About the Symptom
A disorder of consciousness, also known as "impaired consciousness", is when a person's ability to be awake and aware is impaired. After brain injury, a patient may recover consciousness completely or may not recover completely. If the patient does not recover completely and has problems with being awake and aware, this is considered a "disorder of consciousness".
When to see a doctor
Seek professional care if you experience any of the following symptoms
Brain not functioning / Brain fog
Possible Causes
Generally, Brain fog can be related to:
Acute disseminated encephalomyelitis involves widespread inflammation of the brain and spinal cord, resulting in damage to nerve fibers and their protective linings. It is a result of inflammation that occurs after after an infection or immunization. While it can affect anyone it is more common in children.
Hydrocephalus refers to the abnormal flow of a naturally-occuring brain fluid (cerebrospinal fluid, or CSF) within natural brain cavities (ventricles), causing fluid buildup. This leads to swelling of the ventricles and increased pressure in the brain, which, if untreated, can cause brain damage in pressurized brain regions. Hydrocephalus is most common in infants and older adults. It has a number of causes, including certain genetic conditions, birth defects of the brain, as well as tumors, stroke, head trauma, or brain infections (such as meningitis). In many cases, the exact cause of hydrocephalus cannot be identified.
Related serious diseases
Sometimes, Brain fog may be related to these serious diseases:
The liver removes toxins like ammonia from the blood. In liver failure, these toxins build up in the body and brain, causing confusion and abnormal behavior.
