CCRN Infectious Encephalopathy Review

Encephalopathy means damage or disease that affects the brain. It happens when there’s been a change in the way your brain works or a change in your body that affects your brain. Those changes lead to an altered mental state, leaving you confused and not acting like you usually do.

Encephalopathy is not a single disease but a group of disorders with several causes. It’s a serious health problem that, without treatment, can cause temporary or permanent brain damage.

It’s easy to confuse encephalopathy with encephalitis. The words sound similar, but they are different conditions. In encephalitis, the brain itself is swollen or inflamed. Encephalopathy, on the other hand, refers to the mental state that can happen because of several types of health problems. But encephalitis can cause encephalopathy.

CCRN Infectious Encephalopathy Review – Causes

Physical Injury

  • When encephalopathy results from repeated trauma, it is called chronic traumatic encephalopathy.
  • Trauma to the head may lead to nerve damage that affects brain function. Chronic traumatic encephalopathy can develop following multiple brain traumas or injuries over time. These may result from a series of accidents or blows to the head.
  • People in the military or who play contact sports may have a higher risk of chronic traumatic encephalopathy.


  • If toxins build up in the blood and reach the brain, they can cause damage. This may result from an underlying condition, infection, or exposure to toxic chemicals.


  • If a person does not receive treatment for high blood pressure, it can lead to swelling in the brain. When this results in a brain injury, it is called hypertensive encephalopathy.

Lack of Oxygen

  • If the brain does not get enough oxygen, a person may experience brain damage. Encephalopathy caused in this way is called hypoxic ischemic encephalopathy.

Vitamin B-1 Deficiency

  • When a person has a vitamin B-1 deficiency, they can develop a type of brain disease called Wernicke encephalopathy.
