Pediatric CNS infections
1. Overview
Pediatric CNS infections (Central Nervous System infections) are serious conditions that affect the brain and spinal cord in children. These infections can involve the meninges (meningitis), brain tissue (encephalitis), or spinal cord, and may lead to severe neurological complications if not treated promptly.
Early diagnosis and urgent medical care are essential to protect the child’s brain function and overall development.
2. Types
We diagnose and treat a wide range of central nervous system infections in children, including:
- Meningitis (Bacterial & Viral)
- Encephalitis
- Brain Abscess
- Tubercular Meningitis
- Spinal Infections
- Neurocysticercosis
Each condition requires timely and specialized pediatric neurological care.
3. Causes & Risk Factors
CNS infections in children are caused by various microorganisms, such as:
- Bacteria (e.g., meningococcal, pneumococcal infections)
- Viruses (e.g., viral encephalitis)
- Fungi (in rare cases)
- Parasites (e.g., neurocysticercosis)
These infections can spread through the bloodstream or directly affect the brain and spinal cord tissues.
4. Signs & Symptoms
Symptoms of CNS infections in children may appear suddenly and worsen quickly.
Common Symptoms Include:
- High fever
- Severe headache
- Neck stiffness
- Vomiting
- Seizures
- Sensitivity to light (photophobia)
- Altered consciousness or confusion
In Infants:
- Bulging soft spot (fontanelle)
- Poor feeding
- Excessive crying or irritability
- Lethargy
⚠️ These symptoms require immediate medical attention
5. Diagnosis
Early and accurate diagnosis is critical for managing brain infections in children.
Diagnostic Methods Include:
- Blood tests
- Lumbar puncture (CSF analysis)
- MRI Brain / CT Scan
- EEG (if seizures are present)
- Microbiological testing
These tests help identify the cause and severity of infection.
