Musicogenic Epilepsy
Musicogenic epilepsy is a form of reflex epilepsy with seizures elicited by special stimuli. It has probably been described for the first time in 1605 by the French philosopher and scholar Joseph Justus Scaliger (1540-1609). Later publications were, in the eighteenth century, among others, by the German physician Samuel Schaarschmidt, in the nineteenth century 1823 by the British physician John C. Cooke, 1881 by the British neurologist and epileptologist William Richard Gowers, as well as in 1913 by the Russian neurologist, clinical neurophysiologist and psychiatrist Vladimir Mikhailovich Bekhterev. In 1937 the British neurologist Macdonald Critchley coined the term for the first time and classified it as a form of reflex epilepsy. Most patients have temporal lobe epilepsy. Listening, probably also thinking or playing, of usually very specific music with an emotional content triggers focal seizures with or without loss of awareness, occasionally also evolving to bilateral tonic ...

Reflex Epilepsy
Reflex seizures are epileptic seizures that are consistently induced by a specific stimulus or trigger, making them distinct from other epileptic seizures, which are usually unprovoked. Reflex seizures are otherwise similar to unprovoked seizures and may be focal (simple or complex), generalized, myoclonic, or absence seizures. Epilepsy syndromes characterized by repeated reflex seizures are known as reflex epilepsies. Photosensitive seizures are often myoclonic, absence, or focal seizures in the occipital lobe, while musicogenic seizures are associated with focal seizures in the temporal lobe. Triggers may include various stimuli with the most common (75 to 80%) being flickering lights resulting in photosensitive seizures. Reflex epilepsies are generally thought to be genetic in origin. The inheritance pattern is dependent on the type of reflex epilepsy, with some types lacking specific genetic inheritance patterns. For example, photogenic epilepsy is thought to follow an au ...

Single-photon Emission Computed Tomography
Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomography, tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D computer graphics, 3D information. This information is typically presented as cross-sectional slices through the patient, but can be freely reformatted or manipulated as required. The technique needs delivery of a gamma-emitting radioisotope (a radionuclide) into the patient, normally through injection into the bloodstream. On occasion, the radioisotope is a simple soluble dissolved ion, such as an Isotopes of gallium, isotope of gallium(III). Usually, however, a marker radioisotope is attached to a specific ligand to create a radioligand, whose properties bind it to certain types of tissues. This marriage allows the combination of ligand and radiopharmaceutical to be carried and bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epilepsy Types
Epilepsy is a group of non-communicable neurological disorders characterized by a tendency for recurrent, unprovoked seizures. A seizure is a sudden burst of abnormal electrical activity in the brain that can cause a variety of symptoms, ranging from brief lapses of awareness or muscle jerks to prolonged convulsions. These episodes can result in physical injuries, either directly, such as broken bones, or through causing accidents. The diagnosis of epilepsy typically requires at least two unprovoked seizures occurring more than 24 hours apart. In some cases, however, it may be diagnosed after a single unprovoked seizure if clinical evidence suggests a high risk of recurrence. Isolated seizures that occur without recurrence risk or are provoked by identifiable causes are not considered indicative of epilepsy. The underlying cause is often unknown, but epilepsy can result from brain injury, stroke, infections, tumors, genetic conditions, or developmental abnormalities. Epilepsy ...

Musicogenic Seizure
Musicogenic seizure, also known as music-induced seizure, is a rare type of seizure, with an estimated prevalence of 1 in 10,000,000 individuals, that arises from disorganized or abnormal brain electrical activity when a person hears or is exposed to a specific type of sound or musical stimuli. There are challenges when diagnosing a music-induced seizure due to the broad scope of triggers, and time delay between a stimulus and seizure. In addition, the causes of musicogenic seizures are not well-established as solely limited cases and research have been discovered and conducted respectively. Nevertheless, the current understanding of the mechanism behind musicogenic seizure is that music triggers the part of the brain that is responsible for evoking an emotion associated with that music. Dysfunction in this system leads to an abnormal release of dopamine, eventually inducing seizure. Currently, there are diverse intervention strategies that patients can choose from depending on thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music-specific Disorders
Neuroscientists have learned much about the role of the brain in numerous cognitive mechanisms by understanding corresponding disorders. Similarly, neuroscientists have come to learn much about music cognition by studying music-specific disorders. Even though music is most often viewed from a "historical perspective rather than a biological one"Zatorre, R., & McGill, J. (2005). Music, the food of neuroscience rticle Nature, 434(7031), 312-315 music has significantly gained the attention of neuroscientists all around the world. For many centuries music has been strongly associated with art and culture. The reason for this increased interest in music is because it "provides a tool to study numerous aspects of neuroscience, from motor skill learning to emotion". Overview An important technique that is used by neuroscientists in understanding the cognition of music involves understanding musical disorders. This article describes some of the disorders that have been identified by n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epilepsy Surgery
Epilepsy surgery involves a neurosurgery, neurosurgical procedure where an area of the brain involved in seizures is either resected, ablative brain surgery, ablated, disconnected or stimulated. The goal is to eliminate seizures or significantly reduce seizure burden. Approximately 60% of all people with epilepsy (0.4% of the population of industrialized countries) have focal epilepsy syndromes. In 20% to 30% of these patients, the condition is not adequately controlled with adequate trials of two Anticonvulsant, anticonvulsive drugs, termed drug resistant epilepsy, or refractory epilepsy. Such patients are potential candidates for surgical epilepsy treatment. First line therapy for epilepsy involves treatment with anticonvulsive drugs, also called antiepileptic drugs– most patients will respond to trials of one or two different medications. The goal of treatment is the elimination of seizures, since uncontrolled seizures carry significant risks, including injury and sudden une ...

Awareness
In philosophy and psychology, awareness is the perception or knowledge of something. The concept is often synonymous with consciousness. However, one can be aware of something without being explicitly conscious of it, such as in the case of blindsight. The states of awareness are also associated with the states of experience so that the structure represented in awareness is mirrored in the structure of experience. Concept Awareness is a relative concept. It may refer to an internal state, such as a visceral feeling, or on external events by way of sensory perception. It is analogous to sensing something, a process distinguished from observing and perceiving (which involves a basic process of acquainting with the items we perceive). Awareness can be described as something that occurs when the brain is activated in certain ways, such as when the color red is seen once the retina is stimulated by light waves. This conceptualization is posited due to the difficulty in developin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seizures
A seizure is a sudden, brief disruption of brain activity caused by abnormal, excessive, or synchronous neuronal firing. Depending on the regions of the brain involved, seizures can lead to changes in movement, sensation, behavior, awareness, or consciousness. Symptoms vary widely. Some seizures involve subtle changes, such as brief lapses in attention or awareness (as seen in absence seizures), while others cause generalized convulsions with loss of consciousness ( tonic–clonic seizures). Most seizures last less than two minutes and are followed by a postictal period of confusion, fatigue, or other symptoms. A seizure lasting longer than five minutes is a medical emergency known as status epilepticus. Seizures are classified as provoked, when triggered by a known cause such as fever, head trauma, or metabolic imbalance, or unprovoked, when no immediate trigger is identified. Recurrent unprovoked seizures define the neurological condition epilepsy. Clinical features Seizur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Seizures
Focal seizures are seizures that originate within brain networks limited to one hemisphere of the brain. In most cases, each seizure type has a consistent site of onset and characteristic patterns of spread, although some individuals experience more than one type of focal seizure arising from distinct networks. Seizure activity may remain localized or propagate to the opposite hemisphere. 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. , E ...

Temporal Lobe Epilepsy
In the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. Seizure symptoms and behavior distinguish seizures arising from the mesial (medial) temporal lobe from seizures arising from the lateral (neocortical) temporal lobe. Memory and psychiatric comorbidities may occur. Diagnosis relies on electroencephalographic (EEG) and neuroimaging studies. Anticonvulsant medications, epilepsy surgery, and dietary treatments may improve seizure control. Types Under the International League Against Epilepsy (ILAE) 2017 classification of the epilepsies, focal onset epilepsy occurs from seizures arising from a biological neural network within a single cerebral hemisphere. Temporal lobe epilepsy occurs from seizures arising within the temporal lobe. Temporal lobe epilepsy is the most common focal onset epilepsy, and 80% of ...
