Amoebic meningoencephalitis
Overview
Amoebic meningoencephalitis is a rare but serious infection caused by amoebas that can enter the body through the nose and travel to the brain. These amoebas are usually found in bodies of fresh water, such as lakes and rivers. Once inside the brain, they cause inflammation and destruction of the brain tissue, leading to symptoms such as severe headaches, fever, nausea, and confusion. Unfortunately, the infection is often fatal, with a high mortality rate even with treatment.
Diagnosing amoebic meningoencephalitis can be challenging as the symptoms are similar to other more common infections. It usually requires a sample of cerebrospinal fluid obtained through a lumbar puncture to confirm the presence of the amoebas. Treatment typically involves aggressive use of antiparasitic medications, but even with treatment, the prognosis is often poor due to the rapid progression of the disease. Prevention is key in avoiding this deadly infection, which includes avoiding swimming or diving in warm freshwater bodies, especially in areas where the amoebas are known to be present.

Types of Amoebic meningoencephalitis
There are two types of amoebic meningoencephalitis: primary amoebic meningoencephalitis (PAM) and granulomatous amoebic meningoencephalitis (GAM).
Primary amoebic meningoencephalitis (PAM) is a rare but serious brain infection caused by the amoeba Naegleria fowleri. This amoeba is commonly found in warm freshwater environments and enters the body through the nose. Once inside, it travels to the brain and causes inflammation and destruction of brain tissue, leading to symptoms such as severe headache, fever, nausea, and confusion. PAM progresses rapidly and is usually fatal within a few days.
Granulomatous amoebic meningoencephalitis (GAM) is caused by other species of amoeba, such as Acanthamoeba and Balamuthia mandrillaris. These amoebae are found in soil and water and can enter the body through open wounds or through the respiratory system. GAM is less common than PAM but usually affects individuals with weakened immune systems. The infection progresses more slowly than PAM, with symptoms including headache, fever, stiff neck, and neurological deficits. GAM is difficult to diagnose and treat, and the prognosis is often poor.
Diagnostic of Amoebic meningoencephalitis
Amoebic meningoencephalitis is diagnosed by doctors using a variety of methods. One common way is through a spinal tap, where a small amount of cerebrospinal fluid is taken from the spine and tested for the presence of amoebas. Imaging tests such as CT scans or MRIs may also be used to look for signs of infection or inflammation in the brain.
Additionally, doctors may conduct blood tests to check for antibodies that the body produces in response to the amoebas.
