The most effective anti-epileptic medication for JME is valproic acid (Depakote). Women are often started on alternative medications due to valproic acid's high incidence of fetal malformations. Lamotrigine, levetiracetam, topiramate, and zonisamide are alternative anti-epileptic medications with less frequent incidence of pregnancy related complications, and they are often used first in females of childbearing age. Carbamazepine may aggravate primary generalized seizure disorders such as JME. Treatment is lifelong. Patients should be warned to avoid sleep deprivation.
No high quality evidence has shown any drug very useful as of 2013. Rufinamide, lamotrigine, topiramate and felbamate may be useful.
Avoidance therapy consists of minimizing or eliminating triggers. For example, in those who are sensitive to light, using a small television, avoiding video games, or wearing dark glasses may be useful. Operant-based biofeedback based on the EEG waves has some support in those who do not respond to medications. Psychological methods should not, however, be used to replace medications. Some dogs, commonly referred to as seizure dogs, may help during or after a seizure. It is not clear if dogs have the ability to predict seizures before they occur.
LGS seizures are often treatment resistant, but this does not mean that treatment is futile. Options include anticonvulsants, anesthetics, steroids such as prednisone, immunoglobulins, and various other pharmacological agents that have been reported to work in individual patients.
Valproic acid is the first line drug choice for reducing generalised seizures and myoclonus. Levetiracetam is also effective for both generalised seizures and myoclonus. Clonazepam and high-dose piracetam can alleviate myoclonus. Phenytoin can worsen seizures and may speed up neurodegeneration; carbamazepine, oxcarbazepine, tiagabine, vigabatrin, gabapentin and pregabalin may worsen myoclonus and myoclonic seizures. Other common medications to treat ULD include topiramate and zonisamide. If an individual with Unverricht–Lundborg disease is particularly sensitive to a certain type of stimulus, it is also beneficial to reduce the patient's exposure to that stimulus in order to reduce the likelihood of seizures. Since ULD is progressive and may not get better over time, depression has been documented in many cases, so providing a strong support group of friends, family, and even other individuals with ULD is very beneficial.
Alternative medicine, including acupuncture, psychological interventions, routine vitamins, and yoga, have no reliable evidence to support their use in epilepsy. There is not enough evidence to support the use of cannabis. Melatonin, as of 2016, is insufficiently supported by evidence. The trials were of poor methodological quality and it was not possible to draw any definitive conclusions.
Seizures in Dravet syndrome can be difficult to manage but may be reduced by anticonvulsant medications such as clobazam, stiripentol, topiramate and valproate. Because the course of the disorder varies from individual to individual, treatment protocols may vary. A diet high in fats and low in carbohydrates may also be beneficial, known as a ketogenic diet. Although diet adjustment can help, it does not eliminate the symptoms. Until a better form of treatment or cure is discovered, those with this disease will have myoclonic epilepsy for the rest of their lives.
Certain anticonvulsant drugs that are classed as Sodium Channel Blockers are now known to make seizures worse in most Dravet patients. These drugs include carbamazepine, gabapentin, lamotrigine, and phenytoin.
Treatments include cognitive rehabilitation through psychomotor and speech therapy. In addition, valproate is often administered to prevent recurrence of febrile seizures and benzodiazapine is used for long lasting seizures, but these treatments are usually insufficient.
Stiripentol was the only drug for which a double-blind placebo trial was performed and this drug showed efficacy in trials. It acts as a GABAergic agent and as a positive allosteric modulator of GABA receptor. Stiripentol, can improve focal refractory epilepsy, as well as Dravet's syndrome, supplemented with clobazam and valproate was approved in Europe in 2007 as a therapy for Dravet syndrome and has been found to reduce overall seizure rate by 70%. In cases with more drug resistant seizures, topiramate and the ketogenic diet are used as alternative treatments.
Cannabidiol (CBD) has received orphan drug status in the United States, for treatment of Dravet syndrome which will allow it to be studied.
While there is no current cure to repair the mutated CSTB gene, several antiepileptic drugs are effective in reducing seizures and helping patients with ULD to manage the symptoms. In addition, new research is being performed to examine the effectiveness of other types of treatments.
Based on anecdotal evidence, the drugs of choice are those used for other idiopathic generalized epilepsies. Valproate alone, or most probably in combination with clonazepam, levetiracetam, lamotrigine or ethosuximide, appears to be the most effective regimen. The choice of the second drug depends on the main seizure type. Clonazepam is highly efficacious in eyelid myoclonia and myoclonic jerks. Of the newer antiepileptic drugs, levetiracetam may be the most effective, because of its anti myoclonic and anti photosensitive properties. Lamotrigine is very effective in absence seizures but may exaggerate myoclonic jerks.
Contra-indicated drugs are: Carbamazepine, gabapentin, oxcarbazepine, phenytoin, pregabalin, tiagabine and vigabatrin.
Lifestyle and avoidance of seizure precipitants are important. Non-pharmacological treatments used for photosensitive patients (such as wearing special glasses or the newly commercially available blue Z1 lenses) should be employed in Jeavons syndrome when photosensitivity persists.
Any number of medications may be used to both prevent and treat seizures.
Generally after three medications are tried, different treatment should be considered. It should also be noted that some medications are harmful to those with this syndrome and can increase seizures.
The treatment for seizures may include antiepileptic medications, diet, and vagus nerve stimulator.
Carbamazepine, vigabatrin, and tiagabine are contraindicated in the treatment of absence seizures, irrespective of cause and severity. This is based on clinical and experimental evidence. In particular, the GABA agonists vigabatrin and tiagabine are used to induce, not to treat, absence seizures and absence status epilepticus. Similarly, oxcarbazepine, phenytoin, phenobarbital, gabapentin, and pregabalin should not be used in the treatment of absence seizures because these medications may worsen absence seizures.
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.
Treatment of patients with absence seizures only is mainly with valproic acid or ethosuximide, which are of equal efficacy controlling absences in around 75% of patients. Lamotrigine monotherapy is less effective, with nearly half of the patients becoming seizure free. This view has been recently confirmed by Glauser et al. (2010), who studied the effects of ethosuximide, valproic acid, and lamotrigine in children with newly diagnosed childhood absence epilepsy. Drug dosages were incrementally increased until the child was free of seizures, the maximal allowable dose was reached, or a criterion indicating treatment failure was met. The primary outcome was freedom from treatment failure after 16 weeks of therapy; the secondary outcome was attentional dysfunction. After 16 weeks of therapy, the freedom-from-failure rates for ethosuximide and valproic acid were similar and were higher than the rate for lamotrigine. There were no significant differences between the three drugs with regard to discontinuation because of adverse events. Attentional dysfunction was more common with valproic acid than with ethosuximide.
If monotherapy fails or unacceptable adverse reactions appear, replacement of one by another of the three antiepileptic drugs is the alternative. Adding small doses of lamotrigine to sodium valproate may be the best combination in resistant cases.
While ethosuximide is effective in treating only absence seizures, valproic acid is effective in treating multiple seizure types including tonic-clonic seizure and partial seizure, as such it may be a better choice if a patient is exhibiting multiple types of seizures.
Similarly, lamotrigine treats multiple seizure types including partial seizures and generalized seizures, therefore it is also an option for patients with multiple seizure types. Clonazepam (Klonopin, Rivotril) is effective in the short term but is not generally recommended for treatment of absence seizure because of the rapid development of tolerance and high frequency of side effects.
Lorazepam and clonazepam are front line treatment for severe convulsions, belonging to the benzodiazepine class of medications.
Anticonvulsants are the most successful medication in reducing and preventing seizures from reoccurring. The goal of these medications in being able to reduce the reoccurrence of seizures is to be able to limit the amount of rapid and extensive firing of neurons so that a focal region of neurons cannot become over-activated thereby initiating a seizure. Although anticonvulsants are able to reduce the amount of seizures that occur in the brain, no medication has been discovered to date that is able to prevent the development of epilepsy following a head injury. There are a wide range of anticonvulsants that have both different modes of action and different abilities in preventing certain types of seizures. Some of the anticonvulsants that are prescribed to patients today include: Carbamazepine (Tegretol), Phenytoin (Dilantin Kapseals), Gabapentin (Neurontin), Levetiracetam (Keppra), Lamotrigine (Lamictal), Topiramate (Topamax), Tiagabine (Gabitril), Zonisamide (Zonegran) and Pregabalin (Lyrica).
Long term management is by use of anticonvulsant medication, principally valproate, stiripentol, topiramate or clobazam. Ketogenic diet has also been found useful in certain cases
Management of breakthrough seizures is by benzodiazepine such as midazolam.
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.
The trigger needs to be identified before prescribing anti-epileptics. The most commonly prescribed drugs for reflex epilepsy are valproate, carbamazepine and clonazepam, though lamotrigine, levetiracetam are promising.
Like many mitochondrial diseases, there is no cure for MERRF, no matter the means for diagnosis of the disease. The treatment is primarily symptomatic. High doses of Coenzyme Q10, B complex vitamins and L-Carnitine are the drugs that patients are treated with in order to account for the altered metabolic processed resulting in the disease. There is very little success with these treatments as therapies in hopes of improving mitochondrial function. The treatment only alleviates symptoms and these do not prevent the disease from progressing. Patients with concomitant disease, such as diabetes, deafness or cardiac disease, are treated in combination to manage symptoms.
The most common drug used to treat AHC is flunarizine. Flunarizine functions by acting as a calcium channel blocker. Other drugs, in order of frequency of use are benzodiazepines, carbamazapine, barbiturates, and valproic acid. Flunarizine is prescribed for the purpose of reducing the severity of AHC attacks and the number of episodes, though it rarely stops attacks altogether. Minimizing the attacks may help reduce damage to the body from hemiplegic attacks and improve long-term outcomes as far as mental and physical disabilities are concerned.
Experts differ in their confidence in flunarizine's effectiveness. Some studies have found it to be very effective in reducing the duration, severity, and frequency of hemiplegic attacks. It is generally considered the best treatment available, but this drug is thought by some to be of little benefit to AHC patients. Many patients suffer adverse effects without seeing any improvement. Flunarizine also causes problems because it is difficult for patients to obtain, as it is not readily available in the United States.
There is no known definitive cure for OMS. However, several drugs have proven to be effective in its treatment.
Some of medication used to treat the symptoms are:
- ACTH has shown improvements in symptoms but can result in an incomplete recovery with residual deficits.
- Corticosteroids (such as "prednisone" or "methylprednisolone") used at high dosages (500 mg - 2 g per day intravenously for a course of 3 to 5 days) can accelerate regression of symptoms. Subsequent very gradual tapering with pills generally follows. Most patients require high doses for months to years before tapering.
- Intravenous Immunoglobulins (IVIg) are often used with varying results.
- Several other immunosuppressive drugs, such as cyclophosphamide and azathioprine, may be helpful in some cases.
- Chemotherapy for neuroblastoma may be effective, although data is contradictory and unconvincing at this point in time.
- Rituximab has been used with encouraging results.
- Other medications are used to treat symptoms without influencing the nature of the disease (symptomatic treatment):
- Trazodone can be useful against irritability and sleep problems
- Additional treatment options include plasmapheresis for severe, steroid-unresponsive relapses.
The National Organization for Rare Disorders (NORD) recommends FLAIR therapy consisting of a three-agent protocol involving front-loaded high-dose ACTH, IVIg, and rituximab that was developed by the National Pediatric Myoclonus Center, and has the best-documented outcomes. Almost all patients (80-90%) show improvement with this treatment and the relapse rate appears to be about 20%.

The following medications should probably be avoided:
- Midazolam - Can cause irritability.
- Melatonin - Is known to stimulate the immune system.

Hemiplegic attacks can be brought on by particular triggers, and management of AHC often centers around avoiding common or known triggers. While triggers vary greatly from person to person, there are also some common ones which are prevalent in many patients. Common triggers include temperature changes, water exposure, bright lights, certain foods, emotional stress, and physical activity. While avoiding triggers may help, it cannot prevent all hemiplegic episodes because many occur without being triggered. Because attacks and other associated symptoms end with sleep, various sedatives can be used to help patients sleep.
The first line treatment of choice for someone who is actively seizing is a benzodiazepine, most guidelines recommend lorazepam. This may be repeated if there is no effect after 10 minutes. If there is no effect after two doses, barbiturates or propofol may be used. Benzodiazepines given by a non-intravenous route appear to be better than those given by intravenous as the intravenous takes time to start.
Ongoing anti-epileptic medications are not typically recommended after a first seizure except in those with structural lesions in the brain. They are generally recommended after a second one has occurred. Approximately 70% of people can obtain full control with continuous use of medication. Typically one type of anticonvulsant is preferred. Following a first seizure, while immediate treatment with an anti-seizure drug lowers the probability of seizure recurrence up to five years it does not change the risk of death and there are potential side effects.
In seizures related to toxins, up to two doses of benzodiazepines should be used. If this is not effective pyridoxine is recommended. Phenytoin should generally not be used.
There is a lack of evidence for preventative anti-epileptic medications in the management of seizures related to intracranial venous thrombosis.
Concerning more serious afflictions, the complex origins of myoclonus may be treated with multiple drugs, which have a limited effect individually, but greater when combined with others that act on different brain pathways or mechanisms. Treatment is most effective when the underlying cause is known, and can be treated as such. Some drugs being studied in different combinations include clonazepam, sodium valproate, piracetam, and primidone. Hormonal therapy may improve responses to antimyoclonic drugs in some people.
Some studies have shown that doses of 5-hydroxytryptophan (5-HTP) leads to improvement in patients with some types of action myoclonus and PME. These differences in the effect of 5-HTP on patients with myoclonus have not yet been explained.
Many of the drugs used for myoclonus, such as barbiturates, phenytoin and primidone, are also used to treat epilepsy. Barbiturates slow down the central nervous system and cause tranquilizing or antiseizure effects. Phenytoin and primidone are effective antiepileptics drugs, although phenytoin can cause liver failure or have other harmful long-term effects in patients with PME. Sodium valproate is an alternative therapy for myoclonus and can be used either alone or in combination with clonazepam. Some people have adverse reactions to clonazepam and/or sodium valproate.
When patients are taking multiple medications, the discontinuation of drugs suspected of causing myoclonus and treatment of metabolic derangements may resolve some cases of myoclonus. When pharmacological treatment is indicated anticonvulsants are the main line of treatment. Paradoxical reactions to treatment are notable. Drugs which most people respond to may in other individuals worsen their symptoms. Sometimes this leads to the mistake of increasing the dose, rather than decreasing or stopping the drug. Treatment of myoclonus focuses on medications that may help reduce symptoms. Drugs used include sodium valproate, clonazepam, the anticonvulsant levetiracetam, and piracetam. Dosages of clonazepam usually are increased gradually until the patient improves or side effects become harmful. Drowsiness and loss of coordination are common side effects. The beneficial effects of clonazepam may diminish over time if the patient develops a tolerance to the drug.
In forms of myoclonus where only a single area is affected, and even in a few other various forms, Botox injections (OnabotulinumtoxinA) may be helpful. The chemical messenger responsible for triggering the involuntary muscle contractions is blocked by the Botulinum toxins of the Botox.
Surgery is also a viable option for treatment if the symptoms are caused by a tumor or lesion in the brain or spinal cord. Surgery may also correct symptoms in those where myoclonus affects parts of the face or ear. While DBS is still being studied for use with myoclonus, Deep Brain Stimulation has also been tried in those with this and other movement disorders.
