Focal attacks are often preceded by some kind of aura, such as numbness, tingling or spasm in a certain part, and unconsciousness. Exercise or muscle clonic convulsions often occur.
Most of them are confined to one hemisphere, resulting in partial progressive convulsions. It will stop in half a minute to a few minutes. Temporary paralysis of limbs. It can also spread to the whole brain, causing generalized convulsion, and then lose consciousness and generalized convulsion, which is called localized seizure followed by generalized convulsion.
Extended data:
First, focus attack:
Exercise or muscle clonic convulsions often occur. Most of them are confined to one hemisphere, resulting in partial progressive convulsions. It will stop in half a minute to a few minutes. Temporary paralysis of limbs.
It can also spread to the whole brain, causing generalized convulsion, and then lose consciousness and generalized convulsion, which is called localized seizure followed by generalized convulsion.
Positive results can be found in EEG. Local lesions can often be found by CT or MRI, but only ventricular enlargement or local cerebral cortex atrophy can be found in some cases, and no lesions were found in 1/4 ~ 1/3 cases. It is necessary for the latter to follow up regularly.
Second, the lesion damage:
There are often some premonitions, such as numbness, tingling or spasm in a certain part, without conscious disturbance. Exercise or muscle clonic convulsions often occur. Most of them are confined to one hemisphere, resulting in partial progressive convulsions. It will stop in half a minute to a few minutes.
Temporary paralysis of limbs. It can also spread to the whole brain, causing generalized convulsion, and then lose consciousness and generalized convulsion, which is called localized seizure followed by generalized convulsion. Positive results can be found in EEG.
