The inflammation of the meninges is caused by a type of bacteria called Mycobacterium tuberculosis, which infects the membranes and develops the infection over time. It may take days or even years for the first signs of TB meningitis to be noticed, making it difficult to be diagnosed.
It is possible for anyone to develop TB meningitis but it is more likely to occur in developing countries with poor living conditions. Those at risk are people with weak immunity and young children.
TB meningitis causes
TB meningitis may result from a person inhaling the bacteria from a person infected with tuberculosis. It may also affect a person who is already infected with tuberculosis.
The bacteria travels into the membranes that surround the brain and spinal cord, which will begin to develop small abscesses. These abscesses may burst, causing TB meningitis. These swollen bumps may pop right away or months after the infection. It may even take years for them to burst, causing buildup of pressure in the skull.
Symptoms of TB meningitis
The symptoms of TB meningitis usually develop slowly but become much more severe as time passes. TB meningitis causes the following:
- Chronic or continuous headaches
- Aches and pains
- Appetite loss
- Fatigue and tiredness
- Stiff neck
Once the infection becomes more severe, the following symptoms may be noticed:
Because of the slow, gradual nature of the disease, TB meningitis may become difficult to diagnose and requires treatment as soon as the possible symptoms are observed.
