Study Notes
Convulsions
- Definition: Paroxysmal involuntary brain dysfunction that manifests as impaired consciousness, abnormal motor activity, behavioral abnormalities, sensory or autonomic dysfunction.
Causes of Acute Seizures in Infants and Children
- Fever
- Intracranial infections
- Encephalopathy (post-immunization)
- Metabolic and electrolyte disturbances
- Intoxications:
- Endogenous (uremia or hepatic encephalopathy)
- Exogenous (acute lead poisoning, drugs like theophylline, isoniazid)
- Head trauma (ICH, subdural Hge)
- Non-traumatic ICH (due to AV malformation and bleeding disorders)
- Hypertensive encephalopathy
- Cerebral ischemia:
- Arterial spasm, thrombosis, or embolism
- Venous thrombosis
- Circulatory collapse
- Brain anoxia
Diagnosis
- Arterial blood gases and electrolytes, LFT, KFT
- CSF examination
- Blood, urine, and CSF culture and sensitivity
- Tuberculin test
- Blood picture
- Coagulation profile
- Skull X-ray and CT scan (AVM, craniostenosis)
- Toxin screen in urine and serum
Febrile Convulsions
- Very common convulsive disorder during childhood with excellent prognosis
- Meticulous examination necessary to exclude serious underlying infectious disease
- Age range: 9 months to 5 years (peak: 14-18 months)
- Positive family history in 20%
- Convulsions start at the onset of rapid rise in body temperature
- Typical febrile convulsions are:
- Generalized tonic clonic
- Brief
