How is postoperative cognitive dysfunction diagnosed?

How is postoperative cognitive dysfunction diagnosed?

POCD is measured using a series of tests called neurocognitive tests. These tests look at several important brain areas involved in learning and memory.

What are the symptoms of postoperative cognitive dysfunction?

Cognitive disorders include disorientation in space and time, language difficulties, impairment in learning and memory. The emotional disorders may be apparent, with intermittent and unstable symptoms of anxiety, fear, irritability, anger and depression. The postoperative delirium often has a changing intensity.
