Seizures and epilepsies are called by a joint name seizure disorders. In terms of seizure, it is often associated with a sudden brief alteration in the function of the brain while epilepsy is related to CNS disorder which brings in a prone to recurrent seizures. Although seizures display themselves in a different way from individual to individual, they tend to trait a line within a patient.
Seniors with cerebrovascular disease are exposed to the highest rate of getting seizure disorders, especially after they have suffered a hemorrhagic stroke. Usually, the seizures symptoms manifest within the first 24 to 48 hours of a stroke and few patients can even be conflicted by epilepsy. It is suggested that clinically silent strokes may be a main cause of late-onset epilepsy.
However, a hospital-based study has shown that a large range of drugs can not only save lives and get rid of disease but also bring in seizures to the patients. The seizures caused by drugs are called drug-induced seizures. As the ageing process will bring about many series healthy problems, the trend of drug abuse shows no signs of decline among the elderly, especially the abuse of psychotropic medications, which are the most common cause of drug-induced seizures. In addition, bronchodilators, insulin, isoniazid, and lidocaine can lead to multiple seizures. Besides, antipsychotic therapy is not very safe because if it is not performed in a right way, it can become the main cause of drug-induced seizures. If the patient has already been conflicted by a pre-existing seizure disorder, an abnormal electroencephalogram or a pre existing pathology of the CNS or head trauma, the risk will increase further. Besides, if the doses are too high or titration is too rapid, it will also make ways to drug-induced seizures to come into the body. Among all the antipsychotics, clozapine and chlorpromazine carry the highest risk potential and olanzapine may also be closely relevant to the risk based on reports.
Antidepressants drugs vary in their likelihood to cause risk of seizures in therapy. For instance, patients who take 450mg or less bupropion every day will have 0.4% of opportunity to catch drug-induced seizures and bupropion-taken is totally forbidden if the patients had seizure disorder before. Moreover, tetracyclic antidepressant maprotiline can also lead to a higher incidence of seizures than tricyclic antidepressants.
Like young children, traumatic brain injury is also one of the most frequent causes of seizure disorders, which start within the first one to two years following injury. Seizure activity can cause intracranial pressure and make worse brain damage, so it needs to be treated as soon as possible. Additionally, heatstroke, one of the most common diseases in the seniors can increase the incidence of seizure disorders, too. And that injectable benzodiazepines are always in great need during its treatment so as to keep seizures away from attacking the body. What’s more, hypomagnesemia and miscellaneous issues are also the main cause of seizure disorders. Therefore, old people should pay attention to their daily diet, too.
A clear picture of the cause is an essential step to give appropriate and prompt treatment. And knowing how the seizures have triggered provides guidance to the doctors which medicine to be used and how much to be used to tailor the patients’ constitution.
The type of causes can depend on the age of the patients who are conflicted with seizure disorders. And that there are many types of causes of seizure disorders. They are high fever, brain infections, metabolic derangement, inadequate oxygen supply to the brain, structural damage to the brain, fluid accumulation in the brain, prescription drugs, recreational drugs, withdrawal of a drug after heavy use, exposure to toxins.
Some patients have congenital seizure disorders which have nothing to do with the surrounding. Some are born to be more vulnerable to the seizure disorders. Both of the cases are controlled by some genes, which play a significant role in the recurrence of seizure disorders. Besides, oxygen deficit, infections and poor nutrition during pregnancy can also provoke seizure disorders in new born infants because the three can exert negative influence on the development of the brain of the baby. In some severe cases, it can also result in permanent damage of the brain and even cerebral palsy.
Besides, poison is a scarring thing which can increase the incidence of seizure disorders. It contains too high level of carbon monoxide, toxins and so on. To some extents, nearly all drugs can become poisons depending on their doses, including those used to cure seizure disorders. Therefore, patients should strictly follow the doctor’s advice in terms of taking antidepressants or other prescription medications.
In addition, the negative effects of any kinds of brain damage should not be underestimated as it may leave tricky legacies to the patients even after the injury has been completely cured, such as seizure disorders. So it is recommended that people who have suffered this experience should go to the doctor for completely physical checkup. Moreover, alcohol-addiction can increase the incidence of alcoholism, which can become another most popular cause of seizure disorders. Brain tumors does not only increase the risk of getting cancer but also getting seizure disorders due to its likelihood to change the functioning of the brain. Other diseases including strokes and heart attacks can develop seizures because they rob the brain of oxygen. These are two of the most common causes of seizure disorders in the elderly. Besides, onset of seizures can make its grand entry to the body if AIDS, hydrocephalus and menegitis attack the body. Patients of this disease should be more cautious about their healthy condition.
Triggers such as insomnia, exposure to quick flashes of light or computers and too much pressure can become contributing factors to cause the epilepsy to begin. Most of you may have at least one of the bad habits which can spark a seizure and you have to make every effort quit the bad habits. It will help to improve the quality of life and keep series illnesses away from your daily life.
The causes which give rise to the progression of seizure disorders in childhood vary from children of different ages. But a person can pick up seizure disorders just from his heredity, in which any external factor has nothing to do with the cause of disease. With regard to neonates, it is more likely that they will be attacked by seizure if their mothers get series injury or abuse drugs during gestation period. Besides, a birth defect or brain disorder can also underlie the development of epilepsy.
For toddlers under 2 years old, the impact of high fevers cannot be underestimated as it may open doors for seizure disorders. The high fevers are often caused by two typical conditions: heatstroke and infections. So for one thing, parents should remember never expose children directly to sunshine for a long time and take necessary protection measure, such as a sunbonnet or an umbrella. For another, keep their young children away from those who have bad flu or high fevers as toddlers’ immunity is low, making them vulnerable to infection.
Usually, if a child takes up too much nutrients, such as glucose, calcium, magnesium, vitamin B6, or sodium, their risk of being attacked will go higher because it can result in a high blood level of the elements mentioned above. This is the most common metabolic derangements cause of seizure in newborns.
Besides, the development of epilepsy in childhood can be a result from brain injury at or around the time of birth. Thus, mothers should extremely take good care of themselves before giving birth as this is one of the most effective ways to prevent their children from infecting by seizure disorders. If there are members in a family who have seizure disorders or central nervous system malformations, much more attention should pay to the healthy condition of new-born infants due to its high morbidity rate. In conclude, any harm related to the brains can increase the risk of seizure disorders since the harm can bring about inadequate oxygen to make the brain function properly or damage in the structure of the brain.
At present, an abuse of drug has witnessed the considerably high incidence of seizure disorders, especially in the new-born. Generally, high restriction of medical taking is put on pregnant women. Seizures occur to the infants easily when the dosage is too high, or it is not the right medicine. So it is highly recommended that pregnant women take medicine with the dose described and course of treatment. And they must ask their doctors for advice to see if they really need to take the medicine and if the medicine exerts bad influence on their babies’ health. Sometimes it is impossible to tell whether a drug can treat or trigger seizures because the judgment is largely based on the doses of taken. Actually, one medicine can play an important role to bring in or out seizure disorders, such as phenvtoin. Correct dosage can treat seizure disorders while too much dosage can give the opposite performance.
