A generalized tonic-clonic seizure is a seizure involving the entire body. It is also called a grand mal seizure. Such seizures usually involve muscle rigidity, violent muscle contractions, and loss of consciousness.
Generalized tonic-clonic seizures are the type of seizure that most people associate with the term "seizure," convulsion, or epilepsy. They may occur in people of any age, as a single episode, or as part of a repeated, chronic condition (epilepsy).

Alternative NamesSeizure - tonic-clonic; Seizure - grand mal; Grand mal seizure; Seizure - generalized
SymptomsMany patients have an aura (a sensory warning sign) before the seizure. This can include vision, taste, smell, or sensory changes, hallucinations, or dizziness.
The seizure itself involves:
Almost all people lose consciousness, and most people have both tonic and clonic muscle activity.
After the seizure, the person usually has:

Generalized status can preferentially manifest with tonic, clonic, absence, and/or myoclonic seizures. Hence, status can be merely a prolongation of commonly observed individual seizure types.
epilepsy
Tonic-clonic seizures end in a final generalized spasm. The affected person can lose consciousness during tonic and clonic phases of seizure.
Generalized tonic-clonic seizures are associated with drug and alcohol abuse, and low levels of blood glucose (blood sugar) and sodium. Certain psychiatric medications, antihistamines, and even antibiotics can precipitate tonic-clonic seizures.
Spreading of the epileptiform (seizure)discharge during complex partial seizures can result in secondary generalization(which means a partial seizure may spread within the brain-a process known as secondary generalization )with a tonic-clonic convulsion(generalized seizures).so yes,complex partial seizures can become generalized.The mechanism of how this happens is not fully understood in medicine but there are various explanations !!!
This sounds like a (grand mal) generalized seizure. No, they would know if they almost hit their head They have no memory of the event.
Antiseizure medications are necessary.
Yes, a Grand Mal seizure, also known as a generalized tonic-clonic seizure, can potentially be cited as a cause of death in someone who does not have epilepsy. This can occur in rare cases due to complications such as status epilepticus, which is a prolonged seizure, or sudden unexplained death in epilepsy (SUDEP), even in individuals without a prior diagnosis of epilepsy. Other underlying health conditions or triggers may also contribute to the risk of fatality from a seizure. However, such occurrences are uncommon and typically require thorough investigation to determine the exact cause.
any kind of over use of pain killers will cause pin pointed pupils. That is a major sign that over dose or a seizure is very near.
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.
seizure (medical) = hetkef (התקף) seizure (grabbing) = tfisah (תפיסה)
A generalized tonic-clonic (grand-mal) seizure begins with a loud cry before the person having the seizure loses consciousness and falls to the ground. lasts between two and five minutes. the person may be confused.when he regains consciousness.
