How Epilepsy Is Treated When Medications Fail Or Surgery Cannot Be Performed
<p><span style="font-weight: 400;">Epilepsy is a neurological disorder in which repeated seizures occur, which are sudden alterations in one's behaviour due to a temporary change in the electrical functioning of the brain. In normal patients, tiny electrical impulses are generated inside the brain in an orderly pattern. The electrical impulses travel inside the brain via neurons, and throughout the body via chemical messengers known as neurotransmitters. </span></p> <p><span style="font-weight: 400;">However, in an epileptic patient, the brain's electrical rhythms often become imbalanced, as a result of which recurrent seizures occur. When a seizure occurs, sudden and synchronised bursts of electrical energy disrupt the normal electrical pattern, affecting the person's consciousness, movements, or sensations, according to the American Association of Neurological Surgeons. </span></p> <p><strong>MUST READ | <a title="India Has Maximum Preterm Births Globally, Say Experts.

Know Prevalence And Survival Rate</a></strong></p> <p><span style="font-weight: 400;">When a person has had at least two seizures that did not occur to some known medical condition, they are diagnosed with epilepsy. </span></p> <p><span style="font-weight: 400;">About 50 million people worldwide are epileptic, according to the Epilepsy Foundation. </span></p> <p><strong>MUST READ | <a title="World Prematurity Day: Classification Of Preterm Babies Based On Gestational Age, And Their Body Weights And Lengths" href="https://ift.tt/ZbRtwgX" target="_self">Classification Of Preterm Babies Based On Gestational Age, And Their Body Weights And Lengths</a></strong></p> <p><span style="font-weight: 400;">Epilepsy can be treated with the help of antiepileptic medications (AEDs), diet therapy, and surgery. Most patients with multiple seizures choose medications as the initial treatment choice. </span></p> <p><span style="font-weight: 400;">There are some patients who only have a single seizure, and the tests they undergo do not indicate a high probability of seizure recurrence. Such patients do not require any medications. </span></p> <p><strong>MUST READ | <a title="Pancreatic Cancer Day: Why Robotic Surgery Is Crucial To Remove Pancreatic Tumour, And How It Is Done" href="https://ift.tt/wGve1XY" target="_self">Why Robotic Surgery Is Crucial To Remove Pancreatic Tumour, And How It Is Done</a></strong></p> <p><span style="font-weight: 400;">Medications do not cure the underlying condition of epilepsy, but only treat the symptoms. About 70 per cent of epileptic patients obtain positive results after taking medications, which work by reducing the tendency of brain cells to send excessive and confused electrical signals. </span></p> <p><span style="font-weight: 400;">Some patients receive diet therapy which involves a ketogenic diet and a modified Atkins diet. A ketogenic diet involves foods with high-fat, adequate protein, and low carbohydrates, while a modified Atkins diet is similar to the ketogenic diet, but is less restrictive. The ketogenic diet is given for three to four days in the hospital, while the modified Atkins diet can be initiated as an outpatient. </span></p> <p><span style="font-weight: 400;">“Dietary therapies like the ketogenic diet can be considered. There have been instances where this high-fat, low-carb diet has proven effective,” </span><strong><em>Dr Aditya Gupta, Director, CyberKnife, Artemis Hospital, Gurugram, told ABP Live.</em></strong></p> <p><strong>MUST READ | <a title="Can Diabetes Be Cured In The Future?

They are considered medically-resistant. </span></p> <p><span style="font-weight: 400;">For medically-resistant epileptic patients, surgery is the best option to completely control seizures. However, surgery may not be possible if the epileptic region is a part of the brain that, if removed, will result in major neurological complications. </span></p> <p><span style="font-weight: 400;">If antiepileptic medications do not control one's seizures, and brain surgery is not possible because the epileptic region is located near sensitive areas in the brain, procedures such as vagus nerve stimulation (VNS) and deep brain stimulation (DBS) may help, according to the National Health Service (NHS). </span></p> <p><strong>MUST READ | <a title="NISAR: NASA-ISRO Earth Observing Satellite To Be Launched In Early 2024, To Survey Earth Every 12 Days.

When abnormal activity occurs in the brain, bursts of electricity are sent along the wire to the nerve.</span></p> <p><span style="font-weight: 400;">According to the NHS, this can help control seizures by changing the brain's electrical signals. </span></p> <p><strong>MUST READ | <a title="Diabetes Mellitus And Diabetes Insipidus Can Occur In The Same Person At The Same Time.

Know About These Rare Cases</a></strong></p> <p><span style="font-weight: 400;">VNS is effective because the device emits controlled impulses to the vagus nerve to reduce seizures. </span></p> <p><span style="font-weight: 400;">“VNS entails placing a device in the chest, which emits controlled impulses to the vagus nerve, effectively reducing seizures,” </span><strong><em>Dr Sonia Lal Gupta, Senior Neurologist & Director, Metro Group of Hospitals, told ABP Live.</em></strong></p> <p><strong>MUST READ | <a title="How Increased Screen Time And Bad Postures Harm Neck And Spine, And What Must Be Done To Prevent Tech Neck" href="https://ift.tt/ylU4RrZ" target="_self">How Increased Screen Time And Bad Postures Harm Neck And Spine, And What Must Be Done To Prevent Tech Neck</a></strong></p> <p><span style="font-weight: 400;">While VNS does not usually completely stop seizures, it can help make them less severe and less frequent. </span></p> <p><span style="font-weight: 400;">However, VNS has some side effects such as a hoarse voice, a cough, and a spread throat when the device is activated. </span></p> <p><span style="font-weight: 400;">A VNS device's battery lasts up to 10 years, following which a new procedure will be used to replace it. </span></p> <p><strong>MUST READ | <a title="What Was Thalidomide Tragedy?

Electrodes are implanted in certain regions of the brain.</span></p> <p><span style="font-weight: 400;">“In the case of DBS, electrodes are implanted to modulate specific brain areas linked to seizures,” </span><strong><em>said Dr Lal Gupta.</em></strong></p> <p><strong>MUST READ | <a title="Stroke Is Fourth Leading Cause Of Death In India, Global Cases Projected To Increase By 50 Per Cent By 2050" href="https://ift.tt/VYGAv0n" target="_self">Stroke Is Fourth Leading Cause Of Death In India, Global Cases Projected To Increase By 50 Per Cent By 2050</a></strong></p> <p><span style="font-weight: 400;">DBS is a new technique, and is not used commonly. </span></p> <p><span style="font-weight: 400;">Some serious risk factors associated with DBS include bleeding of the brain, memory problems, and depression.</span></p> <p><span style="font-weight: 400;">“When epilepsy is close to sensitive brain regions and is not responsive to medication or surgery, other treatments such as vagus nerve stimulation (VNS) or responsive neurostimulation (RNS) may be explored. While RNS monitors brain activity and provides targeted electrical stimulation to avoid seizures, VNS entails implanting a device to stimulate the vagus nerve. When more conventional techniques are impractical because they may damage important brain regions, these strategies try to control epilepsy,”</span><strong><em> said Dr Gupta.</em></strong><span style="font-weight: 400;"> </span></p> <p><strong>MUST READ | <a title="The Science Of Health: How Climate Change And Air Pollution Impact Heart Health, And What Must Be Done" href="https://ift.tt/tATRmHv" target="_self">The Science Of Health: How Climate Change And Air Pollution Impact Heart Health, And What Must Be Done</a></strong></p> <h3><span style="color: #fa1ca5;"><strong>What is responsive neurostimulation?</strong></span></h3> <p><span style="font-weight: 400;">Responsive neurostimulation (RNS) is another technique employed to control seizures when medications do not work. As part of the RNS technique, a neurotransmitter is placed under the scalp and within the skull, and is connected to two electrodes placed either on the surface of the brain, into the brain, or a combination of both, according to the University of Pittsburgh.</span></p> <p><span style="font-weight: 400;">The neurotransmitter continuously monitors brain activity and can detect seizures. The device helps stop, shorten, or prevent seizures by delivering a small amount of electrical current to the brain when a seizure-like activity is detected in the brain.</span></p> <div class="article-data _thumbBrk uk-text-break"> <p><strong>MUST READ | <a title="Science For Everyone: Why Delhi Air Pollution Is So Severe, And What Needs To Be Done" href="https://ift.tt/kKdeUXa" target="_self">Science For Everyone: Why Delhi Air Pollution Is So Severe, And What Needs To Be Done</a></strong></p> </div> <p><span style="font-weight: 400;">Research is being conducted to develop gene therapies and advanced neurostimulation techniques that can help control seizures in patients who are unresponsive to traditional therapy, </span><strong><em>according to Dr Gupta. </em></strong></p> <p><span style="font-weight: 400;">For those dealing with difficult epileptic situations, individualised techniques that cater to their requirements can prove to be helpful.</span></p>
