In 1999, Sachdeo and colleagues at the University of Medicine and Dentistry of New Jersey and the Robert Wood Johnson Medical School in New Brunswick reported that 33% of the patients in a group of patients taking topiramate experienced a minimum 50% reduction in seizures (specifically drop attacks and tonic–clonics), compared with 8% in the placebo group. It was also found to be effective as an adjunctive therapy in a review published by Drs. Edith Alva Moncayo and Antonio Ruiz Ruiz in March 2003.

Motte reported in 1997 that lamotrigine was effective in the treatment of LGS, with the most common side effect in the treatment group relative to placebo being colds or viral illnesses. Two years later, it was approved by Health Canada for adjunctive therapy in Lennox Gastaut in adults and children. The United States Food and Drug Administration approved it for that in August 1998.

Felbamate is indicated in the use of LGS in the event that everything else fails, and was found to be superior to placebo in controlling treatment resistant partial seizures and atonic seizures. However, it has been known to cause aplastic anemia and liver toxicity.

No high quality evidence has shown any drug very useful as of 2013. Rufinamide, lamotrigine, topiramate and felbamate may be useful.

Seizures in cats are caused by various onsets. Cats can have reactive, primary (idiopathic) or secondary seizures. Idiopathic seizures are not as common in cats as in dogs however a recent study conducted showed that of 91 feline seizures, 25% were suspected to have idiopathic epilepsy. In the same group of 91 cats, 50% were secondary seizures and 20% reactive.

The lack of generally recognized clinical recommendations available are a reflection of the dearth of data on the effectiveness of any particular clinical strategy, but on the basis of present evidence, the following may be relevant:

- Epileptic seizure control with the appropriate use of medication and lifestyle counseling is the focus of prevention.

- Reduction of stress, participation in physical exercises, and night supervision might minimize the risk of SUDEP.

- Knowledge of how to perform the appropriate first-aid responses to seizure by persons who live with epileptic people may prevent death.

- People associated with arrhythmias during seizures should be submitted to extensive cardiac investigation with a view to determining the indication for on-demand cardiac pacing.

- Successful epilepsy surgery may reduce the risk of SUDEP, but this depends on the outcome in terms of seizure control.

- The use of anti suffocation pillows have been advocated by some practitioners to improve respiration while sleeping, but their effectiveness remain unproven because experimental studies are lacking.

- Providing information to individuals and relatives about SUDEP is beneficial.

Though there is limited evidence, outcomes appear to be relatively poor with a review of outcome studies finding that two thirds of PNES patients continue to experience episodes and more than half are dependent on social security at three-year followup. This outcome data was obtained in a referral-based academic epilepsy center and loss to follow-up was considerable; the authors point out ways in which this may have biased their outcome data. Outcome was shown to be better in patients with higher IQ, social status, greater educational attainments, younger age of onset and diagnosis, attacks with less dramatic features, and fewer additional somatoform complaints.

Continuous prophylactic antiepileptic drug (AED) treatment may not be needed particularly for children with only 1-2 or brief seizures. This is probably best reserved for children whose seizures are unusually frequent, prolonged, distressing, or otherwise significantly interfering with the child’s life. There is no evidence of superiority of monotherapy with any particular common AED.

Autonomic status epilepticus in the acute stage needs thorough evaluation for proper diagnosis and assessment of the neurologic/autonomic state of the child. "Rescue" benzodiazepines are commonly used to terminate it. Aggressive treatment should be avoided because of the risk of iatrogenic complications, including cardiovascular arrest. There is some concern that intravenous lorazepam and/or diazepam may precipitate cardiovascular arrest. Early parental treatment is more effective than late emergency treatment. Buccal midazolam is probably the first choice medication for out of hospital termination of autonomic status epilepticus which should be administered as soon as the child shows evidence of onset of its habitual autonomic seizures.

Parental education about Panayiotopoulos syndrome is the cornerstone of correct management. The traumatizing, sometimes long-lasting effect on parents is significant particularly because autonomic seizures may last for many hours compounded by physicians’ uncertainty regarding diagnosis, management, and prognosis.

Many antiepileptic drugs are used for the management of canine epilepsy. Oral phenobarbital, in particular, and imepitoin are considered to be the most effective antiepileptic drugs and usually used as ‘first line’ treatment. Other anti-epileptics such as zonisamide, primidone, gabapentin, pregabalin, sodium valproate, felbamate and topiramate may also be effective and used in various combinations. A crucial part of the treatment of pets with epilepsy is owner education to ensure compliance and successful management.

Seven anti-epileptic drugs are approved for use in cases of suspected primary generalized epilepsy:

- Felbamate

- Levetiracetam

- Zonisamide

- Topiramate

- Valproate

- Lamotrigine

- Perampanel

Valproate, a relatively old drug, is often considered the first-line treatment. It is highly effective, but its association with fetal malformations when taken in pregnancy limits its use in young women.

All anti-epileptic drugs (including the above) can be used in cases of partial seizures.

Prevention of PTE involves preventing brain trauma in general; protective measures include bicycle helmets and child safety seats. No specific treatment exists to prevent the development of epilepsy after TBI occurs. In the past, antiepileptic drugs were used with the intent of preventing the development of PTE. However, while antiepileptic drugs can prevent early PTS, clinical studies have failed to show that prophylactic use of antiepileptic drugs prevents the development of PTE. Why antiepileptic drugs in clinical trials have failed to stop PTE from developing is not clear, but several explanations have been offered. The drugs may simply not be capable of preventing epilepsy, or the drug trials may have been set up in a way that did not allow a benefit of the drugs to be found (e.g. drugs may have been given too late or in inadequate doses). Animal studies have similarly failed to show much protective effect of the most commonly used seizure medications in PTE trials, such as phenytoin and carbamazepine. Antiepileptic drugs are recommended to prevent late seizures only for people in whom PTE has already been diagnosed, not as a preventative measure. On the basis of the aforementioned studies, no treatment is widely accepted to prevent the development of epilepsy. However, it has been proposed that a narrow window of about one hour after TBI may exist during which administration of antiepileptics could prevent epileptogenesis (the development of epilepsy).

Corticosteroids have also been investigated for the prevention of PTE, but clinical trials revealed that the drugs did not reduce late PTS and were actually linked to an increase in the number of early PTS.

As of 2017, data on optimal treatment was limited. Therapies with hormones is the standard of care, namely adrenocorticotrophic hormone (ACTH), or oral

corticosteroids such as prednisone. Vigabatrin is also a common consideration, though there is a risk of visual field loss with long term use. The high cost of ACTH leads doctors to avoid it in the US; higher dose prednisone appears to generate equivalent outcomes.

As of 2017 data from clinical trials of the ketogenic diet for treating infantile spams was inconsistent; most trials were as a second-line therapy after failure of drug treatment, and as of 2017 it had not been explored as a first line treatment in an adequately designed clinical trial.

The cause of FIRES is not known. It does not happen twice in the same family, but the medical community does not know if it is genetic. It happens in boys more than girls. After the initial status, life expectancy is not affected directly. Issues such as overdose of medications or infections at a food tube site are examples of things that would be secondary to the status.

Like other forms of epilepsy, nocturnal epilepsy can be treated with anti-convulsants.

Despite the effectiveness of anti-convulsants in people who suffer from nocturnal epilepsy, the drugs are shown to disrupt a person's sleeping structure. This may cause concern in people who suffer specifically from nocturnal epilepsy because undisrupted sleep is important for these people, as it lowers the likeliness of epileptic symptoms to arise.

One particular study by V. Bradley and D. O'Neill analysed the different forms of epilepsy, including nocturnal epilepsy and its relationship with sleep. They found that some patients only experienced epileptic symptoms while they are asleep (nocturnal epilepsy), and that maintaining good sleep helped in reducing epileptic symptoms. Another study determined that anti-convulsant medications can minimize epilepsy not just in people who are awake, but also in people who are asleep. However, some of these anti-convulsant medications did also have adverse effects on subjects' sleeping structures, which can exacerbate epileptic symptoms in people who suffer from nocturnal epilepsy.

To minimize epileptic seizures in these people, it is important to find an anti-convulsant medication that does not disrupt a person's sleeping structure. The anti-convulsant medications that were tested to meet this criteria are: phenobarbital, phenytoin, carbamazepine, valproate, ethosuximide, felbamate, gabapentin, lamotrigine, topiramate, vigabatrin, tiagabine, levetiracetam, zonisamide, and oxcarbazepine. Oxcarbazepine is shown to have the least amount of adverse effects on sleep. Another study shows that it enhances slow wave-sleep and sleep continuity in patients with epilepsy.

A number of measures have been attempted to prevent seizures in those at risk. Following traumatic brain injury anticonvulsants decrease the risk of early seizures but not late seizures.

In those with a history of febrile seizures, medications (both antipyretics and anticonvulsants) have not been found effective for prevention. Some, in fact, may cause harm.

There is no clear evidence that antiepileptic drugs are effective or not effective at preventing seizures following a craniotomy, following subdural hematoma, after a stroke, or after subarachnoid haemorrhage, for both people who have had a previous seizure, and those who have not.

At the hospital, physicians follow standard protocol for managing seizures. Cluster seizures are generally controlled by benzodiazepines such as diazepam, midazolam, lorazepam or clonazepam. The use of oxygen is recommended in the United States, but in Europe it is only recommended in cases of prolonged epileptic status.

Antiepileptic drugs (AEDs) are used in most cases to control seizures, however, PCDH19 gene-related epilepsy is generally associated with early-onset development of drug resistant seizures. Existing data supports the use of “rational polypharmacy,” which consists of a step-wise addition of AEDs until a patient responds favorably or experiences intolerable adverse events. In general, as in other types of uncontrolled epilepsy, the use of drugs with different mechanisms of action appears to be more effective than combining drugs with similar mechanisms of action.

No currently marketed AEDs have been extensively studied in PCDH19 gene-related epilepsy and there is no established treatment strategy for girls diagnosed with PCDH19 gene-related epilepsy. Patients may respond well to treatment with levetiracetam and in cases of drug resistance, stiripentol, which is not approved in the U.S. but is available through the FDA Expanded Access IND process.

Antiepileptic drugs may be given to prevent further seizures; these drugs completely eliminate seizures for about 35% of people with PTE. However, antiepileptics only prevent seizures while they are being taken; they do not reduce the occurrence once the patient stops taking the drugs. Medication may be stopped after seizures have been controlled for two years. PTE is commonly difficult to treat with drug therapy, and antiepileptic drugs may be associated with side effects. The antiepileptics carbamazepine and valproate are the most common drugs used to treat PTE; phenytoin may also be used but may increase risk of cognitive side effects such as impaired thinking. Other drugs commonly used to treat PTE include clonazepam, phenobarbitol, primidone, gabapentin, and ethosuximide. Among antiepileptic drugs tested for seizure prevention after TBI (phenytoin, sodium valproate, carbamazepine, phenobarbital), no evidence from randomized controlled trials has shown superiority of one over another.

People whose PTE does not respond to medication may undergo surgery to remove the epileptogenic focus, the part of the brain that is causing the seizures. However surgery for PTE may be more difficult than it is for epilepsy due to other causes, and is less likely to be helpful in PTE than in other forms of epilepsy. It can be particularly difficult in PTE to localize the epileptic focus, in part because TBI may affect diffuse areas of the brain. Difficulty locating the seizure focus is seen as a deterrent to surgery. However, for people with sclerosis in the mesial temporal lobe (in the inner aspect of the temporal lobe), who comprise about one third of people with intractable PTE, surgery is likely to have good outcome. When there are multiple epileptic foci or the focus cannot be localized, and drug therapy is not effective, vagus nerve stimulation is another option for treating PTE.

People with PTE have follow-up visits, in which health care providers monitor neurological and neuropsychological function and assess the efficacy and side effects of medications. As with sufferers of other types of epilepsy, PTE sufferers are advised to exercise caution when performing activities for which seizures could be particularly risky, such as rock climbing.

Panayiotopoulos syndrome probably affects 13% of children aged 3 to 6 years who have had 1 or more afebrile seizures and 6% of such children in the 1- to 15-year age group. All races and both sexes are affected.

There have been early and consistent strategies for measurement to better understand vertiginous epilepsy including caloric reflex test, posture and gait, or rotational experimentation.

In Japan, Kaga et al prepared a longitudinal study of rotation tests comparing congenital deafness and children with delayed acquisition of motor system skills. They were able to demonstrate the development of post-rotation nystagmus response from the frequency of beat and duration period from birth to six years to compare to adult values. Overall, the study demonstrated that some infants from the deaf population had impaired vestibular responses related to head control and walking age. A side interpretation included the evaluation of the vestibular system in reference to matching data with age.

Research in this area of medicine is limited due to its lacking need for urgent attention. But, the American Hearing Research Foundation (AHRF) conducts studies in which they hope to make new discoveries to help advance treatment of the disease and possibly one day prevent vertiginous seizures altogether.

Unfortunately, there is no real way to prevent against vertiginous episodes out of the means of managing the disease. As head trauma is a major cause for vertiginous epilepsy, protecting the head from injury is an easy way to avoid possible onset of these seizures. With recent advances in science it is also possible for an individual to receive genetic screening, but this only tells if the subject is predisposed to developing the condition and will not aid in preventing the disease.

There is a range of ways to manage vertiginous epilepsy depending on the severity of the seizures. For simple partial seizures medical treatment is not always necessary. To the comfort of the patient, someone ailed with this disease may be able to lead a relatively normal life with vertiginous seizures. If, however, the seizures become too much to handle, antiepileptic medication can be administered as the first line of treatment. There are several different types of medication on the market to deter epileptic episodes but there is no support to show that one medication is more effective than another. In fact, research has shown that simple partial seizures do not usually respond well to medication, leaving the patient to self-manage their symptoms. A third option for treatment, used only in extreme cases when seizure symptoms disrupt daily life, is surgery wherein the surgeon will remove the epileptic region.

It is not possible to make a generalised prognosis for development due to the variability of causes, as mentioned above, the differing types of symptoms and cause. Each case must be considered individually.

The prognosis for children with idiopathic West syndrome are mostly more positive than for those with the cryptogenic or symptomatic forms. Idiopathic cases are less likely to show signs of developmental problems before the attacks begin, the attacks can often be treated more easily and effectively and there is a lower relapse rate. Children with this form of the syndrome are less likely to go on to develop other forms of epilepsy; around two in every five children develop at the same rate as healthy children.

In other cases, however, treatment of West syndrome is relatively difficult and the results of therapy often dissatisfying; for children with symptomatic and cryptogenic West syndrome, the prognosis is generally not positive, especially when they prove resistant to therapy.

Statistically, 5 out of every 100 children with West syndrome do not survive beyond five years of age, in some cases due to the cause of the syndrome, in others for reasons related to their medication. Only less than half of all children can become entirely free from attacks with the help of medication. Statistics show that treatment produces a satisfactory result in around three out of ten cases, with only one in every 25 children's cognitive and motoric development developing more or less normally.

A large proportion (up to 90%) of children suffer severe physical and cognitive impairments, even when treatment for the attacks is successful. This is not usually because of the epileptic fits, but rather because of the causes behind them (cerebral anomalies or their location or degree of severity). Severe, frequent attacks can (further) damage the brain.

Permanent damage often associated with West syndrome in the literature include cognitive disabilities, learning difficulties and behavioural problems, cerebral palsy (up to 5 out of 10 children), psychological disorders and often autism (in around 3 out of 10 children). Once more, the cause of each individual case of West syndrome must be considered when debating cause and effect.

As many as 6 out of 10 children with West syndrome suffer from epilepsy later in life. Sometimes West syndrome turns into a focal or other generalised epilepsy. Around half of all children develop Lennox-Gastaut syndrome.

Potentially sharp or dangerous objects should be moved from the area around a person experiencing a seizure, so that the individual is not hurt. After the seizure if the person is not fully conscious and alert, they should be placed in the recovery position. A seizure longer than five minutes is a medical emergency known as status epilepticus. Contrary to a common misconception, bystanders should not attempt to force objects into the mouth of the person suffering a seizure, as doing so may cause injury to the teeth and gums.

Most generalized epilepsy starts during childhood. While some patients outgrow their epilepsy during adolescence and no longer need medication, in others, the condition remains for life, thereby requiring lifelong medication and monitoring.

No single cause of OS has been identified. In most cases, there is severe atrophy of both hemispheres of the brain. Less often, the root of the disorder is an underlying metabolic syndrome. Although it was initially published that no genetic connection had been established, several genes have since associated with Ohtahara syndrome. It can be associated with mutations in "ARX", "CDKL5", "SLC25A22", "STXBP1", "SPTAN1", "KCNQ2", "ARHGEF9", "PCDH19", "PNKP", "SCN2A", "PLCB1", "SCN8A", and likely others.

Treatment outlook is poor. Anticonvulsant drugs and glucocorticoid steroids may be used to try to control the seizures, but their effectiveness is limited. Most therapies are related to symptoms and day-to-day living.

Since migralepsy is, for all intents and purposes, a combination of migraines and epilepsy, the medication for the conditions supplied individually can be combined jointly in order to lessen the effects of both. It is also helpful that many antiepileptic drugs also work as antimigraines, lessening the number of medications that must be taken. Thus, while neither can be cured, they can be treated so that they occur less frequently and allow a patient to live a relatively normal life.

There are a number of recommended steps to explain to people their diagnosis in a sensitive and open manner. A negative diagnosis experience may cause frustration and could cause a person to reject any further attempts at treatment. Ten points recommended to explain the diagnosis to the person and their caregivers are:

1. Reasons for concluding they do not have epilepsy

2. What they do have (describe dissociation)

3. Emphasise they are not suspected of "putting on" the attacks

4. They are not 'mad'

5. Triggering "stresses" may not be immediately apparent.

6. Relevance of aetiological factors in their case

7. Maintaining factors

8. May improve after correct diagnosis

9. Caution that anticonvulsant drug withdrawal should be gradual

10. Describe psychological treatment

Psychotherapy is the most frequently used treatment, which might include cognitive behavioral therapy, insight-orientated therapy, and/or group work. There is some tentative evidence supporting selective serotonin reuptake inhibitor antidepressants.
