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.

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.

Like other forms of epilepsy, abdominal epilepsy is treated with anticonvulsant drugs, such as phenytoin. Since no controlled studies exist, however, other drugs may be equally effective.

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.

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 is no benefit from the use of phenytoin, valproate, pyridoxine, ibuprofen, zinc sulfate, diclofenac, acetaminophen.

There is a decrease of recurrent febrile seizures with intermittent diazepam and phenobarbital but there is a high rate of adverse effects. They are thus not recommended as an effort to prevent further seizures.

No cure is available for PSE, although the sensitivity of some patients may diminish over time. Medical treatment is available to reduce sensitivity, with sodium valproate being commonly prescribed. Patients can also learn to avoid situations in which they might be exposed to stimuli that trigger seizures and/or take steps to diminish their sensitivity (as by covering one eye) if they are unavoidably exposed. These actions together can reduce the risk of seizures to almost zero for many PSE patients.

Some PSE patients have trigger stimuli that are so specific that they are never likely to encounter them in real life. Their PSE may only be discovered by accident in an unusual situation or during examination for other complaints.

The prognosis of ICOE-G is unclear, although available data indicate that remission occurs in 50–60% of patients within 2–4 years of onset. Seizures show a dramatically good response to carbamazepine in more than 90% of patients. However, 40–50% of patients may continue to have visual seizures and infrequent secondarily generalized convulsions, particularly if they have not been appropriately treated with antiepileptic drugs.

Patients with ICOE-G need prophylactic treatment mainly with carbamazepine or other antiepileptic drugs licensed for focal seizures. A slow reduction in the dose of medication 2 or 3 years after the last visual or other minor or major seizure should be advised, but if visual seizures reappear, treatment should be restored.

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.

It is important that parents and caretakers remain calm, take first aid measures, and carefully observe the child. If a child is having a febrile seizure, parents and caregivers should do the following:

- Note the start time of the seizure. If the seizure lasts longer than 5 minutes, call an ambulance. The child should be taken immediately to the nearest medical facility for diagnosis and treatment.

- Call an ambulance if the seizure is less than 5 minutes but the child does not seem to be recovering quickly.

- Gradually place the child on a protected surface such as the floor or ground to prevent accidental injury. Do not restrain or hold a child during a convulsion.

- Position the child on his or her side or stomach to prevent choking. When possible, gently remove any objects from the child’s mouth. Nothing should ever be placed in the child's mouth during a convulsion. These objects can obstruct the child's airway and make breathing difficult.

- Seek immediate medical attention if this is the child’s first febrile seizure and take the child to the doctor once the seizure has ended to check for the cause of the fever. This is especially urgent if the child shows symptoms of stiff neck, extreme lethargy, or abundant vomiting, which may be signs of meningitis, an infection over the brain surface.

In those who have prolonged seizures intravenous lorazepam is recommended. The other benzodiazepines—midazolam and diazepam—are also reasonable options.

When functioning correctly, mains-powered fluorescent lighting has a flicker rate sufficiently high (twice the mains frequency, typically 100 Hz or 120 Hz) to reduce the occurrence of problems. However, a faulty fluorescent lamp can flicker at a much lower rate and trigger seizures. Newer high-efficiency compact fluorescent lamps (CFL) with electronic ballast circuits operate at much higher frequencies (10–20 kHz) not normally perceivable by the human eye, though defective lights can still cause problems.

The Job Accommodation Network lists reduction or elimination of fluorescent lighting as an appropriate accommodation for many conditions including epilepsy. The Canadian Department of Labour states that the newer lights are problematic for fewer people.

The International League Against Epilepsy (ILAE) define an epileptic seizure as "a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain." Epileptic seizures can occur in someone who does not have epilepsy – as a consequence of head injury, drug overdose, toxins, eclampsia or febrile convulsions, for example.

Medically, when used on its own, the term seizure implies an epileptic seizure. The lay use of this word can also include sudden attacks of illness, loss of control, spasm or stroke. Where the physician is uncertain as to the diagnosis, the medical term paroxysmal event and the lay terms spells, funny turns or attacks may be used.

Possible causes include:

- Syncope (fainting)

- Reflex anoxic seizures

- Breath-holding spells of childhood

- Hypoglycaemia

- Cataplexy

- Hyperekplexia, also called startle syndrome

- Migraine

- Narcolepsy

- Non-epileptic myoclonus

- Opsoclonus

- Parasomnias, including night terrors

- Paroxysmal kinesigenic dyskinesia

- Repetitive or ritualistic behaviours

- Tics

- AADC Deficiency

Most children who develop epilepsy are treated conventionally with anticonvulsants. In about 70% of cases of childhood epilepsy, medication can completely control seizures. Unfortunately, medications come with an extensive list of side effects that range from mild discomfort to major cognitive impairment. Usually, the adverse cognitive effects are ablated following dose reduction or cessation of the drug.

Medicating a child is not always easy. Many pills are made only to be swallowed, which can be difficult for a child. For some medications, chewable versions do exist.

The ketogenic diet is used to treat children who have not responded successfully to other treatments. This diet is low in carbohydrates, adequate in protein and high in fat. It has proven successful in two thirds of epilepsy cases.

In some cases, severe epilepsy is treated with the hemispherectomy, a drastic surgical procedure in which part or all of one of the hemispheres of the brain is removed.

It is unknown as to what causes abdominal epilepsy. While a causal relationship between seizure activity and the GI symptoms has not been proven, the GI symptoms cannot be explained by other pathophysiological mechanisms, and are seen to improve upon anticonvulsant treatment. Because the condition is so rare, no high-quality studies exist. There have been too few reported cases to identify risk factors, genetic factors, or other potential causes.

Because epileptic seizures may occur with a side effect that resembles migraine aura, it is complicated to diagnose whether a patient is having a normal epileptic episode or if it is a true migraine that is then being followed by a seizure, which would be a true sign of migralepsy. Many neurological symptoms can only be expressed by the patient, who can confuse different feelings, especially when the symptoms of a migraine are extremely similar to that of a seizure. Thus, many physicians are reluctant to consider migralepsy to be a true condition, considering its rarity, and those that do believe in it are prone to over-diagnose it, leading to more problems in terms of finding the truth of the condition.

However, it has been found that EEG scans have been able to differentiate between migraine auras and auras related to epilepsy. It has generally been seen that EEG scans are not as helpful in determining facets of migraines as they are with epilepsy. Though they are able to work in determining the starting and ending points of migraines and the overlap of epileptic episodes during or after them, even if the scans are still lacking in considerable necessary data and confusing results. EEG scans have been able to observe seizures that occur in between the aura and headache phase of migraines and such occurrences have been termed intercalated seizures.

The causes of epilepsy in childhood vary. In about ⅔ of cases, it is unknown.

- Unknown 67.6%

- Congenital 20%

- Trauma 4.7%

- Infection 4%

- Stroke 1.5%

- Tumor 1.5%

- Degenerative .7%

Several treatment methods have been determined exclusively for women with catamenial epilepsy. A great majority of these therapies include progestagens (naturally occurring) or progestins (synthetic progestagen). Drug interactions are an important factor when using progesterone therapy, as many antiseizure medications augment hepatic metabolism of gonadal steroids, and increase serum protein binding to hormones. There are many unfortunate side effects frequently seen in progesterone therapy usage, including vaginal dryness, dyspareunia, osteoporosis, and cardiovascular disease.

- "Cyclic progesterone therapy" supplements the patient with natural progesterone during the luteal phase when progesterone is normally low, and gradually reduces the supplementation premenstrually.

- "Suppressive progestin therapy" intends to suppress the menstrual cycle entirely by using injectable progestins or gonadotropin-releasing hormones (GnRH). GnRH basically mimics an ovary-free environment in the female, which is characteristic of the lack of menstrual cycle during menopause.

Ictal refers to a physiologic state or event such as a seizure, stroke, or headache. The word originates from the Latin "ictus", meaning a blow or a stroke. In electroencephalography (EEG), the recording during a seizure is said to be "ictal". The following definitions refer to the temporal relation with seizures.

Pre-ictal refers to the state immediately before the actual seizure, stroke, or headache, though it has recently come to light that some characteristics of this stage (such as visual auras) are actually the beginnings of the ictal state.

Post-ictal refers to the state shortly after the event.

Interictal refers to the period between seizures, or convulsions, that are characteristic of an epilepsy disorder. For most people with epilepsy, the interictal state corresponds to more than 99% of their life. The interictal period is often used by neurologists when diagnosing epilepsy since an EEG trace will often show small interictal spiking and other abnormalities known by neurologists as subclinical seizures. Interictal EEG discharges are those abnormal waveforms not associated with seizure symptoms.

Peri-ictal encompasses pre-ictal, ictal and post-ictal.

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 use of hormone replacement therapy (HRT), to lessen the effects of menopause, has shown severe negative effects on the seizure patterns of women with catamenial epilepsy. During perimenopause, women with catamenial epilepsy generally experience an increase in seizure frequency, and HRT use does not change this likelihood. However HRT use after perimenopause has been significantly associated with an increase in seizure frequency and severity. Women progressing through peri- and post-menopause using HRT may be in greater need of anticonvulsant medication monitoring to maintain or reduce seizure occurrence. These same results have not been seen in laboratory counterparts. Adult female rats that have been ovariectomized, a parallel state to menopause, show increased seizure frequency overall. There are, however, several factors that could explain this difference, including ovariectomized rats do not have the analogous brain hormones milieu as menopausal women. Several studies following HRT use in women with catamenial epilepsy have demonstrated more influencable data than animal models, in this case.

The two most common medications used in the treatment of paroxysmal sympathetic hyperactivity are morphine sulfate and beta-blockers. Morphine is useful in helping halt episodes that have started to occur. Beta-blockers are helpful in preventing the occurrence of 'sympathetic storms'. Other drugs that have been used and have in some cases been helpful are dopamine agonists, other various opiates, benzodiazepines, clonidine, and baclofen. Chlorpromazine and haloperidol, both dopamine antagonists, in some cases have worsened PSH symptoms. These drugs are in use currently for treatment; exact pathways are not known and wide-range helpfulness is speculative.

Morphine has been found to be effective in aborting episodes; sometimes it is the only medication that can combat the sympathetic response. Morphine helps lower respiration rates and hypertension. It is given in doses of two milligrams to eight milligrams but can be administered up to twenty milligrams. Nausea and vomiting are common side effects. Withdrawal is sometimes seen in patients.

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.
