Clinical Classification

Clinical Information

  • Epilepsia Partialis Continua

    a variant of epilepsy characterized by continuous focal jerking of a body part over a period of hours, days, or even years without spreading to other body regions. contractions may be aggravated by movement and are reduced, but not abolished during sleep. electroencephalography demonstrates epileptiform (spike and wave) discharges over the hemisphere opposite to the affected limb in most instances. the repetitive movements may originate from the cerebral cortex or from subcortical structures (e.g., brain stem; basal ganglia). this condition is associated with russian spring and summer encephalitis (see encephalitis, tick borne); rasmussen syndrome (see encephalitis); multiple sclerosis; diabetes mellitus; brain neoplasms; and cerebrovascular disorders.

Patient Education


Epilepsy

Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. People may have strange sensations and emotions or behave strangely. They may have violent muscle spasms or lose consciousness.

Epilepsy has many possible causes, including illness, brain injury, and abnormal brain development. In many cases, the cause is unknown.

Doctors use brain scans and other tests to diagnose epilepsy. It is important to start treatment right away. There is no cure for epilepsy, but medicines can control seizures for most people. When medicines are not working well, surgery or implanted devices such as vagus nerve stimulators may help. Special diets can help some children with epilepsy.
