Factors or behaviors that increase the likelihood of developing the condition.
Severe stress, trauma, personality disorders, or legal pressure.
Prognosis:
The expected outcome or course of the condition over time.
Symptoms often resolve with appropriate psychological support and stress relief.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Misdiagnosis, prolonged distress, or functional impairment.
Naegleria Infection and Primary Amebic Meningoencephalitis (PAM)
Specialty: Infectious Diseases
Category: CNS Infections
Symptoms:
severe headache; fever; nausea; vomiting; stiff neck; seizures; altered mental status; hallucinations; coma
Root Cause:
Infection caused by the amoeba Naegleria fowleri, which invades the brain through the nasal passages, often following freshwater exposure.
How it's Diagnosed: videos
Analysis of cerebrospinal fluid (CSF) through lumbar puncture, identification of Naegleria in CSF via microscopy, polymerase chain reaction (PCR), or antigen testing; brain imaging (MRI or CT) for inflammation.
Treatment:
Aggressive antimicrobial therapy including amphotericin B (intravenous and intrathecal), supportive care for cerebral edema, and experimental medications like miltefosine.
Medications:
Amphotericin B (antifungal), miltefosine (antiparasitic), rifampin (antibiotic), fluconazole (antifungal), and azithromycin (antibiotic). These medications aim to target the amoeba directly and reduce associated inflammation.
Prevalence:
How common the health condition is within a specific population.
Rare; fewer than 150 cases reported in the United States over several decades. Occurs more frequently in warm climates with freshwater exposure.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Freshwater swimming or diving, particularly in warm lakes or hot springs; use of untreated water for nasal irrigation.
Prognosis:
The expected outcome or course of the condition over time.
Poor, with a mortality rate exceeding 97%; early diagnosis and treatment are critical for the few known survivors.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Rapidly progressing brain inflammation, brain herniation, coma, and death.
