What increases when there are convulsions in the cerebrum?
During convulsions in the cerebrum, there is an increase in abnormal electrical activity in the brain, leading to uncontrolled muscle movements and possibly loss of consciousness. The convulsions can also increase the risk of injury to the individual experiencing them.
Does smoking decrease epileptic seizure activity?
No.
What is an epileptic fit?
An epileptic seizure is usually caused by some electrical activity in the brain. We all have electrical activity in the brain. If there is an excessive amount, this can cause an epileptic seizure. This can cause the person not to feel well, possibly lose conciousness, and have unusual physical activity because their brain is not working properly. Some physical activity could be very minor, like small movements or could be much larger like physical jolting of parts of the body. A seizure will usually not last very long and the person will soon return to normal.
What is the result if mitosis occurs at an abnormal rate?
This is the definition of cancer. It will produce a large growth with uncontrolled activity.
What causes convulsions?
Convulsions/seizures are caused by abnormal electrical activity in the brain. For a bit of background, the brain is part of the central nervous system, which controls and 'instructs' the body on what to do. The brain sends these instructions out using electrical impulses and signals. If the brain becomes confused, for whatever reason, the electrical impulses may begin to send abnormal impulses to the wrong places and via the incorrect neurons. This causes the body to get confused and results in abnormal twitching and convulsing. People with a medical condition called epilepsy have an abnormal brain electrical activity giving rise to epileptic seizures. Seizures/convulsions can also be caused by a brain tumour or another nervous system disorder. It is vital every seizure is reported to your medical practitioner. If the seizure last for longer than normal, or if it is your first seizure, seek urgent medical assistance or phone for an emergency ambulance.
What is epilespy?
Epilepsy is a brain disorder in which a person has repeated seizures (convulsions) over time. Seizures are episodes of disturbed brain activity that cause changes in attention or behavior.
What does the word epilepsy mean?
a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain.
Is an epileptic fit due to a over load of electicity made by the body?
It is an unusual level of electrical activity in the brain. There is constant electrical activity in the brain. If it is disrupted or an extra amount of it happens it may affect the working of the brain temporarily and the result is a seizure.
How does epileptic drug treatment effect EGG?
Epilepsy is condition due to increased electrical activity in the brain. Most of the anti epileptic drugs act by increasing the substance called 'GABA' in the brain, which is a substance which acts by inhibiting the excess electrical activity in the brain. About the EEG (Electroencephalogram), it is the recording of the electrical activity in the brain. However you must note that the EEG is altered only during the episodes of seizures and it is normal in most of the cases between these episodes. So drug treatment will not effect the EEG taken in the normal state.
What happens when a stimulus activates a receptor?
The activation of a second messenger inside the receiving cell, the triggering of enzyme activity in the cell, and the change of permeability of the cell.
How do you know you have Epilepsy?
Epilepsy is not considered until you have had more than one seizure. In order to be diagnosed with epilepsy, a neurologist will have an EEG done. This reads the electrical activity in your brain. From there, the doctor can determine weather or not you are epileptic.
What are sphenoidal electrodes?
Sphenoidal electrodes are EEG electrodes placed near the sphenoid bone in order to capture electrical activity in the brain's deep structures, particularly the temporal lobes. They are used in neurophysiological studies and monitoring epileptic activity.
