Cognitive dysfunction and sleep disorders

Show Summary Details


Of all patients over the age of 65 undergoing major surgery, 25% will have a degree of cognitive impairment.

Eleven per cent will have permanent changes.

Up to 73% of elderly surgical patients will have an episode of delirium.

Assessment of mental function is a core skill for all doctors.

Knowledge of the causes and treatment of delirium are necessary.

Evidence for the superiority of any one anaesthetic technique is lacking.

Elderly patients who complain of cognitive decline after surgery should be taken seriously.

Cognitive impairment is associated with poor peri-operative pain control.
