Overview
History and Symptoms
In the study by Durand et.al., only 2/3 of patients had the classic triad of fever, nuchal rigidity and change in mental status.
- All patients, however, had at least one of these findings.
- 95% had fever >100 degrees Fahrenheit, with a mean duration of 4 days.
- Neck stiffness was present in 88%, and contrary to other reports, was not significantly lower amongst the elderly.
- 11% of patients had a rash, and of these cases 73% of them were due to Neisseria meningitidis (most commonly petechiae and purpura)
- 78% of patients had an abnormal mental status, primarily lethargy and confusion and 23% of the patients had focal seizures.
In general
- Headache is the most common symptom of meningitis (87%)
- Nuchal rigidity ("neck stiffness", 83%).
- Fever
- Altered mental status.
All three features are present in only 44% of all cases of infectious meningitis.[1]
Other symptoms commonly associated with meningitis are
- Photophobia (inability to tolerate bright light)
- Phonophobia (inability to tolerate loud noises)
- Irritability
- Delirium (in small children)
- Seizures (in 20-40% of cases)
- Swelling of the fontanelle (soft spot) may be present in infants (0-6 months).
- Vomiting may be present.
