Epilepsy Action Australia is an Australian charity providing education and support services to children and adults in Australia with epilepsy and other seizure disorders. The group is made up of caseworkers, registered nurses and other service providers, and aims to meet individuals' social, emotional and seizure management needs, with information, referral services and consultancy for professional organisations.
Until 2005, the group was called the Epilepsy Association of Australia.

Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. Epileptic seizures can vary from brief and nearly undetectable periods to long periods of vigorous shaking due to abnormal electrical activity in the brain. These episodes can result in physical injuries, either directly such as broken bones or through causing accidents. In epilepsy, seizures tend to recur and may have no immediate underlying cause. Isolated seizures that are provoked by a specific cause such as poisoning are not deemed to represent epilepsy. People with epilepsy may be treated differently in various areas of the world and experience varying degrees of social stigma due to their condition.
An epileptic seizure, formally known as a seizure, is a period of symptoms due to abnormally excessive or synchronous neuronal activity in the brain. Outward effects vary from uncontrolled shaking movements involving much of the body with loss of consciousness, to shaking movements involving only part of the body with variable levels of consciousness, to a subtle momentary loss of awareness. Most of the time these episodes last less than two minutes and it takes some time to return to normal. Loss of bladder control may occur.
Absence seizures are one of several kinds of generalized seizures. These seizures are sometimes referred to as petit mal seizures. Absence seizures are characterized by a brief loss and return of consciousness, generally not followed by a period of lethargy. Absence seizure is very common in children. It affects both sides of the brain.
Photosensitive epilepsy (PSE) is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights; bold, regular patterns; or regular moving patterns.
Myoclonus is a brief, involuntary, irregular twitching of a muscle or a group of muscles, different from clonus, which is rhythmic or regular. Myoclonus describes a medical sign and, generally, is not a diagnosis of a disease. These myoclonic twitches, jerks, or seizures are usually caused by sudden muscle contractions or brief lapses of contraction. The most common circumstance under which they occur is while falling asleep. Myoclonic jerks occur in healthy people and are experienced occasionally by everyone. However, when they appear with more persistence and become more widespread they can be a sign of various neurological disorders. Hiccups are a kind of myoclonic jerk specifically affecting the diaphragm. When a spasm is caused by another person it is known as a provoked spasm. Shuddering attacks in babies fall in this category.
The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used mainly to treat hard-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates.
Focal seizures are seizures which affect initially only one hemisphere of the brain. The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes. A focal seizure is generated in and affects just one part of the brain – a whole hemisphere or part of a lobe. Symptoms will vary according to where the seizure occurs. When seizures occur in the frontal lobe the patient may experience a wave-like sensation in the head. When seizures occur in the temporal lobe, a feeling of déjà vu may be experienced. When seizures are localized to the parietal lobe, a numbness or tingling may occur. With seizures occurring in the occipital lobe, visual disturbances or hallucinations have been reported.
Temporal lobe epilepsy (TLE) is a chronic disorder of the nervous system which is characterized by recurrent, unprovoked focal seizures that originate in the temporal lobe of the brain and last about one or two minutes. TLE is the most common form of epilepsy with focal seizures. A focal seizure in the temporal lobe may spread to other areas in the brain when it may become a focal to bilateral seizure.
Epilepsy in animals is a group of neurological disorders characterized by seizures, caused by abnormal bursts of electrical activity in the brain. They can start and stop very abruptly and last any amount of time from a few seconds to a few minutes. Canine epilepsy is often genetic but epilepsy in cats and other pets is rarer, likely because there is no hereditary component to epilepsy in these animals.
Myoclonic epilepsy refers to a family of epilepsies that present with myoclonus. When myoclonic jerks are occasionally associated with abnormal brain wave activity, it can be categorized as myoclonic seizure. If the abnormal brain wave activity is persistent and results from ongoing seizures, then a diagnosis of myoclonic epilepsy may be considered.
Seizure types most commonly follow the classification proposed by the International League Against Epilepsy (ILAE) in 1981. These classifications have been updated in 2017. Distinguishing between seizure types is important since different types of seizure may have different causes, outcomes and treatments.
Paramethadione is an anticonvulsant in the oxazolidinedione class developed by the Illinois-based pharmaceutical company Abbott Laboratories, and approved by the Food and Drug Administration in 1949 for the treatment of absence seizures, also called partial seizures.
The Epilepsy Society is the largest medical charity in the field of epilepsy in the United Kingdom, providing services for people with epilepsy for over 100 years. Based in Chalfont St Peter, Buckinghamshire, UK, its stated mission is "to enhance the quality of life of people affected by epilepsy by promoting research, education and public awareness and by delivering specialist medical care and support services." The Epilepsy Society has close partnerships with the National Hospital for Neurology and Neurosurgery (NHNN) and the UCL Institute of Neurology, both located in Queen Square, London.
Sultiame, also known as sulthiame, is a sulfonamide and inhibitor of the enzyme carbonic anhydrase. It is used as an anticonvulsant.
The Epilepsy Foundation, also Epilepsy Foundation of America (EFA), is a non-profit national foundation, headquartered in Bowie, Maryland, dedicated to the welfare of people with epilepsy and seizure disorders. The foundation was established in 1968 and now has a network of 59 affiliates. The foundation's programs aim to "ensure that people with seizures are able to participate in all life experiences; and to prevent, control and cure epilepsy through research, education, advocacy and services."
Generalized epilepsy is a form of epilepsy characterised by generalised seizures with no apparent cause. Generalized seizures, as opposed to focal seizures, are a type of seizure that impairs consciousness and distorts the electrical activity of the whole or a larger portion of the brain.
A generalized tonic–clonic seizure, commonly known as a grand mal seizure or GTCS, is a type of generalized seizure that produces bilateral, convulsive tonic and clonic muscle contractions. Tonic–clonic seizures are the seizure type most commonly associated with epilepsy and seizures in general and the most common seizure associated with metabolic imbalances. It is a misconception that they are the sole type of seizure, as they are the main seizure type in approximately 10% of those with epilepsy.
Epilepsy and driving is a personal and safety issue. A person with a seizure disorder that causes lapses in consciousness may be putting the public at risk from their operation of a motor vehicle. Not only can a seizure itself cause an accident, but anticonvulsants often have side effects that include drowsiness. People with epilepsy are more likely to be involved in a traffic accident than people who do not have the condition, although reports range from minimally more likely up to seven times more likely.
Epilepsy can affect employment for a variety of reasons. Many employers are reluctant to hire a person they know has epilepsy, even if the seizures are controlled by medication. If the employee suffers a seizure while at work, they could harm themselves depending on the nature of the work. Employers are often unwilling to bear any financial costs that may come from employing a person with epilepsy, i.e. insurance costs, paid sick leave etc. Many people whose seizures are successfully controlled by a medication suffer from a variety of side effects, most notably drowsiness, which may affect job performance. Many laws prohibit or restrict people with epilepsy from performing certain duties, most notably driving or operating dangerous machinery, thereby lowering the pool of jobs available to people with epilepsy. Epilepsy sufferers are also prohibited from joining the armed forces, though they may work in certain civilian military positions.
Epilepsy is the most common childhood brain disorder in the United States. Nearly 3 million people have been diagnosed with this disease, while 450,000 of them are under the age of 17. Two thirds of the child population will overcome the side effects, including seizures, through treatment during adolescence.
