1. What is a seizure?
A sudden, uncontrolled disturbance in the electrical activity in the brain is called a seizure. Seizures leads to changes in the level of consciousness, feelings, behaviour, and movements or feelings. The tendency of having recurrent or multiple seizures suggests a condition called epilepsy.
2. What are the various types of seizure?
Depending on the severity of seizures, they are classified into different types. Generalized seizures can be classified as:
-Tonic-clonic or convulsive seizures or grand mal (seizures with falling down and tongue biting)
-Absence seizures or petit mal (blank staring spells)
-Atonic seizures or drop attacks.
3. How do you diagnose a seizure?
Following steps will be carried out to diagnose seizure:
-Physical examination, medical history, and neurological examination (for testing of behaviour, mental or motor abilities)
-Blood tests (blood sugar, electrolyte imbalances)
-Lumabar puncture (infections)
-Imaging tests, EEG, CT scan, MRI, PET, and SPECT(brain activity, localise seizures, record blood flow in the brain)
4. What happens during an episode of seizure?
Symptoms of seizure include:
-The confusion which is temporary or loss of consciousness
-A staring spell
-Jerky movement including arms and legs, which are uncontrollable
5. Can a seizure be fatal?
Seizures can be fatal if they are recurrent, severe or multiple occurring as they kill neurons and lead to chronic epilepsy. Single and isolated seizures do not kill neurons.
