What Is a Focal Lesion?

Focal seizures are often preceded by certain signs, such as a local tingling, tingling, or spasm, without an unconscious disturbance. Exercise or muscle clonic convulsions often occur. Mostly confined to one side of the hemisphere, producing progressive progressive seizures. It lasted for half a minute to several minutes. The extremity has temporary paralysis. It can also spread to the whole brain, causing systemic convulsions, like a major attack, loss of consciousness, systemic tics, which is called a localized seizure secondary to systemic spread. EEG can be found positive. CT or MRI can often identify local lesions, but there are also only enlarged ventricles or local cerebral cortex atrophy. In 1/4 to 1/3 of cases, no lesions can be found at all. Regular follow-up reviews are necessary for the latter. ^[1]
