There are seizures may be described as either partial (focal) or generalised. Partial seizures only involve a localised part of the brain, whereas generalised seizures involve the entire cortex. The term “secondary generalization” may be used to describe a partial seizure that later spreads to the whole of the cortex and becomes generalised. I have the “secondary generalization” seizures because the operation.

Absence seizures (sometimes referred to as petit mal seizures) involve an interruption to consciousness where the person experiencing the seizure seems to become vacant and unresponsive for a short period of time (usually up to 30 seconds). Slight muscle twitching may occur.

Tonic-clonic seizures (sometimes referred to as grand mal seizures), involve an initial contraction of the muscles (tonic phase) which may involve tongue biting, and the absence of breathing. This is followed by rhythmic muscle contractions (clonic phase). This type of seizure is usually what is referred to when the term 'epileptic fit' is used colloquially. These tend to be accompanied by intense visions or hallucinations.

If I have a grand mal, the first thing I must do is calm down, stop panicking (an understandable reaction, though), and help with someone that might be with me. If I have to deal with by myself, that is okay and I must lie down on my side. They need to ensure that my airway is clear and open to maintain breathing. Potentially sharp or dangerous objects should also be moved, so that I do not hurt myself.
