encephalitis, inflammation, irritation, swelling, the brain, infections, meningitis encephalitis, often, a viral infection, many types of viruses, exposure to viruses, insect bites, food, drink contamination, inhalation of respiratory droplets, infected person, skin contact, in rural areas, arboviruses, carried by mosquitoes, ticks, accidentally ingested, the most common cause, in urban areas, enteroviruses, most common, coxsackievirus, poliovirus, echovirus, herpes simplex infection, varicella, chickenpox, shingles, measles, mumps, rubella, adenovirus, rabies, west nile virus, extremely rarely, vaccinations, once the virus has entered the bloodstream, localize, in the brain, causing inflammation of brain tissue, surrounding membranes, white blood cells invade the brain tissue, they try to fight off the infection, brain tissue swells, cerebral edema, destruction of nerve cells, bleeding, the brain, intracerebral hemorrhage, brain damage, encephalitis is uncommon, affects approximately 1,500 people per year, elderly, infants, more vulnerable, more severe course, fever, headache, vomiting, light-sensitivity, the eyes, stiff neck, confusion, disorientation, drowsiness, clumsiness, unsteady gait, irritability, poor temper control, emergency symptoms, loss of consciousness, poor responsiveness, stupor, coma, seizures, muscle weakness, paralysis, sudden onset of, memory loss, amnesia, impaired short-term memory, impaired long-term memory, "flat" mood, lack of discernible mood, mood inappropriate, the situation, diminished interest in daily activities, inflexibility, extreme self-centeredness, indecisiveness, withdrawal from social interaction, impaired judgment, various symptoms resembling meningitis present, an examination, signs of meningeal irritation, neck stiffness, increased intracranial pressure, neurologic symptoms muscle weakness, mental confusion, speech problems, abnormal reflexes, skin rash, mouth ulcers, signs of involvement of other organs the liver, lungs, a lumbar puncture test, cerebrospinal fluid, csf, examination, clear fluid, high pressure, high white blood cell count, protein levels, indications of inflammation, blood present, in the csf, the virus, detected in csf, blood, urine, a laboratory test, viral culture, test is cumbersome, rarely useful, viral pcr, polymerase chain reaction, a test able to detect very tiny amounts of viral dna, identify the virus, health care providers also rely on serology tests, serologies detect some proteins, antibodies, produced in response to an specific virus, evidence of viral infection, an eeg, a test, the electrical activity, the brain, provide indirect clues, the diagnosis of encephalitis, eeg wave patterns, suggest a seizure disorder, point to a specific virus, the infection, certain eeg wave patterns, suggest encephalitis, due to herpes, instance, a brain mri, provides high-quality pictures, the brain, a cat scan, the head used, internal bleeding, focal areas of brain inflammation, goals of treatment, supportive care, relieve symptoms, antiviral medications, herpes encephalitis, severe viral infections, the time, no specific antiviral drugs, combat the infection, antibiotics, the infection, organisms, certain bacteria, anti-seizure medications, such a phenytoin, suppress seizures, on rare occasions, potent anti-inflamatory drugs, steroids, dexamethasone, reduce brain swelling, sedatives needed to treat irritability, restlessness, medications, acetaminophen, fever, headache, supportive care, rest, nutrition, fluids, allows the body to fight the infection, reorientation, emotional support of confused, delirious persons helpful, brain function is severely affected, interventions, physical therapy, speech therapy necessary, acute illness, controlled, outcome, short, relatively benign followed by full recovery, severe, permanent impairment, death is possible, acute phase, lasts, 1 to 2 weeks, gradual, sudden resolution of fever, neurologic symptoms, neurologic symptoms, require many months, full recovery, permanent neurologic impairments to memory, speech, vision, hearing, muscle control, sensation, occur in people who survive severe cases of encephalitis, go, sudden fever, neurologic changes, symptoms suggestive of encephalitis occur, controlling mosquitoes, a mosquito bite, transmit some viruses, reduce the chance of some infections, lead to encephalitis, animal vaccination is important, prevent encephalitis, rabies virus, vaccination is available, prevent a form of viral encephalitis that often affects people living in dorms, military.
