Describe neurocognitive disorders: difference between delirium/dementia

Delirium is a disturbance in attention and awareness and change in cognition that develops

rapidly over a short period. Differentiating delirium from dementia can be a complicated

process, but failure to recognize delirium and the cause can delay appropriate treatments

causing severe consequences. It is also the most frequent complication of hospitalization in

older adults. It is associated with increased morbidity and can have lasting long-term results,

such as permanent cognitive decline.
