Delirium among skilled nursing residents needs to be treated more seriously than it currently is by providers, according to authors of a recent research review.

Researchers found that delirium affects nearly 1 in 5 long-term care residents, but often goes undiagnosed or misdiagnosed in seniors due to the similarities of its symptoms to dementia. 

Residents also were more likely to show delirium symptoms if there was no clock or telephone in their room, the authors found.

Results of the review are in the Journal of the American Osteopathic Association.
