Yes, the flu can cause confusion.
Understanding Flu-Related Confusion
Confusion is a serious symptom that can sometimes occur with influenza (flu). It's not just a typical feeling of being unwell; it indicates a more significant impact of the virus on the brain. It's important to understand when confusion linked to the flu might warrant further medical attention.
How Does the Flu Cause Confusion?
When the influenza virus infects the body, it can sometimes lead to inflammation that affects the brain. This can manifest as confusion, which is a type of altered mental status.
- Influenza Encephalopathy: In severe cases, the flu can cause inflammation of the brain, known as influenza encephalopathy. This condition is directly linked to altered mental states, including confusion, even in the absence of fever.
- Focal Neurological Symptoms: Besides confusion, the flu can also cause focal neurological symptoms like aphasia (difficulty speaking).
When to Seek Medical Attention
It is crucial to seek medical attention if you or someone you know experiences confusion along with flu-like symptoms.
| Symptom | Significance |
|---|---|
| Confusion | A clear sign of more severe influenza affecting the brain. |
| Focal neurological symptoms | Such as aphasia; indicates need for immediate evaluation. |
| Altered mental status | Can occur with or without fever and requires evaluation during flu season. |
Reference: Learning points. Confusion and focal neurological symptoms including aphasia should prompt influenza testing in influenza season. Influenza encephalopathy can present as afebrile altered mental status.10-Oct-2020
