Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. The occurrence of two or more unprovoked seizures defines epilepsy. The occurrence of just one seizure may warrant the definition in a more clinical usage where recurrence may be able to be prejudged. 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 detectable 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 the alarming nature of their symptoms.
Neurology is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system.
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty concerned with the surgical treatment of disorders which affect any portion of the nervous system including the brain, spinal cord and peripheral nervous system.
A psychiatrist is a physician who specializes in psychiatry. Psychiatrists are physicians and evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments or strictly mental issues. Sometimes a psychiatrist works within a multi-disciplinary team, which may comprise clinical psychologists, social workers, occupational therapists, and nursing staff. Psychiatrists have broad training in a biopsychosocial approach to the assessment and management of mental illness.
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. These episodes usually last less than two minutes and it takes some time to return to normal. Loss of bladder control may occur.
Clinical neurophysiology is a medical specialty that studies the central and peripheral nervous systems through the recording of bioelectrical activity, whether spontaneous or stimulated. It encompasses both research regarding the pathophysiology along with clinical methods used to diagnose diseases involving both central and peripheral nervous systems. Examinations in the clinical neurophysiology field are not limited to tests conducted in a laboratory. It is thought of as an extension of a neurologic consultation. Tests that are conducted are concerned with measuring the electrical functions of the brain, spinal cord, and nerves in the limbs and muscles. It can give the precise definition of site, the type and degree of the lesion, along with revealing the abnormalities that are in question. Due to these abilities, clinical neurophysiology is used to mainly help diagnose diseases rather than treat them.
The Wada test, also known as the intracarotid sodium amobarbital procedure (ISAP) or Wada-Milner Test, establishes cerebral language and memory representation of each hemisphere.
Ruben Kuzniecky is a neurologist scientist who is Vice-chair academic affairs and professor of neurology at Northwell Health specializing in the field of epilepsy, epilepsy surgery and neuro-imaging.
Psychogenic non-epileptic seizures (PNES), also referred to as non-epileptic attacks (NEA), functional seizures, or dissociative seizures, are episodes resembling an epileptic seizure but without the characteristic electrical discharges associated with epilepsy. PNES fall under the category of disorders known as functional neurological disorders (FND), also known as conversion disorders, and are typically treated by psychologists or psychiatrists. PNES has previously been called pseudoseizures, stress seizures, and hysterical seizures, but these terms have fallen out of favor.
William Gordon Lennox was an American neurologist and epileptologist who was a pioneer in the use of electroencephalography (EEG) for the diagnosis and treatment of epilepsy. He graduated from Colorado College and Harvard Medical School.
Frederick Andermann was a Canadian neurologist and epileptologist.
The American Academy of Neurology (AAN) is a professional society representing over 40,000 neurologists and neuroscientists. As a medical specialty society it was established in 1948 by A.B. Baker of the University of Minnesota to advance the art and science of neurology, and thereby promote the best possible care for patients with neurological disorders. It is headquartered in Minneapolis and maintains a health policy office in Washington, D.C.
Post-traumatic seizures (PTS) are seizures that result from traumatic brain injury (TBI), brain damage caused by physical trauma. PTS may be a risk factor for post-traumatic epilepsy (PTE), but a person having a seizure or seizures due to traumatic brain injury does not necessarily have PTE, which is a form of epilepsy, a chronic condition in which seizures occur repeatedly. However, "PTS" and "PTE" may be used interchangeably in medical literature.
Epilepsy and driving is a personal and public safety issue. A person with a seizure disorder that causes lapses in consciousness may put themselves and the public at risk if a seizure occurs while they are operating a motor vehicle. Not only can a seizure itself cause a car wreck, but anticonvulsants often have side effects that include drowsiness. People with epilepsy are more likely to be involved in a traffic collision than people who do not have the condition, although reports range from minimally more likely up to seven times more likely.
Generally, seizures are observed in patients who do not have epilepsy. There are many causes of seizures. Organ failure, medication and medication withdrawal, cancer, imbalance of electrolytes, hypertensive encephalopathy, may be some of its potential causes. The factors that lead to a seizure are often complex and it may not be possible to determine what causes a particular seizure, what causes it to happen at a particular time, or how often seizures occur.
Epilepsy-intellectual disability in females also known as PCDH19 gene-related epilepsy or epileptic encephalopathy, early infantile, 9 (EIEE9), is a rare type of epilepsy that affects predominately females and is characterized by clusters of brief seizures, which start in infancy or early childhood, and is occasionally accompanied by varying degrees of cognitive impairment. The striking pattern of onset seizures at a young age, genetic testing and laboratory results, potential developmental delays or developmental regression and associated disorders, eases diagnosis.
The Mischer Neuroscience Institute is a combined research and education effort between the Vivian L. Smith Department of Neurosurgery and the Department of Neurology at McGovern Medical School at UTHealth Houston and Memorial Hermann Hospital. Located in Houston, the Institute draws patients from around the world for specialized treatment of diseases of the brain and spine. It was the first center in Texas and one of only a few institutions in the country to fully integrate neurology, neurosurgery, neuroradiology, neuro-oncology, spine surgery, pain medicine and neurorehabilitation.
John Mark Freeman was an American pediatric neurologist specializing in epilepsy. He is known for bringing two long-abandoned treatments for pediatric epilepsy back into popular use. One, the ketogenic diet, is a carefully managed, low-carbohydrate high-fat diet plan that reduces the incidence of seizures in children during and after its use, and the other, the hemispherectomy, is a drastic surgical procedure in which part or all of one highly seizure-prone hemisphere of the brain is removed to alleviate severe epilepsy.
A neonatal seizure is a seizure in a baby younger than age 4-weeks that is identifiable by an electrical recording of the brain. It is an occurrence of abnormal, paroxysmal, and persistent ictal rhythm with an amplitude of 2 microvolts in the electroencephalogram,. These may be manifested in form of stiffening or jerking of limbs or trunk. Sometimes random eye movements, cycling movements of legs, tonic eyeball movements, and lip-smacking movements may be observed. Alteration in heart rate, blood pressure, respiration, salivation, pupillary dilation, and other associated paroxysmal changes in the autonomic nervous system of infants may be caused due to these seizures. Often these changes are observed along with the observance of other clinical symptoms. A neonatal seizure may or may not be epileptic. Some of them may be provoked. Most neonatal seizures are due to secondary causes. With hypoxic ischemic encephalopathy being the most common cause in full term infants and intraventricular hemorrhage as the most common cause in preterm infants.
Musicogenic epilepsy is a form of reflex epilepsy with seizures elicited by special stimuli.
