The Cognitive Effects of “Going Under”

If you’ve ever had to have surgery for any reason, you’ll know that it comes with various risks. These risks are discussed before surgery is undergone and can include things like pain, infection, and some less likely, but more serious complications. These are all standard procedure when it comes to operations.

 

What isn’t discussed as readily is the impact and risk of the general anesthetic required to carry out the surgery. That’s why today, we’re shining the spotlight on the effects of general anesthesia on cognitive function, and offering up ways to mitigate them.

 

POCD

General anesthesia is a crucial part of the healthcare system that has been in widespread use for well over a century. Nevertheless, its impact on our brains still isn’t entirely understood.

 

Growing bodies of research have revealed that after general anesthesia has worn off, there are often significant impacts on one or more of the following factors:

 

  • Cognitive functioning

  • Memory

  • Concentration and focus

  • Executive function

  • Psychomotor speed

  • Visuospatial ability

 

in both the long and short term. POCD, or postoperative cognitive decline is the name given to this phenomenon.

 

So, what are the risk factors?

Well, studies suggest that those most at risk are older adults. As we age, there is a natural degenerative decline within the brain. On top of that, older adults in an ever-aging population are more likely to require surgical intervention for age-related health concerns. The risk of any type of complication from surgery increases as we age, including that of developing cognitive issues resulting from general anesthesia.

 

Although it’s been longer established that the elderly can suffer the effects of anesthesia- induced cognitive decline, more recent research has pointed to notable impacts on those in middle age and children whose brains are still developing, too.

 

Some other factors that can potentially increase the incidence of POCD include existing conditions such as cardiac issues and vascular disease, among others.

 

What actually causes POCD?

Research is still ongoing as to the exact cause of postoperative cognitive decline. What we know so far points to increased levels of neuroinflammation as a result of surgery and anesthesia.

 

Risk mitigation

Of course, surgeries are usually life-changing and essential procedures designed to treat and resolve a variety of health concerns. With that said, here are some of the ways that you prepare your brain to be in optimum condition both before and after surgery.

  • Avoid inflammatory foods and include plenty of brain-healthy foods

  • Exercise regularly

  • Focus on new learning to keep your brain stimulated

  • Prioritize restful sleep

  • Be socially active and connect with others

  • Practice mindfulness, meditation, or yoga and focus on reducing stress.
