Delirium linked to ‘drastically’ raised risk of new onset dementia

Elderly patients who experience delirium in hospital have a drastic 12-fold increased likelihood of developing dementia, Australian researchers warn.
They say the finding strongly emphasises delirium as a significant risk factor for incident dementia and an episode warrants close monitoring of patients’ cognitive function.
The UNSW Sydney researchers conducted a systematic review and the largest meta-analysis to date on the topic, drawing from six observational studies from developed countries with a combined 901 participants.
Most of the included studies involved hip fracture and cardiac surgery patients aged 65 and older, with follow-up periods that ranged from six months to five years.
