Occipital lobe epilepsy is fairly rare, and may sometimes be misdiagnosed as migraine when symptomatic. Epileptic seizures are the result of synchronized neural activity that is excessive, and may stem from a failure of inhibitory neurons to regulate properly. [1] It is a disorder with focal seizures in the occipital lobe of the brain.
In focal onset aware seizures, a small part of one of the lobes may be affected and the person remains conscious. This can often be a precursor to a larger focal onset impaired awareness seizure; in such cases, the focal aware seizure is usually called an aura. A focal impaired awareness seizure affects a larger part of the hemisphere and the ...
TEA is a form of focal seizure, which is "the most common variety of adult-onset epilepsy" as opposed to the stereotypical tonic-clonic or grand mal seizure in which affected persons suffer a loss of consciousness and convulse. [11]
Oxcarbazepine, sold under the brand name Trileptal among others, is a medication used to treat epilepsy. [3] [5] For epilepsy it is used for both focal seizures and generalized seizures. [6] It has been used both alone and as add-on therapy in people with bipolar disorder who have had no success with other treatments. [7] [5] It is taken by ...
Todd's paresis (or postictal paresis/paralysis, "after seizure") is focal weakness in a part or all of the body after a seizure. This weakness typically affects the limbs and is localized to either the left or right side of the body. It usually subsides completely within 48 hours. Todd's paresis may also affect speech, eye position (gaze), or ...
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
In endemic areas, neurocysticercosis is the main cause behind focal epilepsy in early adulthood. All growth phases of cysticerci (viable, transitional and calcified) are associated with epileptic seizures. Thus, anti-cysticercus treatment helps by getting rid of it thus lowers the risk of recurrence of seizures in patients with viable cysts.
However, for any given stimulus there may be a large variation in the kind of elicited seizure. For example, reading epilepsy may cause myoclonic jerks in the jaw or may cause focal seizures in the regions of the brain responsible for reading. [2] In reflex epilepsy generalized seizures are more common than focal seizures. [5]
