Topic: Epileptic seizures


  
  Seizure - Wikipedia, the free encyclopedia
However, a seizure can also be as subtle as marching numbness of a part of body, a brief loss of memory, sparkling of flashes, sniffing an unpleasant odor, a strange epigastric sensation or a sensation of fear.
Seizures are often associated with epilepsy and related seizure disorders, although head trauma, intoxication, infection, metabolic disturbances, withdrawal symptoms (from sedatives such as alcohol, barbiturates and benzodiazepines) and space-occupying processes in the brain (abscesses, tumors) may also cause them.
It is still disputable whether febrile seizures have to be regarded as an epileptic disorder or not; the dispute hinges on whether fever is considered a provocant.

 Epilepsy - Wikipedia, the free encyclopedia
Epileptic seizures are classified both by their patterns of activity in the brain and their effects on behaviour.
Epileptic seizures may occur in any person under certain circumstances, including acute illness and drug overdoses, but these provoked seizures are not part of the definition of epilepsy.
In most cases, the proper emergency response to a generalized tonic-clonic epileptic seizure is simply to prevent the patient from self-injury by moving him or her away from sharp edges, placing something soft beneath the head, and carefully rolling the person onto his or her side to avoid asphyxiation.

 NSE : Information on epilepsy: Non-epileptic seizures
The term 'seizure' describes a sudden, short event where there is a change in a person's awareness of where they are or what they are doing, their behaviour or their feelings.
Epileptic seizures are caused by a sudden, brief interruption in the way the brain is working.
These seizures are sometimes called 'pseudoseizures' but this term is unhelpful as it suggests that the person is not having real seizures or that the seizures are 'put on'.

 NSE : Epilepsy: Information on seizures and status epilepticus
When naming seizures, it is important to use terms which describe what is happening during the seizure and to avoid terms such as 'mild' or 'major' which do not describe the event.
The seizure may be confined to either rhythmical twitching of one limb or part of a limb, or to unusual tastes or sensations such as pins and needles in a specific part of the body.
Complex partial seizures most often involve the temporal lobes of the brain, in which case the person may be said to have 'temporal lobe epilepsy', however they can also affect the frontal, parietal and occipital lobes.

 Seizure Disorders In Childhood   (Site not responding. Last check: 2007-10-08)
Childhood seizures represent paroxysmal clinical events characterized by abnormal, excessive discharges originating from populations of cortical neurons and resulting in some clinically evident alteration of function or behavior.
Generalized seizures are thought to originate within the brain in a bilaterally symmetric fashion at onset.
Complex partial seizures may produce similar sensory, motor, or autonomic symptoms, but are also characterized by some impairment or alteration of consciousness during the event.

Mirroring is when a seizure focus occurs in one side of the brain and then an identical site occurs in the other side of the brain after several seizures.
Kindling is when the seizure focus in the brain develops strong enough pathways that it makes it easier for the seizure to occur -- almost as if the brain "learns" to seizure.
It is possible that by controlling seizures quickly through the use of medications that these effects could be stopped and that may lessen the amount or duration of need for seizure control medications.

True seizures, also called epileptic seizures, are caused by the sudden, uncontrolled discharge of a group of neurons in the cerebral cortex.
An epileptic seizure can be triggered by a single event, or may be due to a chronic tendency (diathesis) to cause seizures.
The seizures must be terminated as rapidly as possible to prevent permanent brain damage as well as death from hypoxia, acidosis, rhabdomyolysis, and secondary renal damage.

 Full moon does not influence the frequency of epileptic seizures
Werewolves notwithstanding, the full moon does not influence the frequency of epileptic seizures, reports a University of South Florida study.
Benbadis said he decided to investigate the possible relationship between phases of the moon and the frequency of seizures after repeatedly hearing patients claim that their seizures were triggered or worsened by the full moon.
The researchers divided the seizures into epileptic seizures, those caused by electrical disruptions in the brain, and psychogenic nonepileptic seizures, those that are not caused by brain electrical disruptions and tend to be emotional.

 Epileptic Seizures Triggered Directly by Focal Transcranial Magnetic Stimulation.
Two seizures were attributed to TMS since both were induced exclusively by the figure-8-shaped coil and their beginning could be documented by tonic EMG activity following the evoked early response.
He had a breakthrough seizure this weekend so the neurologist switched him to a capsule version of the XR which apparently is easier for some people to breakdown.
My son used to have probably one seizure per year until recently (due to puberty) if your child starts having more seizures as they grow it is probably due to the rate of growth and the changes that are occuring in their body chemistry.

 Underlying Causes for Seizures
Seizures are common and may initially be the only sign.
Whenever an older dog begins to have seizures, and causes such as toxins, trauma and diabetes have been ruled out, the possibility of a brain stumor hould be considered.
Although seizures are one of the most alarming symptoms of a brain tumor, there are others that may give additional indications of a tumor's presence.

 New Blood Test May Detect Epileptic Seizures
Researchers reviewed all of the published studies on the prolactin blood test and found it may be useful in certain situations in determining whether an epileptic seizure occurred in adults and older children with unexplained seizures.
Researchers say epileptic seizures are thought to affect the hypothalamus and may alter the release of prolactin, causing levels of the hormone to rise.
Researchers found the test was useful at differentiating epileptic seizures from those caused by mental problems.

 SPACE.com -- Full Moon Not to Blame for Epileptic Seizures
"Contrary to the myth, epileptic seizures are not more common during a Full Moon," said Selim Benbadis, associate professor of neurology and neurosurgery at the university's College of Medicine.
Of the epileptic seizures, 152 occurred during the Moon's Last Quarter and 94 when Earth's natural satellite was full.
Its seizures were once pinned on witchcraft and possession by demons, Benbadis notes.

 News - Non-Epileptic Seizures Have Root In Abusive Past
Self-reports of seizures were highly correlated with paranoid ideation, and both dissociative phenomena and a history of sexual abuse was common among the patients.
When patients were told by their health care providers that their seizures were not true epileptic events, they experienced a resurgence of the feelings they had associated with not being believed when they reported being sexually abused as children.
According to the authors, the presence of non-epileptic seizures appears to be associated with continually being in abusive or exploitative relationships for which the patients could not perceive an escape or solution.

 Dogs may predict epileptic seizures in children   (Site not responding. Last check: 2007-10-08)
New Canadian research suggests that your canine friend may be able to predict epileptic seizures in children a few hours in advance.
It was found that before a seizure the dog tended to lick the child's face, act in a protective manner or whimper.
The researchers could not be sure how the dogs recognised or anticipated epileptic seizures, but speculated that the dogs may of been able to recognise subtle visual clues or particular smells leading up to a seizure.

 Epileptic seizures can be anticipated by non-linear analysis - Nature Medicine
Epileptic seizures are a principal brain dysfunction with important public health implications, as they affect 0.8% of humans.
The ability to anticipate the onset of seizures in such cases would permit clinical interventions.
We demonstrate that in most cases (17 of 19), seizure onset could be anticipated well in advance (between 2−6 minutes beforehand), and that all subjects seemed to share a similar 'route' towards seizure.

 Epileptic seizures, Eastern Carolina   (Site not responding. Last check: 2007-10-08)
An epileptic seizure is the body and brain's response to sudden bursts of abnormal electrical activity in the brain.
While the cause of these seizures is not always clear, they often result from severe head injury, stroke, brain tumor, brain infections, scar tissue, and other diseases that affect the brain.
Partial seizures are usually treated with medications, although surgery to remove the affected area of the brain or interrupt certain pathways is an option for some people.

The criterion for psychogenesis was the reversal of the amnesia, which is often present in epileptic- and pseudo-epileptic seizures.
As pseudo-epileptic seizures can be characterized by their dissociative nature, a reasonable hypothesis is that patients with pseudo-epileptic seizures are more responsive to hypnosis than patients with epileptic seizures.
Measurements of hypnotizability among seven patients with epileptic seizures and six patients with pseudo-epileptic seizures supported this supposition.

These seizure-alerting dogs may reduce frequency of epileptic seizures, improving the families' quality of life, he explains.
The typical response was licking the child's face, protecting the child, and whimpering; the dogs were never aggressive or harmed the child.
Sometimes the seizure alert behavior was just 10 seconds before the epileptic seizure; in other cases, the alert came up to five hours before.

 Full moon exerts no pull on frequency of epileptic seizures - Epilepsy : Epilepsy.com
Contrary to the myth, epileptic seizures are not more common during a full moon, said Selim Benbadis, MD, associate professor of neurology and neurosurgery at the USF College of Medicine.
In fact, we found the number of epileptic seizures was lowest during the full moon and highest in the moon's last quarter.
In the past, before physicians recognized that epilepsy was caused by processes in a person's own body, the disease's frightening seizures were associated with demonic possession and witchcraft, Benbadis said.

 News - Outpatient Diagnosis Of Non-Epileptic Seizures
Habitual non-epileptic seizures can be reliably recorded during short outpatient video electroencephalograph (EEG) in selected patients using simple suggestion techniques.
The suggestion techniques appear to increase the yield of recorded seizures, particularly in the subgroup of patients with a history of previous events in medical settings.
Thirty patients with a probable clinical diagnosis of non-epileptic seizures were randomized to receive either "suggestion" or "no suggestion" during video EEG recording at a regional, tertiary care epilepsy centre.

 Shocks keep epileptic seizures at bay
The device, implanted into the epileptic woman’s chest, has helped bring her once frequent seizures under control.
VNS Therapy uses a device similar to a pacemaker to prevent seizures by sending mild pulses of electrical energy to the brain via the vagus nerve in the neck.
The shocks are believed to condition the brain to react better to the interruptions in brain function that are common during seizures, according to the Epilepsy Treatment Center.

 Efficacy of a 1- to 3-day ambulatory EEG in recording epileptic seizures   (Site not responding. Last check: 2007-10-08)
The duration of an ambulatory electroencephalogram (aEEG) necessary to record epileptic seizures was studied in neurological patients.
Of the total number of epileptic seizures, 81% were encountered during the first 24 hours, an additional 10% during the next 24 hours, and 7% during the third 24-hour period.
Our conclusion was that, in patients exhibiting epileptic seizures during the aEEG recording, the diagnosis will be confirmed by a 2-day recording in the vast majority of the cases.
