3 Common Seizure Triggers

3 Common Seizure Triggers

Pamela Bandelaria |Apr 5, 2022

What Triggers Seizures?

This article will explore the common triggers of seizures, as well as a treatment option like FINTEPLA, a prescription medicine used to treat seizures associated with Dravet syndrome and Lennox-Gastaut syndrome. Dravet syndrome (DS) is a severe form of epilepsy characterized by frequent, prolonged seizures often triggered by high body temperature.

What is a Seizure?

The brain, comprising of nerve cells, communicates and functions by transmitting electrical activity from one nerve cell to another. This is how we are able to think, move and feel. When there is a disruption in electrical activity, this can affect our thoughts, feelings and movements. A seizure is an uncontrolled surge of electrical activity by the brain, which leads to changes in consciousness and involuntary movement of our muscles.

Seizures not only disrupt electrical activity but also disrupt oxygen transport and delivery. This is why, even though seizures usually resolve on their own, the aim is to prevent them from happening. Repeated seizures and seizures that occur for a prolonged period of time can lead to irreversible complications. The brain is one of the organs that continuously needs oxygen, and permanent brain damage can be observed in just minutes without an adequate oxygen supply. In severe cases, this can be life-threatening.

Seizure Symptoms

Seizures may present in various ways. The classic presentation of a person experiencing a seizure includes:

  • Eyes that are rolled upward.
  • Arms and legs exhibiting stiffening or jerking movements. This is due to the disruption in brain activity, which affects the muscles of the body.
  • Sitting still and staring.
  • Small, twitching movements in the fingers or face.
  • A sudden stop in breathing or changes in breathing patterns.
  • Loss of bowel and bladder control can lead someone to soiling themselves.

What Triggers a Seizure?

Once a seizure begins, there is little that can be done except wait for the seizure to cease or take the person to the nearest health facility. However, some seizures are more likely to occur under certain circumstances, wherein a pattern can be noted. In some cases, these situations can trigger a seizure, with increased chances of it happening. For people who have recurrent seizures, identifying these seizure triggers is helpful in seeing if a seizure might possibly happen and when these factors are removed, can the seizure be prevented. The following section discusses some common seizure triggers.

1. Stress

Although there are still debates as to whether or not stress can really trigger seizures, it is one of the most common factors perceived by people who experience recurrent seizures. Studies show that during periods of stress, there is an increase in the frequency of seizures experienced by patients with epilepsy. It is hypothesized that it can be due to the release of cortisol, which has excitatory properties that can further contribute to the occurrence of seizures.

2. Sleep Problems

Sleep problems have also been considered as another seizure trigger. Lack of sleep and disrupted sleep were found to contribute to the occurrence of seizures, even in the absence of other triggers or factors. Poor quality of sleep has also been perceived by patients to trigger some seizures, although data is not as strong compared to the quantity of sleep. Sleep deprivation as a seizure trigger is due to its effect on gamma-aminobutyric acid (GABA) receptors. Some studies show that treatment of sleep problems also results in fewer occurrences of seizures.

3. Flashing Lights and Bright Lights

Exposure to bright lights or flashes of light can also cause seizures. This occurs in around
3% of people with epilepsy. This kind of epilepsy is called photosensitive epilepsy.

Examples of light sources that can trigger seizures include:

  • Light from television screens or computer monitors.
  • Strobe lights.
  • Flashing lights in vehicles.
  • Natural light or sunlight.

Avoiding these can be helpful in reducing the occurrence of seizures in susceptible patients.

When seeing a seizure, it can look scary at first. Most people panic when they see someone experiencing a seizure episode. However, knowing how to deal with this medical situation and knowing how to identify seizure triggers can be extremely helpful and lifesaving.

In Conclusion

Seizures are one of the most well-documented symptoms everyone is familiar with. It is one of the symptoms commonly shown in movies and shows and the most common acute neurologic problem in the U.S. Data shows that around 1 in 10 people will have a seizure not caused by an injury, such as a concussion, illness, or infection. This might make you ask, “What triggers seizures?” First, you need to understand that recurrent seizures, also known as epilepsy, are the third most common serious neurologic disorder and occur in 1 in 26 people. Around 3.4 million Americans live with this condition.

Although many people know what a seizure is, not everyone knows what to do when it happens, and even fewer know that some seizures can be anticipated or preempted. Knowing when a seizure will occur is important to prepare appropriately, and in some cases, even prevent seizures from happening. This article will discuss what a seizure is, what the symptoms of a seizure are and what triggers seizures.

3 Lung Cancer Treatments

Staff Writer | April 5, 2022

Pathways to Healing Lung cancer starts in the lungs but can spread to other regions of the body. While there is no single cure, there are different treatment options that can be used. In this article, we will look at treatment options, as well as symptoms of lung cancer Roughly 1 in 16 Americans will be diagnosed with lung cancer. While smoking can increase the likelihood of getting a diagnosis, non-smokers are not exempt from this condition. There are many different causes of lung cancer, and people of all ages can be diagnosed. Unfortunately, there is no specific cure for lung cancer. Beating cancer is a little more complicated than taking a few pills or going to a doctor’s office. The disease is more serious and requires more intense intervention techniques. Different Lung Cancer Treatment Options Depending on the progression of the cancer and the patient's general health, a physician may recommend several treatment options. Know that with all treatment options, there is a risk of harsh side effects and a chance that the treatment does not work. Still, these are the best options when it comes to defeating lung cancer, with increased chances of success in cases of early detection. Treatments can be used in combination with one another, or as a standalone option depending on the particular case. Chemotherapy Chemotherapy has been one of the most common treatment options for a long time. It works by using strong chemicals that target rapidly dividing cells. When introduced into your body, chemotherapy drugs will attack all rapidly dividing cells. Unfortunately, these drugs cannot differentiate between cancer cells and healthy cells that just happen to be dividing. The side effects of such treatments can be unpleasant, but most reverse when the treatment ends or can be reduced during the treatment. Common side effects include: Nausea/vomiting. Hair loss. Mouth sores. Pain. Bowel disturbances (diarrhea/ constipation). Loss of appetite. Bruising easily. [youmaylike] Harsher and potentially permanent side effects include: Organ damage (heart, lung, kidneys). Nerve damage. Infertility. Heightened risk of a second cancer. Side effects will also vary depending on the type of drug that is used in your treatment and the way you “take in” the drug. The most common chemotherapy drugs for lung cancer include the following: Afatinib. Bevacizumab. Ceritinib. Crizotinib. Erlotinib. Chemotherapy for lung cancer can be done in the following ways: Injected: Most often this is administered through infusions (IV) but can be given through shots. Implanted: Thin wafers containing the drug can be inserted directly into the site of a tumor or surgery. Pills: Pills and capsules containing the drug are sometimes available. Radiation Radiation is another treatment method. Radiation therapy uses beams of energy to damage cells in targeted regions of the body. The intense energy beams aim at precise locations in the body and damage the cells in that region. While this, unfortunately, means that healthy cells will also be attacked, they are often able to “bounce back” from the damage where cancer cells will be killed. As it is a targeted treatment, side effects are often limited to the region in which the treatment was applied. This means that patients can expect skin problems in the area of application as well as fatigue; these are mostly short-term side effects. Specific side effects characterized by treatments aimed at the chest include: Breast soreness. Stiff shoulders. Difficulties swallowing. Respiratory problems. Radiation fibrosis (permanent lung scarring). There is a low chance of developing long-term side effects, such as the development of a second cancer, as an effect of radiation exposure. Surgery If the cancer is caught early enough, then it can be treated by removing the cancerous tissue at the initial site. The operation can only be successful if the cancer has not yet spread to other regions of the body. The side effects of this treatment will depend on the depth of the removal, the nature of the removed tissue, and its size. For example, removing a tiny bit of the lung will not be as hard to recover from as removing a large piece. Other Lung Cancer Treatment Options Other treatments are being developed that aim to keep the effectiveness of chemotherapy and radiation treatments without the harsh side effects. While some remain experimental, recently emerging treatments, such as immunotherapy, offer the potential to battle lung cancer. Talk to a licensed care physician to get the most valuable recommendations on which cancer treatment is right for you. Everybody has a different experience and treatments are decided on a case-by-case basis.

What Are the Early Symptoms of Colon Cancer?

Staff Writer | April 5, 2022

Early Detection Saves Lives Before you can fully understand early symptoms of colon cancer, it is important to understand where exactly it occurs within your body. A colon refers to the final part of the digestive system; specifically, it is part of the large intestine. The purpose of a colon is to help prepare your digested foods for excretion. It stores your waste as it waits to vacate your body and plays a very minor part in extracting nutrients in the final stages of digestion. What is Colon Cancer? As the name suggests, colon cancer is a cancer that starts in the colon. Cancer occurs when cells, instead of replicating at a regular rate, begin to divide rapidly, causing tumors to form, and disrupting healthy bodily functions. As cancers progress, the growing cells can travel to other regions of the body. [youmaylike] What are Polyps? Polyps are growths that can grow within the colon. Having polyp growth does not mean you will get colon cancer. While not all polyps are cancerous, almost all malignant tumors in the colon start as polyps. Upon examination, your doctor will be able to give you more information on what your options are. Generally, a physician will perform a colonoscopy to remove it. Once removed, a pathologist can examine the tissue to determine whether or not the sample is dangerous and if further actions need to be taken. Symptoms of Polyps Polyps are not something you can see. To know something is not quite right, you will have to monitor your regular bodily functions. The most commonly reported symptoms related to polyp formation are: Rectal bleeding: If you notice that your rectum is bleeding, this could be due to polyp formation. It is important to recognize that this is also a common symptom of other problems such as hemorrhoids or anal tears. If it happens persistently, you should consider visiting your doctor for an internal examination. Abdominal pain: When polyps are rather big, they can obstruct the bowel. In doing so, it can cause problems that manifest as cramps or other abdominal pain. Irregular-colored stools: Even if you cannot notice it directly, rectal bleeding can influence the color of the stool. You may notice some small red stripes in mild cases. In more serious cases, heavy bleeding may cause your poop to appear black. Before you start to worry, make sure these color changes are not simply due to a change in diet, medication, or supplement use. Anemia: If polyps continue to bleed for a prolonged time, they may cause the development of an iron deficiency. Anemia can manifest in several ways, including fatigue, shortness of breath, feeling dizzy, fainting, or having abnormally pale skin. Common Early Symptoms of Colon Cancer Polyps themselves are, again, not a direct indication of colon cancer. While cancer can develop from a polyp, there are other symptoms which separate the benign and malignant development. Symptoms of colon cancer are different for everyone, but the most commonly reported signs are: Changes in bowel movements: Particularly, you want to pay attention to the consistency of your stools. If it looks different or you develop constipation or diarrhea for an extended time, talk to your doctor. Rectal bleeding: You might pass bloody stools. Abdominal pain: Any type of discomfort, such as cramps or gas, should be monitored. Fatigue: Feeling weak or consistently tired despite adequate rest can be a sign of many medical problems. Weight loss: Unexplained weight loss may be a sign of a lack of nutrition due to a malfunctioning digestive tract. Essentially, if your intestines are not able to properly absorb nutrients from food, you will not get enough nutrition from the food you eat. The “feeling” of a full bowel: Sometimes, even after passing a bowel movement to the highest extent possible, some patients report feeling like their bowel is not “empty”. While this is a normal sensation to experience from time to time, it can be a sign of an underlying colon problem. When to See a Doctor If you notice any of these symptoms mentioned above consistently, you should schedule an appointment with a licensed physician. Even if your abnormalities are not cancerous, they can be a sign of another serious medical condition that should be addressed. The earlier you recognize a problem, the better chance you have of getting access to effective medical intervention.

Understanding the Signs and Symptoms of Lung Cancer

Staff Writer | April 5, 2022

Awareness Saves Lives Lung cancer occurs when cancerous cells form in the lungs. Like other cancers, as the disease develops, tumors are formed. As the disease progresses, it has the potential to spread to other regions of the body. Lung cancer is an umbrella term referring to several different cancers in the lung, including non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLCs start in lung tissue. It is comprised of three specific diseases: adenocarcinomas, squamous cell carcinomas, and large cell carcinomas. SCLCs are a rarer form, originating in the bronchi. They are similar in symptoms, diagnosis, treatment, and risk factors. SCLCs tend to be more aggressive than NSCLCs. When cancer is more “aggressive”, it means that the growth of the cancer cells is more rapid. Rapid progression of cancer means that tumors grow faster and spread to other parts of the body more quickly, meaning the time window for “effective” treatment is smaller and the prognosis is poorer than non-aggressive cancers. Getting a Diagnosis Anyone can get lung cancer. This is no population of people that have absolute immunity from the disease. That being said, certain groups of people are more likely to contract lung cancer than others. [youmaylike] Generally, lung cancer is found in older people over the age of 65. Some lifestyle choices, such as smoking tobacco, can increase the risk of getting a diagnosis. Remember, just are there are no populations that are immune to developing cancer, but there are plenty of “at-risk” individuals who will never develop it. This does not mean you should ignore warnings over certain activities, such as smoking, just because you can think of someone who was an exception to the rule. Early Signs of Lung Cancer When it comes to cancer, one of the most important things you can do is get an early diagnosis. Early detection will put you in a better position in terms of treatment. Catching the disease before it gets the chance to travel to other parts of the body will make it easier to treat. If it does not spread, physicians can concentrate treatment techniques on specific areas, which can drastically increase your chances of beating it. The main problem that makes cancer so deadly is that you often do not notice until it is too late. Oftentimes, the early signs of disease are easy to overlook. Unfortunately, lung cancer normally does not cause any noticeable symptoms until later on. If you are demographically vulnerable to developing lung cancer, consider paying special attention to these early warning signs: Chronic cough, with no apparent cause. Coughing up blood; you may notice spotting on tissues. Chest, back, or shoulder pain, especially when you take deep breaths or laugh. Inappropriate shortness of breath, which may happen when doing non-strenuous, daily activities that should not cause any breathing problems. Weight and appetite loss, with no apparent cause. Fatigue or feelings of weakness with no known cause. Hoarseness, or having a raspy voice, can be a sign of respiratory problems. Wheezing, even during regular breathing. Chronic bronchitis or pneumonia. Any persistent respiratory infection should be brought to the attention of your physician. As lung cancer advances, the severity of symptoms will worsen for most patients. Advanced Symptoms of Lung Cancer In addition to the symptoms mentioned above, other signs of cancer may manifest after the disease has had time to progress. These symptoms will arise in response to the fact that the disease has entered other parts of the body. How you experience these symptoms will depend heavily on where the cancer spreads to. Bone pain: Can occur anywhere in the body but likely in the hip or the back. Jaundice: The yellowing of skin and eyes is a sign the liver has been disrupted by something. Disturbances to the nervous system: When cancer spreads to the brain, it can cause many different symptoms. These symptoms can include things such as persistent headaches, fatigue, numbness, lightheadedness, seizures, and sudden problems with balancing. When to See a Doctor You should always discuss any major changes in your bodily functions with your doctor. It is impossible to know whether or not something is cancerous until you undergo a medical examination. More than likely, these symptoms are not cancer. This does not mean that you should ignore them. Even if a collection of symptoms is not cancer, it can be a sign of another medical condition. As early intervention is essential for dealing with any cancer, it is important to talk to your doctor as soon as you notice these problems when they become persistent and occur with no explanation.
