The meninges are the layers of thin tissue that cover your brain. If these tissues become infected, it’s called meningitis. When your brain becomes inflamed or infected, the problem is called encephalitis. If both the meninges and the brain are infected, the condition is called meningoencephalitis. Encephalitis involving herpes is a medical emergency. He had a general seizure at admission. This disease is often fatal when it is not treated.
All, however, had CSF findings that distinguished them from herpes cases. Encephalitis is caused by the herpes simplex virus. Most are caused by herpes simplex virus type 1 (HSV1), the virus that also causes cold sores. The disease may also be caused by herpes virus type 2 (HSV2). This virus can be spread by sexual contact or from an infected mother to her baby during childbirth. HSV1 infection can also be sexually transmitted to the genital area. These viruses remain in the body throughout a person’s life, even when they’re not causing signs of infection.
If you have viral meningitis, symptoms may include fever, light sensitivity, headache, and a stiff neck. If you have other symptoms, such as confusion, seizures, sleepiness, or a focal neurologic deficit—a nerve function problem that affects a specific area — these may suggest that your brain is also affected, and your healthcare provider may diagnose it as meningoencephalitis. Neurological exam. Your provider will do a neurological exam to look for changes in motor and sensory function, vision, coordination and balance, mental status, and in mood or behavior. Lumbar puncture. In this procedure, your provider will take a sample of spinal fluid. Cells and other substances in this fluid may give your provider important clues.
Imaging. Hemorrhagic complication occurred during acyclovir treatment (5-15 days) in six patients, suggesting that initiation of treatment may not affect this complication. EEG. An EEG measures brain waves by placing electrodes onto your scalp. Blood tests. Testing the blood helps identify infection. If your healthcare providers think that a newborn has herpes encephalitis resulting from infection with HSV2 while passing through the birth canal, they may check samples of the baby’s blood and spinal fluid.
Treating the cause of your infection is the primary treatment. Since most cases of meningoencephalitis are caused by the herpes virus, the antiviral acyclovir is used to treat it. You may need to take this medicine through an intravenous (IV) line for 10 to 14 days. Your healthcare provider may also give you medicine to reduce swelling in the brain and to treat or prevent seizures. With treatment, most people with this disease start to improve within a day or two and tend to recover fully within about a month. But without treatment, very serious complications can set in, including death. Even with treatment, some people with severe cases may have long-term brain damage.
They may have trouble thinking, controlling their body, and hearing, seeing, or speaking. They may need to take medicines for a long time, and they may require long-term care. Abstain from sex or have only one sex partner who has been tested for the virus and isn’t infected. Use a latex condom, which can reduce — but not entirely prevent — the risk of infection. Avoid kissing people with cold sore blisters. It’s important to keep in mind that most people have already been infected with HSV1 virus by the time they’re 20 years old. If you’ve already been infected, the virus goes dormant inside your body except during outbreaks.
Treating herpes meningoencephalitis as soon as possible is essential. If you’re feeling neck stiffness, having any neurological problems (including seizures, changes in consciousness, or feeling sleepy), are sensitive to light, or are running a fever along with a bad headache, call your healthcare provider and have the problem treated promptly. If you have already been diagnosed with herpes meningoencephalitis and are being treated, it’s very important to let your healthcare providers know if any of your symptoms get worse or if you develop any new symptoms, as these could be signs that the infection is getting worse despite treatment. Know the reason for your visit and what you want to happen. It is a medical emergency that requires treatment right away. Symptoms can include headache, fever, changes in consciousness, confusion, neck stiffness, sensitivity to light, seizures, and changes in mood, personality, or behavior. Treatment is with antiviral medicine, sometimes along with other medicines such as steroids and drugs to prevent seizures.
Know the reason for your visit and what you want to happen. Before your visit, write down questions you want answered. Bring someone with you to help you ask questions and remember what your provider tells you. At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you. Know why a new medicine or treatment is prescribed, and how it will help you. Also know what the side effects are.
Ask if your condition can be treated in other ways. Know why a test or procedure is recommended and what the results could mean. Know what to expect if you do not take the medicine or have the test or procedure. If you have a follow-up appointment, write down the date, time, and purpose for that visit. Know how you can contact your provider if you have questions. © 2000-2016 The StayWell Company, LLC. 780 Township Line Road, Yardley, PA 19067.
