Lewy Body Dementia and Pick's Disease Mnemonic

Here's a quick mnemonic for some of the distinguishing features of Lewy Body Dementia and Pick's Disease:

Lewy Body Dementia has "halLEWYcinations" (hallucinations)
Pick's Disease has Personality changes

Pick's Disease is also known as frontotemporal dementia, because it affects the frontal and temporal lobes (obviously). But if you remember the mnemonic, you can easily remember it affects the frontal lobe because of the change in personality.
