A Convulsion is an episode of neurologic dysfunction caused by abnormal neuronal activity that results in sudden change in behavior, sensory perception, or motor activity. For a patient with new onset convulsion the list of possible causes is longer and consists of the following:
- CNS pathologies (stroke,neoplasm,trauma,hypoxia,vascular abnormality)
- Metabolic abnormalities (hypoglycemia/hyperglycemia,hyponatremia/hypernatremia, hyercalcemia, hepatic encephalopathy
- Toxicological etiologies (alcohol withdrawal, cocaine, isoniazid, theophylline)
- Infectious etiologies(meningitis,encephalitis,brain abscess,neurocycticercosis and malaria)
