Lewy body disorders are a group of diseases characterized by the presence of Lewy bodies in brain cells. Lewy body disorders include:
- Parkinson’s disease
- Parkinson’s disease with dementia (PDD)
- Dementia with Lewy bodies (DLB)
- Multiple system atrophy (MSA).
In 2006, a group of experts met to consider the similarities between PDD and DLB. They agreed that the symptoms of PDD and DLB are essentially the same, and that both should be considered Lewy body dementias. They decided that if physical symptoms develop a year or more before dementia, a diagnosis of PDD is appropriate. If physical symptoms develop at the same time as or after dementia, then a diagnosis of DLB can be used.
