Meningitis occurs when a viral or bacterial infection spreads to or starts in the coverings around the brain or the spinal cord, resulting in severe inflammation. In most cases, young children and young adults are the most at risk; however, anyone with a compromised immune system can develop meningitis.Viral meningitis is the most common form of this illness, and it is generally not life threatening unless complications develop. Bacterial meningitis, however, is incredibly serious and can lead to brain damage or death if not treated immediately. The symptoms for both types of meningitis are the same, although viral meningitis may come on more slowly than bacterial.Common Symptoms of MeningitisIn many cases, the symptoms of meningitis mimic those of a severe flu. Muscle aches, weakness and tingling throughout the body are exceedingly common, and oftentimes the symptoms of meningitis are mistaken for the flu at first. In addition to this, patients almost always have a fever, and may experience prolonged and debilitating headaches. The combination of headaches and a fever can lead to vomiting.A person may become confused and have difficulty staying awake, and in severe cases, seizures may occur. Perhaps the most notable sign of meningitis, however, is the inability to move the neck downwards due to pain and stiffness in the neck: this is caused by inflammation in the brain and spinal cord. Some patients may also develop a rash on the skin, or experience sensitivity to light. Dizzy spells occurring when a person moves from a sitting to standing position may also occur.Symptoms of Meningitis in BabiesMeningitis can be slightly difficult to note in babies, as they cannot convey how they are feeling. However, the most common signs to watch for in young children are unusual irritability, especially when being held, and a decrease in appetite and vomiting. A baby with meningitis will often emit a high-pitched cry, and will likely develop a rash somewhere on his or her body. When a child is young enough to have an open "soft spot" on his or her head, this area may bulge out, and the baby's entire body may become stiff.
