Naegleriasis, also known as primary amoebic meningoencephalitis (PAM), is an almost invariably fatal infection of the brain by the free-living unicellular eukaryote Naegleria fowleri. Symptoms are meningitis-like and include headache , fever , nausea , vomiting , a stiff neck , confusion , hallucinations and seizures . [ 6 ]
Some of the possible symptoms of chronic meningitis (due to any cause) include headache, nausea and vomiting, fever, and visual impairment. Nuchal rigidity (or neck stiffness with discomfort in trying to move the neck), a classic symptom in acute meningitis, was seen in only 45% of cases of chronic meningitis with the sign being even more rare in non-infectious causes.
It can be caused by a bacterial infection, such as bacterial meningitis, [17] or may be a complication of a current infectious disease such as syphilis (secondary encephalitis). [ 18 ] Other bacterial pathogens, like Mycoplasma and those causing rickettsial disease , cause inflammation of the meninges and consequently encephalitis.
Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency. [2] [8] A lumbar puncture, in which a needle is inserted into the spinal canal to collect a sample of cerebrospinal fluid (CSF), can diagnose or exclude meningitis. [1] [8]
That can lead to the brain infection and abscesses that Bragg described. These complications are more likely to develop in kids and teens because of the way the sinuses develop as children get older.
Rarely, treated individuals can have relapse of infection weeks to months later. There is evidence that aberrant inflammation triggered by herpes simplex can result in granulomatous inflammation in the brain, which responds to steroids. [16] While the herpes virus can be spread, encephalitis itself is not infectious.
Doing so can provide at least temporary relief, but doctors now believe that a Seattle woman's fatal brain condition may have been linked to her use of the product.
