Common Causes
Seizures can become life-threatening if they last too long, stop breathing, have a grand mal seizure (the strongest type of seizures in humans and animals). Seizures are treatable with medications. Treatment will depend on the severity of the seizure and any underlying cause. Upvote and follow me for more on dog topic.

It is characterized by recurrent seizures, which are brief episodes of involuntary movement that may involve a part of the body (partial) or the entire body (generalized) and are sometimes accompanied by loss of consciousness and control of bowel or bladder function.

A seizure that lasts longer than 5 minutes, or having more than 1 seizure within a 5 minutes period, without returning to a normal level of consciousness between episodes is called status epilepticus. This is a medical emergency that may lead to permanent brain damage or death.
What would cause a seizure all of a sudden?
Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure. This includes a high fever, high or low blood sugar, alcohol or drug withdrawal, or a brain concussion. But when a person has 2 or more seizures with no known cause, this is diagnosed as epilepsy.

Fever, the physical stress of being sick, and dehydration (from not drinking or eating normally, or from vomiting) can all bring on seizures. It can also be hard to get a good night's sleep while sick, and lack of sleep can be a trigger. Plus, some of the medications used to treat these ailments may be triggers.

The use or stopping of certain substances, including alcohol, may also trigger a seizure. The type of seizure depends on the cause.
Can seizures cause permanent brain damage?
Permanent neurological damage can happen after about 30 minutes of status epilepticus due to prolonged abnormal electrical activity in the affected area of the brain. Status epilepticus is a medical emergency.
Does seizures cause brain damage?
Prolonged seizures are clearly capable of injuring the brain. Isolated, brief seizures are likely to cause negative changes in brain function and possibly loss of specific brain cells.
Can having a seizure cause brain damage?
To summarize, prolonged seizures can result in brain damage, while recurring seizures can also have adverse effects on brain functioning. In turn, traumatic brain injuries can also lead to various types of seizures, which may cause further damage.
What happens if a seizure goes untreated?
If seizures can't be stopped or repeated seizures occur one right after another, permanent injury or death can occur. People with epilepsy can also die from problems that occur during or after a seizure, such as inhaling vomit. This problem can be prevented if the person is turned onto one side as soon as possible.

Seizures symptoms vary and can include a sudden change in awareness or full loss of consciousness, unusual sensations or thoughts, involuntary twitching or stiffness in the body or severe stiffening and limb shaking with loss of consciousness (a convulsion.)

What is a myoclonic seizure?
Myoclonic seizures consist of sudden body or limb jerks that can involve the arms, head and neck. The spasms occur on both sides of the body in clusters, especially in the morning. When these seizures develop in adolescence along with tonic-clonic seizures, they are part of a syndrome called juvenile myoclonic epilepsy. People can also have myoclonic seizures as part of other epilepsy related-conditions.
Why are focal seizures important?
These seizures are important to treat and prevent since they can cause respiratory problems and injuries.
Why do people have focal seizures?
Focal seizures are also called partial seizures since they begin in one area of the brain. They can be caused by any type of focal injury that leaves scar tangles. Medical history or MRI will identify a cause (such as trauma, stroke or meningitis) in about half of the people who have focal seizures. Developmental scars — ones that occur as part of fetal and early growth of the brain — are common causes of focal seizures in children.
Is epilepsy a violent disorder?
The relationship between aggressive or violent behavior and epilepsy has been extensively debated. A longstanding belief that patients with epilepsy exhibit increased aggression and are prone to violence was proposed by a number of early studies including studies noting an increased incidence of epilepsy in prisoner populations.
