Study Notes
Nervous System Infections
- The nervous system consists of the brain, spinal cord, and nerves.
- Meningitis is an inflammation of the membranes surrounding the brain and spinal cord.
- Meningitis is typically caused by an infection.
- An MRI (magnetic resonance imaging) uses radio waves and a magnet to create detailed images of the body's interior.
- Meningitis occurs when microbes enter the normally sterile meninges, causing infection.
Meningitis
- Meningitis is an inflammation of the meninges, which are the protective coverings of the brain and spinal cord.
- It is a global disease, with varying prevalence rates.
- Bacterial, viral, and fungal infections are common causes.
- Children are at higher risk for meningitis.
- Meningitis can be a complication of other illnesses, such as measles, mumps, malaria, and ear infections.
Recognizing Meningitis
- Symptoms include high fever, vomiting, severe headache, and stiff neck.
- Infants may exhibit a bulging fontanel (soft spot).
- Late-stage symptoms include seizures, convulsions, and a rash that does not fade with pressure.
- Other symptoms include restlessness, unusual crying, excessive sleepiness, and sensitivity to light.
Importance of Early Diagnosis
- Prompt medical attention is vital, as meningitis can be fatal.
- Seek immediate medical help if you notice any symptoms, especially in infants and children.
- Early diagnosis and treatment significantly improve survival chances.
