- A bulging soft spot on the head. This may also be followed with separated sutures, typically found in babies.
- Fatigue (lethargy). Sometimes it may occur with vomiting.
- Increased size of head circumference.
- Weakness /paralysis on both sides of the body.
- The problem may also cause seizures.
Subdural infection is one of rare complications of meningitis. Although it is more common in infants, but this doesn’t mean it cannot affect adults (especially for those who have H. influenzae meningitis, an infection caused by ‘Haemophilus influenzae’ bacteria).
It is typically characterized by a pulsing sensation /throbbing pain on one side of the head. It may also come with other discomfort symptoms such as more sensitive to light, extreme sensitivity to sound, nausea, and vomiting.
The link between migraine headache and bacterial meningitis may be still debatable. For example, while some studies suggest that meningococcal meningitis has nothing to do with the long-term risk of migraine, others show that some patients who have had meningococcal meningitis might have increased risk of migraine.
Meningococcal meningitis may cause blood poisoning (septicemia). The infection can enter the bloodstream and release harmful toxins. This may also affect your kidneys, leading to kidney problems.
Septicemia is a serious, life-threatening condition. It must be treated immediately! It can occur with or without bacterial meningitis.
How about hydrocephalus?
Hydrocephalus is a condition in which there is a collection of fluid inside the skull. Fluid surrounding the brain is essential to help cushion the brain – this fluid is called CSF (cerebrospinal fluid).
But if there is too much CSF, this can be counterproductive and put extra pressure on the brain. It can cause brain swelling especially in babies. Other symptoms may include vomiting, drowsiness, forgetfulness, irritability, or urinary incontinences in adults.
Hydrocephalus is more common in babies and children. Another type of the disease called NPH (normal pressure hydrocephalus) may also affect adults.
Hydrocephalus in babies and children could be a consequence of bacterial meningitis. But it seems that NPH has nothing to do with meningitis!
Meningitis can cause serious complications or even life-threatening if not treated immediately. Again, see a doctor promptly if you have any symptom of the disease!
