Amoebic Meningitis: Symptoms and Risks
Amoebic meningitis is a rare but serious infection that affects the brain and spinal cord. It is caused by a microscopic amoeba entering the body through contaminated water sources. This infection can have a severe impact on health as it can lead to inflammation of the protective membranes covering the brain and spinal cord. The consequences of amoebic meningitis can be life-threatening and require prompt medical attention.
What are the Symptoms of Amoebic Meningitis?
Amoebic Meningitis typically presents with a range of symptoms affecting the central nervous system.
- Severe headache
- Fever
- Stiff neck
- Nausea and vomiting
- Sensitivity to light
- Confusion
- Seizures
- Hallucinations
- Loss of appetite

Get Second OpinionCauses of Amoebic Meningitis
Amoebic meningitis is primarily caused by the Naegleria fowleri amoeba entering the body through the nose and migrating to the brain.
- Naegleria fowleri amoeba entering the body through the nose
- Contaminated water sources
- Lack of proper water treatment
- Warm freshwater environments
Types of Amoebic Meningitis
Amoebic meningitis can present in various forms, each with its own set of symptoms and treatment options.
- Primary Amoebic Meningoencephalitis (PAM): A rare but often fatal infection caused by the Naegleria fowleri amoeba found in warm freshwater bodies.
- Granulomatous Amoebic Encephalitis (GAE): A serious infection primarily caused by Acanthamoeba and occasionally by Balamuthia mandrillaris, leading to brain inflammation and tissue damage.
- Disseminated Amoebic Infection: Occurs when amoebas spread beyond the central nervous system to other organs, causing systemic illness and potential complications.
- Chronic Amoebic Meningitis: A long term infection usually caused by free living amoebas like Acanthamoeba, leading to ongoing inflammation of the meninges.
- Meningoencephalitis due to Parasitic Amoebae: Rare infections caused by various amoebae species, leading to inflammation of the brain and its surrounding membranes.
Risk Factors
Amoebic meningitis risk factors include activities involving warm freshwater, particularly in certain regions, and individuals with weakened immune systems.
- Swimming in warm freshwater bodies
- Using untreated water for nasal irrigation
- Having a weakened immune system

Diagnosis of Amoebic Meningitis
Amoebic meningitis is typically diagnosed through a combination of clinical symptoms, medical history, and specialized tests.
- Lumbar Puncture
- Brain Imaging (CT scan or MRI)
- Blood Tests
- PCR Testing
Treatment for Amoebic Meningitis
Amoebic meningitis is typically treated with medications to target the parasite causing the infection.
Antimicrobial Medications:
- Antibiotics are commonly prescribed to treat amoebic meningitis by targeting the amoebas causing the infection.
Antifungal Drugs:
- In some cases, antifungal medications may be used alongside antimicrobial drugs to effectively combat the infection.
Corticosteroids:
- Corticosteroids are often given to reduce inflammation in the brain caused by the infection and alleviate symptoms.
Intravenous Fluids:
- Maintaining hydration through intravenous fluids is crucial in supporting the body's recovery and preventing complications.
Supportive Care:
- Patients with amoebic meningitis may require supportive care, including rest, pain management, and close monitoring of their condition.
