Surgery

Clinical applications for perioperative cognitive assessment.

In the perioperative setting, postoperative cognitive dysfunction (POCD) occurs in up to 53% of patients over 65 years of age¹ and in patients with moderate to severe cases, decline in cognitive function can be substantial and long term².

Delirium is a disease state that develops as a side effect of illness, pharmaceutical agent, or other complication, and is dependent upon interactions of a complex set of risk factors.

Cogstate has been involved in research in delirium and post operative cognitive dysfunction for more than 12 years, and the Cognigram solution has been shown as an effective tool for measuring cognitive change:

detected significantly larger number of patients with worsened results than the conventional tests (p>0.05)³

may detect change in a greater proportion of patients 6 days after CABG surgery than conventional neuropsychological tests.4
