A "seizure" is a transient event caused by abnormal excitability of all or part of the brain. The principal cells of the brain, or "neurons", use several different types of chemicals (called neurotransmitters) to communicate with each other. These chemical messages are translated into electrical signals, which allow neurons in different parts of the brain to work together and perform tasks: to move your arm, read a book, or tell a story.

My husband was hospitalized with a seizure-like episode which was new to us. He was having what is technically called myoclonus. All of his trunk muscles were twitching (firing) and his arms were jerking and his jaw and head. His temperature was elevated and when it subsided or during the course of it he broke out in a sweat and was drenched.

The terms epilepsy and seizure are often confined. On the one hand, a seizure is the resulting behavior or set of behaviors, characterized by an apparent alteration of responsiveness and/or, sensory, or autonomic dysfunction, caused by excessive neuronal discharges in the brain. A seizure is a single event. Epilepsy is recurrent seizure activity resulting from a primary discharge of aberrant neurons within the brain. The causes of seizures are numerous.

Seizures can recur after successful epilepsy surgery in about 20-30% of patients, with times of recurrence ranging from 1 to more than 10 years. Most commonly, seizures recur after antiepileptic medications are stopped, and can be controlled again if medications are restarted. Less often, seizures recur even though the patient is still taking medications. Need an appointment?

Not usually. The overwhelming majority of seizures are either convulsions or brief alterations of consciousness during which movements are vague, non-threatening, and primitive. During these episodes, directed violence or any complex actions requiring organized thought are unlikely to occur. Clumsy, undirected violence is possible when people are restrained during a seizure, or during the period of confusion following a seizure.

Epilepsy is a chronic condition of recurrent unprovoked seizures. Isolated seizures and provoked seizures (e.g., drug or alcohol induced) are not Epilepsy even though the events are real seizures. There are many types of non-epileptic seizures. Non-epileptic seizures differ from epileptic seizures in that there is usually no evidence of abnormal electrical activity in the brain after the seizure, and they do not occur repeatedly.

Varicose veins are most commonly found on the legs of women and men who spend a lot of time on their feet. Birth control pills, hormone therapy, obesity, weight fluctuation, and constipation can also add to the development of varicose veins.

If your dog has just started on medication, be patient. It frequently takes several adjustments in medications before the right dose and combination of medications are found. If your vet has tried both Phenobarbital and bromide and your dog still doesn't have good control, you should consider asking your vet for a referral to a veterinary neurologist who may try other second and third line medications.

Left untreated seizures may get worse over time. Studies have shown that early treatment of seizures results in better long term control of seizures. With early treatment, seizures should become less frequent and less severe.

Treatment of epileptic seizures is usually accomplished through medication management. Antiepileptic medications work by circulating in the blood stream at an optimal and steady therapeutic level to provide maximum seizure control. This therapeutic level is called the plasma drug level, and this level is routinely measured from an assay of the patient's blood. Steady plasma drug levels are best achieved by taking the antiepileptic medication as prescribed.

The seizure itself is usually not painful. Following a generalized, tonic-clonic seizure, however, some children may complain of muscle aches and a sore tongue. These complaints are related to the muscle jerking and tongue biting during the seizure.

Seizures are a symptom of epilepsy. Epilepsy is the underlying tendency of the brain to produce sudden bursts of electrical energy that disrupt other brain functions. Having a single seizure does not necessarily mean a person has epilepsy. High fever, severe head injury, lack of oxygen -- a number of factors can affect the brain enough to cause a single seizure.

A person with epilepsy can help control his or her seizures by taking the prescribed medication regularly, maintaining regular sleep cycles, avoiding unusual stress, and working closely with his or her physician. Regular medical evaluation and follow-up visits are also important. However, seizures may occur even when someone is doing everything he or she is supposed to.

It's important that prescribed antiseizure medicine is taken exactly as directed. Some medications such as ethosuximide and phenobarbital can be taken once a day. Other medications must be taken several times a day to be effective. If medication in the blood is too high or too low, it can fail to control seizures or it can produce unwanted side effects, such as an increase in seizure frequency. Keeping a seizure record can also be useful for diagnosis and following the effects of new treatment.

Single brief seizures do not cause brain damage. Although tonic-clonic (grand mal) seizures, lasting longer than 20 minutes may injure the brain, there is no evidence that shorter seizures, lasting less than 20 minutes, cause permanent injury to the brain.

The overall life expectancy of people who have epilepsy EpilepsyA disorder characterized by transient but recurrent disturbances of brain function that may or may not be associated with impairment or loss of consciousness and abnormal movements or behavior.Closeis the same as for anybody else if they are otherwise pretty healthy. Some people whose epilepsy is caused by things like a stroke or a brain tumor may die sooner from those conditions, of course.

When a seizure occurs in a person who has epilepsy, and the seizure ends without injury after a minute or two, it is not usually considered a medical emergency, although the person should be asked a) if he or she has epilepsy, b) if he or she has fully recovered, and c) if he or she wants medical attention.

Epilepsy is not a mental illness. It is a temporary change in the electrical function of an otherwise normal brain. Some people with mental illness also have seizures, and some people with seizures also have mental illness, but the two conditions are not the same.

Seizures have a sudden beginning, a progression of symptoms, and a gradual recovery. Intoxication begins slowly and takes much longer to subside. Sometimes an intoxicated person will have a seizure, in which case there will be a strong odor of alcohol in addition to the seizure-cased behavior. In that case, the seizure will resolve, but return to full consciousness will not be as obvious. Whatever the cause, the seizure needs to be handled appropriately.

I am not aware of any evidence that seizures improve patients but it IS a sign of activity and therefore they may be a sign of recovery. Note that seizures may result from the withdrawal of drugs e.g. baclofen Ref Barker I, Grant IS. Convulsions after abrupt withdrawal of baclofen. Lancet 1982;ii:556-7. He also asked if when I recommended in my post that oxygen should be given post seizure if I meant be under hyperbaric conditions. Oxygen given immediately at high flow (i.e.

This is a natural process. If it occurs more often, with equal or bigger icebergs, perhaps then we can say more about what is causing this that isn't the natural part of the hydrological cycle, which is for snow to fall over Antarctica, and the continually forming icecap to slowly increase, move out to sea, and calve off icebergs.

You should consult your doctor. Usually, side effects are well tolerated. In some cases, your physician will direct you to use less RENOVA, decrease the frequency of application, increase the use of moisturizers, discontinue use temporarily or discontinue use altogether. RENOVA should only be used under medical supervision as part of a total skin care and sun protection program.

The overwhelming majority of abortions are performed in the first trimester of pregnancy. The Centers for Disease Control estimates that 58 percent of legal abortions occur within the first eight weeks of gestation, and 88 percent are performed within the first 12 weeks (based on the most recent data from 2000). Just over 10 percent are performed between 13 and 20 weeks. Less than one-half-of-one percent occur after 24 weeks.

CWD is relatively rare. In Colorado, for example, fewer than 200 cases, mostly in mule deer, have been documented since 1981. In checking hunter-harvested animals, less than 6% of deer and 1% of elk in north-central and northeastern Colorado were found to have CWD. Similar surveillance in southeastern Wyoming also indicated that less than 7% of deer had CWD. Deer and elk checked outside these areas in Colorado and Wyoming did not have CWD.
