The following symptoms and complaints may indicate bacterial meningitis (bacterial meningitis):
Leading symptoms
- Severe headache (> 5 on the visual analog scale (VAS); approximately 90% of cases).
- Septic fever (> 38.5 °C; 50-90% of cases)
- Meningismus (painful neck stiffness) (about 80% of cases; need not occur in children, unlike adults) [late symptom].
- Impaired consciousness ranging from lethargy (lack of drive), somnolence (drowsiness with abnormal sleepiness while maintaining responsiveness and arousability) to coma (about 75% of cases) [late symptom]
Notice:
- Triad of fever, meningismus and impaired consciousness occurs in less than half of all patients with bacterial meningitis!
- In immunosuppressed patients, fever and/or headache may be absent – often acute disturbance of consciousness is the only leading symptom.
Associated symptoms
- General feeling of illness
- Vertigo (dizziness)
- Irritability
- Confusion
- Nausea/vomiting (as a sign of increased intracranial pressure/brain pressure).
- Photophobia (photophobia)
- Skin lesions
- Diffuse erythematous maculopapular exanthema – rash with small papules.
- Petechiae (flea-like bleeding; due to disseminated intravascular coagulopathy/blood clotting disorder (DIC)) (about 25% of cases)
-
Focal neurological symptoms, such as.
- Cranial nerve and limb paresis (paralysis) or
- Aphasia (Greek ἀφασία aphasía “speechlessness”).
- Epileptic seizures
Other indications
- Boys are more likely to complain of headaches, girls are more likely to have seizures
- Older children were more likely to be sensitive to light and pain
- Tuberculous meningitis: early stage of the disease rather nonspecific; very slow progression with subacute disease course:
-
- Fever, loss of appetite, headache, vomiting, photophobia (photophobia; sensitivity to light).
- Clinical signs: Meningismus (painful neck stiffness), coma, cranial nerve palsy, confusion, hemiparesis (hemiplegia/paraparesis (incomplete paralysis of both legs), epileptic seizures/convulsions (50% in children; 5% in adults).
