What is tonic-clonic?

Tonic-clonic refers to a type of seizure characterized by two phases: the tonic phase and the clonic phase.

- Tonic phase: The tonic phase is characterized by a sudden stiffening of the body and a loss of consciousness. The person may also experience a clenching of the teeth, dilation of the pupils, and a rapid heart rate. This phase typically lasts for about 10-20 seconds.

- Clonic phase: The clonic phase is characterized by rhythmic jerking movements of the limbs and body. The person may also experience foaming at the mouth and loss of bladder control. This phase typically lasts for about 30-60 seconds.

Tonic-clonic seizures are the most common type of seizure, and they can occur in people of all ages. However, they are more common in children and young adults. Tonic-clonic seizures can be caused by a variety of factors, including epilepsy, head trauma, stroke, and drug use.

Treatment for tonic-clonic seizures typically involves taking anti-seizure medication. In some cases, surgery may be necessary to control the seizures.
