A Short Note On The Automatic Seizure Detection

Seizure are uncontrolled or sudden abnormal electrical activity in the brain which causes abnormal motor and sensory activity and where the patient becomes unconsciousness. It is caused by the depolarization of the neurons. Any changes that takes place in our body that may be internal or external it can easily stimulate the irritable neurons. Seizure last for a second or a minute, in which the neurons stops unexpectedly. The pattern of electrical activity or brain waves during a seizure can be seen in EEG, by knowing what type of seizure. There are different

Epilepsy is a brain disorder in which individuals have recurrent seizures. Seizures can occur in children and adults of any age. There are around 50 million people in the world who has the disorder. Individuals in developing countries are at a higher risk for developing the disorder. Seizures occur due to hyper-excitability and hyper-synchronization of neurons. Action potential transmits messages and it leads to depolarization. When neurons are uncontrollably depolarizes because of hyper-excitability due to too little inhibition, it cause a seizure. Seizures can last from a few seconds to a few minutes. As spontaneously they can develop is also as fast and spontaneous they can end.

British seizures were humiliating to Americans because they were much stronger than France. The British added impressment to these incitements. The Royal Navy seized British civilians and forced them into service. They also seized suspicious Royal Navy deserters from American merchant ships. Impressment was upsetting to American

In the brain there is a irregular electricity that causes absence seizures. The main way to see is someone is having an absence seizure is to put them through an Electroencephalography or EEG for short. This monitors the brain waves through various wave lengths but in the case of absence seizures we are looking for a 3-Hz spike in the brain waves. This tells us if they are having an absence seizure in some other

Seizure disorders, according to the Mayo Clinic (2015), affect approximately 1 in 26 people in the United States. Persistent, or chronic, seizures result from a condition called epilepsy, a neurological disorder of the central nervous system. It can affect anyone regardless of age, but is more common during early childhood and after age 60. Given the number of people that seizure disorders, such as epilepsy, affect, it becomes helpful to gain a foundational understanding of the disease, including some of the causes, symptoms, and treatments available.

In this article I will be talking about and researching the no communicable noncommunicable dieses is Seizures. I picked this dieses because my dad has had them since he was a new born. When he was born they used forests to pull him out of the birth canal and it cause frontal brain damage and made him have Seizures for the rest of this life.

In the present time, the usage of 24-hour EEG video monitoring have proved many past physicians incorrect about their distinction between true and false seizures. EEG/video of pseudoseizures has revealed that urination, injury, and drug responsiveness may be part of nonepileptic episodes as well as epileptic episodes. As a result, EEG/video has become the gold standard for discriminating between epileptic and nonepileptic attack (Bergen, 154-155). Both clinical observation and EEG/video have reveal that long durations of start-stop pattern, direct actions, and situational triggers are more common in pseudoseizures than in true seizures (Bergen, 154-155). In addition true tonic-clonic seizures with combination of postictal oxygen debt, accumulation of saliva, and reduce level of consciousness are often followed by deep respirations and snoring or stertorous respiratory patterns, however, pseudoseizures lack these characteristics (Bergen, 154-155). The eyes remained open in every tonic-clonic and hypermotor seizures, but were closed in almost 90 percent of pseudoseizures (Bergen, 154-155). The result have shown that it is important to be able to differentiate between pseudoseizure and true seizure, but it is also crucial that physicians be able to find the underlying cause of the seizure as well.

On May 9th, 2014, I had an unexpected seizure in the middle of the night. At the time my parents were asleep, and they were awoken in a state of shock. Seizures are really scary because they are unexpected. As a matter of fact, the people who go through them are totally unaware of their surroundings and are left vulnerable to the dangers around them. Because of this drastic event, I had to go through many time-consuming tests, one of which was the EEG, which took one whole day and night at the hospital. An EEG is a very complex, expensive and time-consuming system, also it is uncomfortable for patients, especially for young children.

To diagnose your condition, your doctor will review your symptoms and medical history. After that the doctor will order several tests to diagnose epilepsy such as, neurological examination, blood test, electroencephalogram(EEG), computerized tomography(CT) scan, magnetic resonance imaging(MRI), positron emission tomography(PET), and other tests may be done.

Epilepsy Research Paper People most often associate violent twitching, falling to the floor and drooling with epilepsy. However the described event is only one kind of an epileptic seizure, which is called a tonic-clonic seizure. There are many other kinds of seizures, and each has different sets of signs and symptoms. During generalized seizures the whole brain is affected and the initial symptom is loss of consciousness. This category includes such seizures as absence seizure, myoclonic seizure, and atonic attack.

People uneducated about Epilepsy may have confused thoughts on what it really is. People have these "notions," which are partly or entirely not true. So, throughout this research paper, these notions will be proven untrue, mostly by factual information given by

A seizure is an instantaneous change in behavior provoked by electrical hyper synchronization of neuronal networks in the cerebral cortex. Most seizures can be categorized as either focal or generalized according to whether the onset of electrical activity involves a focal region of the brain or both sides of the brain simultaneously. The clinical manifestations of seizures vary based on the location of the seizure in the brain and the amount of cortex that is involved. Focal seizures are further classified by whether consciousness is altered or not during the event. Types of seizures include, focal seizures with retained awareness: This vary from one person to another, it’s dependent entirely on the part of the cortex that is disrupted at the commencement of the seizure; a seizure that begins in the occipital cortex may result in flashing lights, while a seizure that affects the motor cortex will result in rhythmic jerking movements of the face, arm, or leg on the side of the body opposite to the involved cortex also called Jacksonian seizure, a seizure that begins in the parietal cortex may cause distortion of spatial perception, and a seizure that begins in the dominant frontal lobe may cause sudden speech difficulties. The symptoms

According to World Health Organisation (2017), around 50 million people worldwide have epilepsy. Unfortunately, epilepsy cannot be cured, but could be controlled by pharmacological or electrical treatment based on seizure prediction (Moghim & Corne, 2014). Since EEG has advantages such as speed, high time resolution and non-invasive natures, it maintains one of the most frequently used tools in predicting epilepsy (Hasan et al. 2017).

The EEG is a test done where electrodes are put on the patient’s head and it will show any abnormal electrical activity due to having epilepsy. If the results come back normal the first time, the doctor may try doing the EEG while the patient is asleep to test for any abnormal activity. They may even request for a sleep-deprived test or an ambulatory EEG.

EEG signals can be used effectively to study the mental states and ailments related to the brain. The inherent issues with the EEG signal are that it is highly nonlinear in nature and its visual interpreta-tions are tedious and subjective prone to inter-observer variations. To help researchers better analyze EEG signals, we have presented various signal analysis techniques de-noising, feature extraction, classification methods in this review. Our key focus in this review was on epilepsy detection, Epi-lepsy is one of the most common neurological conditions and one of the least understood. In this regard, we have summarized the findings of many epilepsy activity classification techniques that use EEG as the base signal. The review demonstrates
