Tonic seizures commonly occur during non-rapid eye movement (non-REM) sleep and drowsiness.
Tonic clonic seizures are the most common type of seizures. They can be dangerous to the sufferers of seizures because they could hurt themselves or choke while undergoing a seizure.
No. Seizures can be 'grand mal' which involve the tonic-clonic muscle movement you describe as convulsions. 'Petit mal' seizures can be absence seizures, most often seen in children, where the patient seems catatonic for a brief period. Partial seizures can involve only one small body area, and some seizures consist of just a recurrent tic which can evolve into a larger seizure. Even a hiccup is believed to be a type of mild seizure.

Eclampsia is a complication of pregnancy where the patient has tonic clonic seizures. It is most common in the third trimester of pregnancy. It may occur up to 6 weeks after pregnancy, in the period of time called the puerperium, during which the changes that occur during pregnancy regress back to the pre-pregnant state.
Myoclonic seizures are characterized by brief, involuntary spasms of the tongue or muscles of the face, arms, or legs. Myoclonic seizures are most apt to occur when waking after a night's sleep.
Chill tonic was a tonic containing quinine and other ingredients to battle the symptoms (often chills) of malaria. The most famous (and perhaps the first?) chill tonic was "Grove's Tasteless Chill Tonic," in which the flavor of quinine supposedly could not be tasted.
This type of seizure many people think of when they hear the word epilepsy. Marked by loss of consciousness and stiffening and/or jerking of the muscles throughout the body, including arms and legs, these seizures are often referred to as grand mal seizures. The term tonic-clonic refers to certain kinds of body movements that appear during the seizures. Tonic means sudden stiffening of the limbs; clonic refers to rhythmic jerking.
The types of seizures often change. In most cases, the drop seizures subside. They are replaced by partial, complex partial, and secondarily generalized convulsions.
There is temporal lobe epilepsy (which is the most common), frontal lobe epilepsy, parietal lobe epilepsy, and occipital lobe epilepsy. however, seizures are catagorized into two catagories: focal seizures and generalized seizures.
Convulsions, or seizures, typically last from a few seconds to a few minutes. Most generalized tonic-clonic seizures last between 1 to 3 minutes, while focal seizures may be shorter. If a seizure lasts longer than 5 minutes, it is considered a medical emergency known as status epilepticus and requires immediate attention. Always consult a medical professional for specific concerns regarding seizures.

Seizures are not a common symptom in influenza, however, they can accompany a high fever, such as often occurs with the flu. These are called febrile seizures. Children are most vulnerable to febrile seizures. However, do not assume this is just a symptom of the flu if there are seizures, all seizures should be evaluated immediately by a physician to determine the type, cause, and need for treatment.
