Unlikely: Brain infections are very rare but can be caused by viruses, bacteria or parasites. With normal ct and MRI it is quite unlikely you have a "brain infection" causing chronic headaches. I recommend you see a neurologist for a complete evaluation. You will have peace of mind when you have a clear diagnosis. ...Read more

Does encephalitis just happen at any time? The virus you had in the past is dormant in your system then transfers and infects the brain of some people? Or does it more commonly happen in the new infections of the virus' ?

Does encephalitis just happen at any time? The virus you had in the past is dormant in your system then transfers and infects the brain of some people? Or does it more commonly happen in the new infections of the virus' ?

Confusing question: The wording of your question is hard to follow. That said, there are some basics I can state. Most encephalitis viruses burn out and are essentially eliminated by the immune system.There transfer process is type specific, some in saliva during the illness, some by mosquitoes, once healed, you do not pass the virus to others. ...Read more

I was first diagnosed with tick borne encephalitis in 2009. Still get sick all the time. Now have brain damage as a result of the infection.?

Sorry to hear that: Unfortunately, encephalitis contracted from any source (ticks, mosquitos, etc.) can result in neurological dysfunction. If you were treated for the appropriate tick illness, there should not be any remaining infective agent, but it is possible that your immune system may be slightly disrupted. See you doctor for a reevaluation. ...Read more

How do you diagnose a brain infection?

How do you diagnose a brain infection?

CSF tests, imaging: While there are certain blood test results or MRI findings that raise the suspicion for infection, a definitive diagnosis often requires a lumbar puncture for analysis of cerebrospinal fluid. That being said, in many cases we will treat infections empirically just based on clinical suspicion, especially if the patient is presenting with seizures or other worrisome signs. ...Read more

Viral (herpes, hiv) or fungal brain infections are special situations - ask your doctor. ...Read more

Isit possible to get a brain infection if someone shuts a dirty, dust door a few inches from your face?

Isit possible to get a brain infection if someone shuts a dirty, dust door a few inches from your face?

Virtually never: The brain is protected from infection by many barriers: the skin of the head, the skull, nasal passages have mucus, the nasal mucosa has immune system cells, and inside the head there are protective membranes. It is almost impossible to inhale something as you describe and have it get through these barriers to cause an infection in the brain. ...Read more
