Tuberculous meningitis

Tuberculous Meningitis

1. Definition Tuberculous meningitis is an infection of the protective membranes covering the brain and spinal cord, known as the meninges, caused by the bacterium Mycobacterium tuberculosis.

2. Causes / Etiology Mycobacterium tuberculosis, the causative organism of tuberculosis, is the primary cause of tuberculous meningitis. This bacterium is usually spread through the air when an infected person coughs, sneezes, or talks.

3. Types or Classification

• Acute Tuberculous Meningitis: This is the most common form of the disease, characterized by a sudden onset of symptoms.
• Subacute Tuberculous Meningitis: This form of the disease progresses slowly over several weeks.
• Chronic Tuberculous Meningitis: This is a rare form of the disease that develops slowly over several months.

4. Pathology Step 1 → The bacteria, Mycobacterium tuberculosis, enter the body through the lungs. Step 2 → The bacteria then spread to the bloodstream and are carried to the brain and spinal cord. Step 3 → Once in the brain and spinal cord, the bacteria infect the meninges, causing inflammation and damage to the protective membranes. Step 4 → As the infection progresses, the meninges thicken and become fibrotic, leading to increased intracranial pressure. Step 5 → The infection can also cause damage to the brain and spinal cord tissue, leading to a range of neurological symptoms.

5. Clinical Features

• General Features: Fever, headache, stiff neck, and confusion are common symptoms of tuberculous meningitis.
• Specific Features: Seizures, decreased level of consciousness, and cranial nerve palsies are also common.

6. Complications

• Acute Complications: Increased intracranial pressure, seizures, and respiratory failure are common acute complications.
• Chronic Complications: Hydrocephalus, cerebral atrophy, and neurological deficits are common chronic complications.

7. Diagnosis / Investigations

• Routine Tests: Complete blood count, erythrocyte sedimentation rate, and cerebrospinal fluid examination are used to diagnose tuberculous meningitis.
• Special Tests: Tuberculin skin test, interferon-gamma release assay, and PCR are used to confirm the diagnosis.

8. Management

• General Management: Rest, hydration, and pain management are essential in the management of tuberculous meningitis.
• Modern Treatment: Antitubercular therapy, which includes a combination of antibiotics, is the mainstay of treatment.
• Dietary Advice: A balanced diet rich in vitamins and minerals is essential to support recovery.
