What is epilepsy?
Epilepsy is a neurological condition that from time to time produces brief disturbances in the normal electrical functions of the brain. Normal brain function is made possible by millions of tiny electrical charges passing between nerve cells in the brain and to all parts of the body. When someone has epilepsy, this normal pattern may be interrupted by intermittent bursts of electrical energy that are much more intense than usual. They may affect a person's consciousness, bodily movements or sensations for a short time.
These physical changes are called epileptic seizures. That is why epilepsy is sometimes called a seizure disorder. The unusual bursts of energy may occur in just one area of the brain (partial seizures), or may affect nerve cells throughout the brain (generalized seizures). Normal brain function cannot return until the electrical bursts subside. Conditions in the brain that produce these episodes may have been present since birth, or they may develop later in life due to injury, infections, structural abnormalities in the brain, exposure to toxic agents, or for reasons that are still not well understood. Many illnesses or severe injuries can affect the brain enough to produce a single seizure. When seizures continue to occur for unknown reasons or because of an underlying problem that cannot be corrected, the condition is known as epilepsy. Epilepsy affects people of all ages, all nations, and all races. Epilepsy can also occur in animals, including dogs, cats, rabbits, and mice.
What is the difference between seizures and epilepsy?
Seizures are a symptom of epilepsy. Epilepsy is the underlying tendency of the brain to produce sudden bursts of electrical energy that disrupt other brain functions. Having a single seizure does not necessarily mean a person has epilepsy. High fever, severe head injury, lack of oxygen -- a number of factors can affect the brain enough to cause a single seizure. Epilepsy, on the other hand, is an underlying condition (or permanent brain injury) that affects the delicate systems which govern how electrical energy behaves in the brain, making it susceptible to recurring seizures.
Which doctors treat epilepsy?
Neurologists, pediatric neurologists, pediatricians, neurosurgeons, internists and family physicians all provide treatment for epilepsy. Specialized care for people whose seizures are difficult to control is available in large medical centers, neurological clinics at university and other hospitals, and from neurological specialists in private practice.
Is epilepsy ever contagious?
No, epilepsy is never contagious. You cannot catch epilepsy from someone else and nobody can catch it from you.
What should I consider if there has been only a single seizure?
When a child or adult has never had a seizure before, the first seizure is usually followed by a careful medical evaluation to help the doctor decide whether to recommend treatment with seizure-preventing drugs, or to wait and see whether it occurs again. The most important factor in deciding whether to begin drug treatment for a single seizure is the probability of further seizures. Physicians use both diagnostic tests and careful evaluation of the seizure itself to determine how likely it is that the patient may have more seizures in the future. Age, family history, and possible causes of the seizure are among the factors that are considered. Non-medical issues, such as loss of driver's license or worries about impact on employment, may also enter into the decision. In many cases, the doctor will recommend waiting to see if another seizure occurs before beginning treatment.
In about seven out of ten people with epilepsy, no cause can be found. Among the rest, the cause may be any one of a number of things that can make a difference in the way the brain works. For example, head injuries or lack of oxygen during birth may damage the delicate electrical system in the brain. Other causes include brain tumors, genetic conditions (such as tuberous sclerosis), lead poisoning, problems in development of the brain before birth, and infections like meningitis or encephalitis. Epilepsy is often thought of as a condition of childhood, but it can develop at any time of life. About 30 percent of the 125,000 new cases every year begin in childhood, particularly in early childhood and around the time of adolescence. Another period of relatively high incidence is in people over the age of 65.
What should I do if I suspect a seizure disorder?
If you think you or a loved one might be having seizures, it is important to discuss with your physician what has been happening. Keep a record of how often the unusual episode occurs, the time of day it happens and what form it takes. Giving the doctor this information will help him or her determine if what you are describing might be a type of epilepsy. (http://www.epilepsyfoundation.org/)
IVH is described here: In infants (Wikipedia Article, that actually is quite good)
This type of hemorrhage is particularly common in infants, especially premature infants or those of very low birth weight.[2] The cause of IVH in premature infants, unlike that in older infants, children or adults, is rarely due to trauma. Instead it is thought to result from changes in perfusion of the delicate cellular structures that are present in the growing brain, augmented by the immaturity of the cerebral circulatory system, which is especially vulnerable to hypoxic ischemic encephalopathy. The lack of blood flow results in cell death and subsequent breakdown of the blood vessel walls, leading to bleeding. While this bleeding can result in further injury, it is itself a marker for injury that has already occurred. Most intraventricular hemorrhages occur in the first 72 hours after birth.[2] The risk is increased with use of extracorporeal membrane oxygenation in preterm infants.[3]
The amount of bleeding varies. IVH is often described in four grades:
- Grade I - bleeding occurs just in the germinal matrix.
- Grade II - bleeding also occurs inside the ventricles.
- Grade III - ventricles are enlarged by the blood. (ßAiden’s Grade)
- Grade IV - there is bleeding into the brain tissues around the ventricles.
Grades I and II are most common, and often there are no further complications. Grades III and IV are the most serious and may result in long-term brain injury to the infant. After a grade III or IV IVH, blood clots may form which can block the flow of cerebrospinal fluid, leading to increased fluid in the brain (hydrocephalus).
There has been various therapies employed into preventing the high rates of morbidity and mortality, including diuretic therapy [4], repeated lumbar puncture [5], streptokinase therapy [6] and most recently combination a novel intervention DRIFT (drainage, irrigation and fibrinolytic therapy). DRIFT has been tested in an international randomised clinical trial, although it did not significantly lower the need for shunt surgery, severe cognitive disability at 2 years Bayley (MDI <55) was significantly reduced [7]. Repeated Lumbar punctures is used widely to reduce the effects in increased intracranial pressure and an alternative to ventriculo-shunt (VP) surgery that cannot be preformed incase of intraventricular haemorrhage. The relative risk of repeated lumbar puncture is close to 1.0 therefore it is not statistically when compared to conservative management and does raise the risk of subsequent CSF infection [8].
A Premature Baby's Prayer
God bless the little child behind the plastic wall
For all he knows is the ringing of the bells and
the blurred images around him. He has been taken
from my womb without warning and I long to hold him
in my arms.
Lord, I ask in your name that my child be healed.
I am willing to accept your decision no matter what
it will be. I am willing to take on the responsibilities
for caring for this child. I am willing to give this
child love and understanding no matter the cost.
Please Lord help me to accept reality and what has
happened without explanation or warning. Help me
face the fact that this is not my fault and that
I was given a special task to complete here on Earth.
God give my child the strength to make it through another
second, minute, hour and day as each moment is
a blessing and a triumph from heaven.
God, may you give the strength and compassion
to the caregivers and nurses that take care of my child
May you keep my child protected and free from all injury
and pain.
Please take away the guilt and burden from my heart dear
Lord. It is heavy and I feel it is all my fault.
Take it away dear Lord. Sweet Jesus allow me the strength
and understanding I need to communicate with the Doctors
and Nurses.
As you see dear Lord, I am at your mercy for the life of
my child. Please leave him here on Earth and know that
I will provide all the love and understanding that
this child needs. I accept the challenge and will be
your humble servant dear Lord.
