Introduction:

Mollaret meningitis, also known as recurrent aseptic (non-bacterial) meningitis, is a rare and recurrent form of meningitis characterized by recurrent episodes of inflammation of the membranes surrounding the brain and spinal cord. Unlike bacterial meningitis, Mollaret meningitis is typically caused by viral infections and is characterized by its recurrent nature. This article provides a comprehensive overview of Mollaret meningitis, including its causes, symptoms, diagnosis, and treatment.

Causes of Mollaret Meningitis:

• Herpes Simplex Virus (HSV): The most common cause of Mollaret meningitis is HSV, specifically HSV-2, which is typically associated with genital herpes.
• Other Viral Infections: In some cases, other viral infections, such as Epstein-Barr virus (EBV) or enteroviruses, may trigger Mollaret meningitis.

Symptoms of Mollaret Meningitis:

• Recurrent Meningitis Episodes: The hallmark of Mollaret meningitis is recurrent episodes of meningitis, each lasting for a few days to a week.
• Headache: Severe headaches are a common symptom during meningitis episodes.
• Fever: Elevated body temperature is often present during episodes.
• Neck Stiffness: Stiffness of the neck and pain when bending it forward (neck stiffness) is a classic symptom of meningitis.
• Photophobia and Phonophobia: Sensitivity to light (photophobia) and sound (phonophobia) may occur.

Diagnosis of Mollaret Meningitis:

• Cerebrospinal Fluid (CSF) Analysis: Analysis of the CSF through a lumbar puncture (spinal tap) is necessary for diagnosis. The CSF typically shows an elevated white blood cell count and increased protein levels.
• Viral PCR: Polymerase chain reaction (PCR) tests can identify the presence of viral DNA, such as HSV DNA, in the CSF.
• Blood Tests: Blood tests may be conducted to check for viral antibodies.

Treatment of Mollaret Meningitis:

• Antiviral Medications: Antiviral drugs, such as acyclovir, may be prescribed to manage and suppress viral replication during active episodes.
• Pain Relief: Pain relievers and anti-inflammatory medications can help alleviate symptoms such as headaches and fever.
• Preventive Measures: For individuals with recurrent Mollaret meningitis, long-term antiviral therapy may be considered to prevent future episodes.

Prevention:

• Safe Sexual Practices: Since HSV-2 is a common cause of Mollaret meningitis, practicing safe sex and using barrier methods like condoms can reduce the risk of HSV transmission.
• Avoiding Triggers: Identifying and avoiding triggers, such as stress or illness, that may lead to recurrent episodes can be helpful.

Conclusion:

Mollaret meningitis is a rare and recurrent form of viral meningitis, often triggered by HSV-2 or other viral infections. While it can be challenging to manage due to its recurrent nature, antiviral medications and preventive measures can help individuals with Mollaret meningitis lead a more comfortable life with fewer meningitis episodes.
