Tonic clonic seizures, previously known as grand mal seizures, are a form of epilepsy. These seizures occur in both adults and children.
 
 Normally, these seizures occur in one part of the brain. However, they may spread to both sides of the brain. Generally, they last for less than a minute, but they can last up to three minutes. The person experiencing the seizure may begin to feel drowsy, confused, or tired. They may also fall or become unconscious.
 
 In a tonic clonic seizure, the person loses consciousness and stiffens the muscles on one or both sides of the body. This can be frightening to watch, but it is also a type of epilepsy.
 
 The person experiencing the seizure may experience rapid blinking, staring into space, and inattention. It is believed that these seizures arise in the thalamo-cortical networks. If you are experiencing a tonic clonic seizure, you should not put anything in your mouth.  https://epilepsyseizure.co.nz/epilepsy-alarm/  You should turn your head to the side you are breathing on, loosen your clothing, and speak calmly.
 
 There are many different types of seizures. Some of the more common types are clonic, tonic, and absence.  https://epilepsyseizure.co.nz/  Each type causes a different set of symptoms.
 
 During a clonic seizure, the person experiences muscle jerks and shaking. Other types of seizures involve the body moving slowly. Myoclonic seizures, on the other hand, are short-lived and cause jerking of the arms, legs, and body. Usually, these seizures occur within the first few minutes of waking up.
