Exercise 5. Complete the words in the following sentences by adding a prefix. Choose from the following: un-, in-, im-, ir-, dis-. An epileptic seizure is ___controlled, chaotic electrical activity in the brain. It alters consciousness and may bring on ___ voluntary movements. Epilepsy may be the result of chemical ___balance but more often the cause is ___known.
In a grand mal epileptic seizure, the victim falls to the ground___conscious and makes twitching movements which may last for several minutes. In a petit mal seizure, the victim may be__aware of things around him for up to thirty seconds but seldom loses consciousness.
In temporal lobe epilepsy, a seizure may result in the victim having ___rational feelings of anger or fear.
Following a stroke, many patients are left with some sort of ____ability.
Brain cells starved of blood are _____able to communicate with the parts of the body they are responsible for.
Exercise 6. Read and translate the text: EPILEPSY Epilepsy is a disorder of brain function characterized by recurrent seizures that give a sudden onset. Epilepsy may be the result of disturbed chemical balance but more often the cause is unknown.
The term idiopathic is used to describe epilepsy that is not associated with structural damage of the brain. Seizures may be generalized or partial. Generalized epilepsy may take the form of tonic-clonic or absence seizures. In tonic-clonic seizures the patient falls to the ground unconscious with the muscle in a state of spasm. The lack of any respiratory movement may result in cyanosis. The tonic phase is replaced by convulsive movements when the tongue may be bitten and urinary incontinence may occur.
Movements gradually cease and the patient may rouse on a state of confusion, complaining of headache, or may fall asleep. Absence seizures consist of brief spells of unconsciousness lasting for a few seconds. During which posture and balance are maintained. The electroencephalogram characteristically shows bisynchronous spike and wave discharges during the seizures and at other times. Attacks are sometimes provoked by overbreathing or intermittent photic stimulation.
In partial seizures, the nature of the seizure depends upon the location of the damage in the brain. Symptoms may include hallucinations of smell, taste, sight, and hearing, and paroxysmal disorders of memory. Throughout an attack the patient is in a state of clouded awareness and afterwards may have no recollection of the event. A number of these symptoms are due to scarring and atrophy affecting the temporal lobe.
The different forms of epilepsy can be controlled by the use of antiepileptic drugs (anticonvulsants). Surgical resection of focal lesions in the brain is appropriate in a strictly limited number of cases.
