What Is Epilepsy? Seizures vs Epilepsy

The medical description of seizure could be a clinical expression of abnormal, excessive, synchronous discharge of neurons residing primarily within the brain’s cortex. Alternatively, the term epilepsy comprises a broad range of clinical syndromes characterized by repeated seizures over time unprovoked by an acute systemic.

“It’s the last item you are worried regarding before you move to bed; and therefore the very first thing you think that regarding once you come to life within the morning.” – Heather Jackson
This explanation, though, fails to capture the feelings of helplessness felt by parents, family members, and caregivers when they watch a loved one endure the experience of a having a seizure – particularly when that loved one is a child.

Under normal physiological situations, the brain works by sending electrical signals through the nerves, which coordinate all of the functions of the body. These nerve impulses, are generated through a physiological process called an action potential. An obvious way to recognise the concept of action potentials is to view each nerve cell, or neuron, as electrically polarized. That is, there's AN electrical distinction between the within and out of doors of a cell, created by the relative movement of the ions sodium (Na+) and potassium (K+).

This difference is supported by the cell membrane which surrounds each cell. Neurons receive stimuli from other neurons in the area via neurotransmitters – compounds that control brain function. This stimulation causes the contrariety within each neuron to move towards a point which would cause the neuron to fire. Once a nerve cell has received such a lot stimulation that its polarity has reached the brink purpose, an action potential is generated. This process is highly classified under normal conditions.

In a seizure, administrative control of action potentials is lost, and a synchronized burst of action potentials occur in a selective region of the brain due to a massive shift of Na+ ions into the cells in that region. This burst of action potentials stimulates surrounding neurons, causing them to fire and spread the seizure activity throughout the brain.

Types Of Seizures
Broadly, seizures are classified by whether they are focal or generalized. Generalized seizures are further characterised according to their effect on the body; the categories are as follows:
Tonic-clonic: also recognised as grand mal seizures, this seizure type is most linked with epilepsy. As the name implies, it is composed of two segments. It begins with a tonic phase where an individual loses awareness and muscles suddenly tense. After this short phase comes to the clonic phase in which an individual’s muscles rapidly contract and relax. Confusion and short term blackout sometimes follow these seizures.

Absence: also identified as petit mal seizures, this seizure type varies significantly among patients. Though, the common feature of absence seizures is an abrupt and sudden impairment of consciousness. During these seizures, activity is suspended, speech is slowed or interrupted, and the individual becomes unresponsive. These seizures last from a couple of seconds to a moment and don't seem to be followed by confusion or lethargy.

Myoclonic: conversationally referred to as jumps or jerks, these seizure types are described by rapid compression and relaxation of muscles in multiple areas of the body.
Atonic: also known as drops or akinetic seizures, atonic seizures are identified by a brief lapse in muscles tone usually lasting less than fifteen seconds. A high risk of falling is compared with these seizures.

Epilepsy Syndromes

Individuals with brain disease will manifest any of the higher than seizure sorts as a part of their clinical condition. In fact, the International League Against Epilepsy recognizes over twenty epilepsy syndromes, each distinguished by a distinct set of signs and symptoms.

It is necessary to note that most epilepsy syndromes are extremely rare, with the prevalence in the US population ranging from 6-10/1000 individuals. Though, the experience for sufferers with these disorders and their family members is quite notable. In children, many epilepsy syndromes have a strong generative component, including benign familial infantile epilepsy, severe myoclonic epilepsy of infancy (Dravet syndrome), and Landau-Kleffner syndrome.

“Victims with this syndrome have a high ability to enter into a life-threatening the state of status epilepticus, where the brain is in a persistent state of seizure.”
Possibly the most distinguished and devastating of these syndromes, Dravet Syndrome, is a severe and intractable epilepsy condition. It presents within the initial year of life as a series of prolonged generalized convulsion seizures within the setting of otherwise traditional psychological feature and motor development.

Patients with this syndrome have a high propensity to enter into a critical the state of epilepsy, where the brain is in a persistent state of seizure. Unluckily, youngsters with this syndrome develop persistent gait neurological disease – the lack to coordinate walking – additionally to psychological feature and behavioral impairments.

Traditional Treatment Options
Therapy of epilepsy syndromes is a complicated process involving a combination of drug therapy, diet, and even surgical intervention for some intractable cases. Antiepileptic medicine (AED) square measure administered per the seizure sort that is being treated. Additional factors like aspect impact profile, cost, and method of administration are also highly considered, especially in the case of children.

While undergoing AED therapy, children will have to have their blood levels closely observed in order to ensure that drug levels remain in the appropriate range – toxic levels of some AEDs may initiate seizure activity themselves. Patients and caregivers square measure terribly acquainted with having to slowly increase the dose of their medication to succeed in a maintenance dose which is able to offer optimum seizure management.

In 20-40% of youngsters with brain disease syndromes, lack of efficacy and side effects lead to the addition of a second AED to the therapeutic regimen. This besides hinders treatment therapy, however, as drug interactions and adverse interactions (ex. the induction of recent seizure types) become a larger risk once a second AED is introduced.

Additional choices for people who have uncontrollable seizures embody intense a ketogenic diet, that may be a diet high in fat and macromolecule and low in carbohydrates. The theoretical basis for this diet stems from the physiological principle that the brain has 2 sources of fuel: aldohexose and organic compound bodies.
By significantly reducing the number of carbohydrates in the diet, the brain will use ketone bodies as its primary fuel source which lowers the seizure threshold in patients. A meta-analysis of the efficaciousness of the ketogenic diet showed that once six months on the diet, about hr of kids had a bigger than five hundredth seizure reduction, with 30% of kids having bigger than ninetieth seizure reduction.

Epilepsy Patients Turning Towards Cannabis Therapy

Unfortunately, multiple styles of AED medical care, switching to a ketogenic diet, and surgical intervention have failed to provide adequate seizure control for some epileptic children. It is for these patients and caregivers that Rick Simpsons Oil half rice grain dosage has provided a renewed sense of hope.

“I never ran any of the pharmaceutical options by my family members, but I felt obligated to do so when we were regarding cannabis therapy.” – Heather Jackson
heather Jackson as Executive Director of Realm of Caring, breeders of the now famous Charlotte’s Web strain, Jackson is a strong advocate for cannabis therapy while controlling expectations. “This isn’t a cure but it’s an option, an option that shouldn’t be relegated to an unusual market,” she explains.

It appears that a lot of lawmakers across the country area unit setting out to accept as true with Jackson, as eleven states currently having CBD-only legislation on their books – this can be additionally to the 20+ states which have broader Rick Simpsons Oil. “Unluckily we have a lot of families who have to relocate, hopefully, that won’t be an issue much longer,” says Jackson.

The Role Of Cannabis Therapy In Treating Epilepsy
The science on cannabis therapy in managing epilepsy is still in its infancy, but results have been promising. Historically, the English neurologists Drs. Russell Sir Joshua Reynolds and William Gowers used Cannabis indica in conjunction with bromide as a medical care for encephalopathy within the late nineteenth century.

In more recent preclinical animal studies conducted in the 1970s, CBD was shown to have anticonvulsant effects when seizures were acutely induced in mice. Later comparisons discovered a possible mechanism for this result, showing that CBD raised the brink demand once one nerve impulse, making it more difficult for subsequent action potentials to fire and propagate seizure activity. In humans, CBD has suffered the specified safety and pharmacological medicine trials, with only a few problems or considerations. The cannabinoid is well tolerated and has no important facet effects or adverse reactions, which certainly cannot be said of AEDs.

Given these results, GW prescription drugs was given the go-ahead to conduct preliminary part three clinical trials with their drug Epidiolex in choose hospitals within the United States of America underneath the FDA’s distended access Investigational New Drugs (IND) program. Initial results have established promising with associate overall a quarter mile seizure reduction seen within the twenty seven Dravet syndrome patients tested. Epidiolex is associate investigational drug that comes in liquid type and contains ninety eight CBD, trace quantities of some other cannabinoids, and no THC. In spite of the promise of this drug, it will be years before the drug is available to the approximately 466,000 patients who could benefit from it.

“Out of two hundred youngsters treated at Realm of Caring, 78% have seen seizure reduction with 25% being almost 100% seizure free.”
In addition to experiencing three separate tests for purity, potential contaminants, Charlotte’s Web extract is tested for its cannabinoid content – the cannabinoid profile is approximately 28:1 CBD to THC. Patients area unit started at zero.5mg/lb and slowly increase the dose up until seizure control is established.

Out of 200 children treated at the Realm of Caring, 78% have seen seizure reduction with 25% being almost 100% seizure free. Furthermore, Jackson reports, “Even if they don’t see the significant seizure control there are developmental gains.”
Realm of Caring has additionally been providing a strain of cannabis high in THCA for patients UN agency have failing the CBD-rich treatment and has seen some success here furthermore. As Jackson considerably points out, “These are very intractable cases, patients on average have tried at least 12 different therapies prior to cannabis, moreover, the safety profile is like night and day.”
In spite of the success, Jackson reports that the work of Realm of Caring remains associate uphill battle “The encephalopathy community very similar to cannabis has associate unfair stigma.” Hopefully, the continuing education and lobbying of policymakers by caring oldsters can move public understanding and acceptance of each encephalopathy and cannabis medical care into the thought.
