1. What is a seizure?
It is the changes in the consciousness, behaviour, feeling and movements of the person due to abnormal electrical activity in the brain. Recurrent episodes of seizures are called epilepsy.
2. What are the various types of seizure?
Seizures are classified based on the symptoms and the two major categories include: generalised seizures affects both sides of the brain and includes absence seizures and tonic-clonic seizures, and focal seizures affects only one side of the brain and includes simple focal seizures, complex focal seizures and secondary generalised seizures.
3. How do you diagnose a seizure?
Seizures can be diagnosed in the following manner: medical history, neurological and physical examination, blood tests like blood sugar and electrolyte test, lumbar puncture and imaging tests like CT scan, MRI and electroencephalography.
4. What happens during an episode of seizure?
The following are the common symptoms of seizures: temporary confusion and loss of consciousness, fear and anxiety, and jerky and uncontrolled movements of arms and legs.
5. Can a seizure be fatal?
Yes, a seizure can be life-threatening if it is recurring and occurs several times. This is because it kills neurons and may also lead to chronic epilepsy. A single episode of seizure does not kill neurons.
