| Seizures: Know the Types |
|
| How are seizures classified? They are based on a description of the areas of the brain affected during the seizure. EEG changes can show different seizure types. |
|
|
|
| Partial seizures |
|
| In this type of seizure, an electrical disturbance starts in one hemisphere of the brain, and it may not end there. It may move on to other areas, causing a person to become unconscious. Partial seizures can spread to involve both hemispheres of the brain. This resulting seizure is called "secondarily generalized." |
|
| Simple partial seizures |
|
| A person with this type of seizure is still conscious. This person may have twitching of a limb, a funny taste, or an unusual feeling such as pins and needles. These signs and symptoms are largely due to the focus of the seizure within the brain. |
