Dementia with Lewy Bodies vs. Parkinson's Dementia: Same or Different?

Parkinson's disease dementia and dementia with Lewy bodies... Are they the same thing? I remember the first time I wondered about this question:  Were there two different disorders with two different names, or one disorder that could be called both PDD and DLB? This question came about as I was reading through the medical history of a patient and noticed that in some places in his chart he had a diagnosis of PDD, and in other areas of his records, his diagnosis was listed as DLB. In asking other professionals, I discovered that opinions varied about the answer to my question. I found that some physicians felt strongly that PDD and DLB were really variations of the same disorder, while others debated if the two conditions were significantly different from each other. I sought further clarification by researching the diagnostic guidelines on these disorders, and found that currently agreed upon criteria is different for PDD as compared to DLB, although they're both considered to be a type of Lewy body dementia. In other words, PDD and DLB are classified as separate diagnoses. They have sets of symptoms that are similar to each other, yet they also have some specific differences from each other.
