Can a flu virus affect the nervous system?
Influenza virus infections are predominantly restricted to the respiratory tract, with central nervous system (CNS) disease the most common extrarespiratory complication [1]. Neurological symptoms include febrile seizures, acute brain dysfunction, Reye syndrome, (meningo)encephalitis, and encephalopathy.
What virus attacks the nervous system?
Herpes simplex virus type 1 (HSV-1) is highly prevalent in humans and can reach the brain without evident clinical symptoms.
Can a virus attack your central nervous system?
Viruses affect the central nervous system in two ways: They can directly infect and destroy cells in the central nervous system and cause local swelling during the acute illness. Certain viral infections elsewhere in the body can cause the immune system to attack and damage cells around the nerves.
Which virus causes flu like symptoms and can attack the nervous system?
Encephalitis often causes only mild flu-like signs and symptoms — such as a fever or headache — or no symptoms at all. Sometimes the flu-like symptoms are more severe. Encephalitis can also cause confused thinking, seizures, or problems with movement or with senses such as sight or hearing.
Can the flu infect your brain?
Brain flu is a very rare neurological complication of the influenza virus. It can lead to an altered mental status and other neurological symptoms.
Can the common flu cause brain damage?
Encephalitis. Encephalitis is a rare condition occurs when a flu virus enters the brain tissue and causes inflammation of the brain. This can lead to destroyed nerve cells, bleeding in the brain, and brain damage.
Can you repair your central nervous system?
There is no such repair process in the central nervous system, thus injuries often lead to permanent damage such as paraplegia,” explains Claire Jacob, Head of Cellular Neurobiology at JGU. Strategies to improve axon regeneration in the central nervous system must therefore be developed to enable healing.
How do you confirm GBS?
The clinical diagnosis of GBS needs to be confirmed by cerebrospinal fluid analysis and nerve conduction studies. Lumbar puncture is indicated in every case of suspected GBS.
Can you have a virus in your brain?
Primary encephalitis occurs when a virus directly infects the brain and spinal cord. Secondary encephalitis occurs when an infection starts elsewhere in the body and then travels to your brain. Encephalitis is a rare yet serious disease that can be life-threatening.
Can your brain swell from the flu?
Once inside the blood, the viruses migrate to the brain where they start to multiply. The body notices the invasion and mounts an immune system response. This causes the brain to swell. The combination of infection and immune response creates the typical symptoms of viral encephalitis.
Can the flu cause long term complications?
They include viral or bacterial pneumonia, dehydration, and ear infections and sinus infections, especially in children. The flu can worsen long-term medical conditions, like congestive heart failure, asthma, or diabetes.
What happens to your brain when you have the flu?
The infections also activated the brain’s immune cells in this region for an extended period and altered the expression of genes implicated in disorders including depression, autism and schizophrenia. These findings suggest that some strains of the flu may pose a threat to healthy brain function.
