementia (PDD) in which Parkinson’s disease is first diagnosed and symptoms of LBD appear later) and Dementia with Lewy bodies (DLB) which starts with dementia and is often misdiagnosed as Alzheimer’s disease, but may include Parkinson-like symptoms at the time of diagnosis or later. Over time, people with dementia with Lewy bodies or Parkinson's disease dementia may develop similar symptoms.

Symptoms: LBD includes visual hallucinations, delusions, paranoia, tremors or shaking, apathy, quick changes in mood, and frequent variations in cognitive ability, attention or alertness. There are also changes in walking or movement, as well as a sleep disorder called REM sleep behavior disorder, in which people physically act out their dreams. *LBD patients may also have a severe sensitivity to medications prescribed for hallucinations.

LBD affect not only the individual diagnosed with the illness, but also caregivers, families, and friends. The Life Care Manager can help families overcome these challenges.
